Is it possible to connect a boiler through an extension cord

Is it worth it to be afraid of heating the fork in the water heater?

The purpose of the plug outlet is the switch of the fork with an electric network. With normal functioning, a current passes through the contacts with minimal heat release. In some cases, when inserting the fork into the outlet, a breakdown occurs. The higher the power of the device turned on, the more intense sparking and crack. The temperature of the electric arc is very high, a characteristic smell of molten plastic appears.

A rare case when the zero wire in the electric shield begins to heat up. For example, with a recent laying of a resistive cable for heating the floor in the apartment. You should know that the zero conductor does not have a dangerous potential for life, and its temperature should be within the room, but not higher.

What can cause such heating?

  • With an uneven distribution of currents. This means that on a working zero, the current strength exceeds the current, which passes through the phases. Self-regulating cables that are used to heat pipes, due to their power lead to this result. At the same time, zero can not only overheat, but also burn out.
  • Bad contact of the zero wire with a zero tire. Accompanied by unpleasant crackling sound and sincerity. It is enough to tighten the contact or check the nearest twisting place and the problem will be eliminated.
  • Connecting electrical devices that directly affect the frequency. These are: induction furnaces, impulse consumers, heating cables, light sources based on LEDs, etc.

The consequences of low.quality contact of the zero wire

The water heater fork is heated

Tighten, and if the heating is eliminated, you can not change the outlet.

I join that. what Root said but still important. What kind of outlet. Rather, what load is designed for

And body material. Search with a ceramic building. They are usually more powerful. And of course not Chinese.

The outlet melts because too much load passes through it. Over time, contact plates or springs weaken and they are formed. It is necessary to replace the socket or bend and clean the contacts, but I would put a two.lane machine instead of a socket.

The problem was most likely in contact plates or springs, they weakened over time and contact began to deteriorate. Therefore, the socket began to melt. It would be better to replace it with a new one for reliability.

The main methods of connection

When ordering a boiler for home or commercial use, it is important to understand that, depending on the design features of this product, there are two methods of connecting it to the mains.

The boiler you have chosen can be equipped with a familiar euro-lobe, then, in order to connect it correctly, you will have to install a socket of the corresponding type in the immediate vicinity of the water heater. Please note that such an outlet needs to be equipped with your own automatic for 16 amperes.

Another option is possible: the boiler you have bought does not have a fork and a cord. In this case, it will have to be directly connected to the electrical panel through an automaton. You can turn off the tank with this connection only using an automatic relay. It is recommended to install the switch closer to the tank, taking care of the moisture.proof case for it. This will allow you to quickly de.energize the boiler in the event of any unforeseen situation.

Connection process

Before shend directly to the installation process, take care of all the nuances of the upcoming process. Given that you will have to deal with water and electricity at the same time, you need to remember the observance of safety precautions.

We recommend that you purchase the following materials in advance:

  • Three.wire wire,
  • outlet,
  • clamps for attaching the cable to the wall,
  • Island,
  • Double machine gun,
  • fork (it will be needed if the boiler is equipped exclusively by terminals and does not have a network cord).

The above list requires clarification. It is worth noting that boilers are often sold in factory configuration, but without consumables that are needed for high.quality and safe installation.

The wire should be three.core, isolated, copper. One of the veins is just needed for grounding. If we talk about its parameters more specifically, then you will find this information in the instructions for the device. So, the cross section of the wire directly depends on the power of the boiler, usually this indicator is not less than 1.5 mm² (for tanks with a capacity of up to 1.5 kW).

Note that for connecting a boiler, three.core VVG or NYM three.core cables are ideal. Their characteristics must correspond to the power of the boiler.

The length of the wire must be calculated on the spot, depending on the location where you plan to mount the tank. Do not forget to add 1 meter to unforeseen circumstances.

Tip: If you do not want to spend time calculating the section parameters, you can proceed from a simple rule: for a heating device with a capacity of up to 4 kW, a wire diameter is quite enough from 1.7 to 2 mm.

It is important to treat a great responsibility to the selection of a socket and a fork (if the basic equipment requires this). These components are selected for considerations of maximum safety, adhering to the following parameters:

  • for boilers up to 1.5 kW-10 amperes,
  • for boilers with a capacity of up to 4 kW-16 amperes. Pay attention to the marking. you need an IP44 defense degree.

Important: regardless of whether your RCD boiler (protective shutdown) is equipped with a network fork, when connecting this device, you must take care of installing a difavtomat. It is chosen in the same parameters as the socket.

In more detail about how to make a choice between these devices, you will learn from

In addition to consumables and additional electrical appliances, you will need some tools. Connecting the boiler to the mains does not require something special, however, in our opinion, this checklist will be useful to the home master. Before starting the installation of a boiler, check if you have the following tools at hand:

Important: taking into account the fact that you will have to work with wiring, make sure all the tools are equipped with insulating handles.

A step.by.step algorithm

When installing the boiler, you should start with the simplest. carefully read the operating manual or instructions for it. This document, if it does not answer all your questions, will certainly help to understand the mechanism of installation of a storage heater for water.

In addition to the text with the instructions, how to install an electrical appliance, in the instructions you will find pictures and diagrams of the device itself and its connection to both the power supply and water supply. The fact that boilers are with a cord, and without it, you already know. Please note that the equipment of the water tank may differ in another parameter. the presence or absence of an RCD.

The next step is to outline the place where you install the socket under the boiler. Experienced masters recommend placing it in the corridor. So it will be correct from the point of view of safety precautions. Given the fact that boilers are usually mounted in rooms with high humidity (in the bathroom, in the kitchen or in the toilet), the automatic is advised to place in the protective case on the wall if there is no place in the shield for it.

Ideally, for the water heater, it is necessary to lay a separate power fishing line for a trimmer from the electric meter, since the consumption of electricity by the boiler is quite high. at least 2 kW. In extreme cases, the tank for heating water can be connected to the divorce box, taking care of the installation of the machine on this segment of the wire.

Let’s talk about grounding. this important nuance of the boiler installation is not recommended to ignore. It is important to understand where exactly the grounding wire will go. If your shield is equipped with a ground tire, to which one of the cable core will go, then there will be no problems with this at all.

Why is it so important to take care of grounding? Firstly, its absence increases the likelihood of a threat to get a shock. Secondly, the service life of the electrical appliance is significantly reduced. This is due to corrosion of metal provoked by the accumulation of static electricity. In the documentation for the water heater you will find both grounding scheme and terminal for him.

How to connect a boiler through an RCD

Back to the topic of grounding boiler. Given that in most old apartments, the wiring was made by a two.wire cable, you should know that when installing a boiler, there is no way to connect a third (grounding) tire.

In such cases, experts recommend protecting the fishing line for a boiler power trimmer using an automatic machine or RCD (protective shutdown device). It reacts even to the weakest leakage of current in the line and turns off the device from the network when the threat of failure occurs. You can learn more about the device of the RCD in more detail from this video.

Suppose that your house has a third vein that performs the function of grounding. Then you have nothing to worry about. The boiler forking is provided for grounding terminals. By installing a socket under the water heater or by connecting the latter directly to the machine, you use a separate core in yellow-green insulation. It is connected to the grounding contact of the boiler.

Safety and useful tips

Before you do electrical work, make sure that the apartment is de.energized. To do this, turn off the machine on the shield. You can turn it on again after the cable wiring is carried out, the installation of the machine and the outlet for the boiler. These works are performed according to the prepared electric circuit.

Varieties of extension cords

Extension cords differ in functionality, price and purpose, they are:

For the safe operation of each type of equipment, you need its own extension cord with a certain set of functions and indicators.

Household extension cord without grounding

The most budget option, but the least reliable, quickly overheats and often melts. Suitable for a temporary connection of a simple electrical appliance, for example, for a table lamp, the power of which rarely exceeds 150 watts.

Such a model is convenient in situations when it is necessary to periodically turn on and turn off all the electrical appliances working from the extension cord. In this case, you will not have to regularly pull out the fork of each gadget from the outlet, which is especially important with a long absence of a house during weekends or vacations.

Extension cord with a button. an alternative to a network filter. The case is durable and reliable, most often made of special fireproof plastic. However, this option does not give a complete guarantee of protection of technology during voltage malfunctions.

A device from a cable, fork and reinforced socket allows you to bring electricity to powerful household appliances as safely as possible, for example, to a washing or dishwasher. The power extension cord is protected from the effects of external forces and voltage jumps. Additional functions in such devices:

  • grounding for neutralization of the excess voltage in the event of an accident at the substation;
  • Thermal switch that protects against overheating or closing of the electrical wiring.

We deal with the digist for understanding what power the outlet or extension cord is withstanding, multiply the voltage by the rated current. Default voltage in the network 220 volts. A 5 ampere socket withstands a power of 1100 watts; A 10 ampere socket withstands a power of 2200 watts; 16 ampere socket can withstand a power of 3520 watts.If you calculate these indicators in advance, then there will be no problems with connecting powerful or several ordinary devices at the same time.

Safe use rules

As with any electrical appliance, when using the extension cord, it is important to observe security measures. Regardless of the extension cord, its operation is a temporary measure. Upon completion of the equipment, it is necessary to disconnect it from power.

We unwind the extension cord completely before starting work. Otherwise, the neighboring turns of the wires will warm up each other, which will lead to a fire. We are convinced that the extension cord’s power is above the power of the connected electrical appliances. If you overload the extension cord, it will begin to melt, and the connected equipment with a high probability will fail. Choose an extension cord with protective curtains if small children are present in the house. We make sure that the outlet is sealed if we use the extension cord in the bathroom or in the kitchen. Do not connect electrical appliances with wet hands and do not allow contact for plugs of the device with water. We do not improve the design of the device yourself. such actions lead to fires, impaired wiring insulation and injuries. Disconnect the extension cord with any malfunction of the network cord, a fork for a device or socket. Do not squeeze the network wire with the door and do not lay it under the carpets. Otherwise, the integrity of the cord is violated, which leads to a short circuit or fire. We do not include the extension cord in the extension cord. this is the fastest way to overload the power grid, there is a great risk of fire and disabled equipment without the possibility of its restoration.

What to do if you smell burning wiring? De.energize in the apartment all powerful electrical appliances: washing and dishwasher, refrigerator, iron, microwave, kettle. Optimal output. turn off the machines in the electrical panel.

Is it possible to connect a boiler through an extension cord

For a comfortable living in the house, when you want to constantly use hot water, and not depend on the repair schedule of monopolists that can turn off this water for an unknown number of days, many are thinking about purchasing a boiler.

Most often, the choice falls towards the accumulative water heater. They come in different companies Ariston, Drazhitsa, Baxi, etc.D., forms and structures. flat, cylindrical or elongated.

The installation of cold and hot water pipes may differ in them, but they are connected to the 220V network, they are all the same.

Many mistakenly believe that in order to connect the boiler, just stick the plug in the outlet and do not worry about more. However, they forget that it is in the boiler, in the event of a violation of isolation, through water, direct contact of electricity with a person can occur through water.

possible, connect, boiler, extension

What should be paid to special attention when connecting the boiler:

When repairing in new apartments, a separate wiring is usually carried out directly from the shield for the boiler. If you want to connect the boiler to the old common wiring, on which several sockets are already connected, be sure to make sure that it will withstand the boiler power.

In most cases, with a power of up to 3.5 kW, the wiring should be performed by a 3-residential copper cable of VVGGNG-LS, with a cross section of at least 2.5mm2.

The three.wire cable is necessary in order to ensure constant connection with grounding.

Boiler connection machine, choose two.pole. The rated current of the machine 16a (enough at a boiler power up to 3.5 kW).

With a load of up to 2 kW, a circuit breaker with a rated current 10A is suitable.

If the boiler is connected from the outlet, then the outlet should have an IP44 protection degree. These are sockets for rooms with increased humidity level.

Remember that a socket in the bathroom can be placed only in certain places. And there are zones where to do this is strictly prohibited. Read more about this in the article “The Roset in the Bathroom. 5 Rules for Accommodation”.

Although many are opponents of connecting electric heaters through the outlet, but only in this way can a visible breakdown of conductors (phases and zero) be ensured when turning off, as required by safety regulations.

And also for those water heaters who initially go with forks in the kit, if they cut them off, sometimes you can lose a guarantee. Therefore, read the instructions.

If it says that this boiler can be connected in two ways

In addition, if you need to dismantle the device from the wall, if you have a fork, you do not need to call an electrician to turn it off from power. I pulled the fork, take off, rearrange, do what you want.

Powerful boilers over 3.5 kW, should only be connected through the circuit breaker, the outlet connection is not permissible here.

The cable must be started so that there are no intersections with water pipes and places of the future fastener of the heater.

In the nourishing line of the boiler, the installation of an RCO. a protective shutdown device is required. Choose it according to the current one order higher than the current of the machine.

Why is it better than 10mas, and not more, you can understand from this sign of exposure to current on the human body:

A significant minus here, that on 10m protection can be falsely working. Especially if your water heater has been hanging for several years and in places of connection of terminals, such condensate and moisture are often formed.

How to check the false this trigger or is faulty? To do this, use the multimeter.

Turn off the supply machine or pull the fork from the outlet and disconnect the standard ground from the titanium body.

Then remove the terminal clamps from the heater, and with the help of probes, measure the resistance between the boiler housing and the heating element.

If the heating is in good condition, the indications on the multimeter screen should strive for infinity, that is, to be about the following:

With a breakdown and damage to the heater, they will either be zero, but most often they can be several hundred and even a kilo. In the photo below this is the option ~ 500k.

Connection of the boiler to the mains | Good.natured plumber

To connect a household electric storage water heater to electricity, so that it works correctly, so that it works more efficiently, does not grow in a scale and does not destroy from corrosion so that its tank serves longer, so as not to get a shock when touching the body of a water heater or mixer, so that when the emergence of emergency situations ceased to supply electricity to it, so that when it breaks it, they could not find the reason for the refusal to be repaired under the guarantee, even trying with all your might, you need to carefully read the instructions and follow what it is written there.

Crazy, climbed on the list of participants, I thought I would find our third opponent. But the Golimim does not streamline the alphabet on the mobile

Let’s figure out the connection of one boiler model to the mains according to the instructions. For example, take Ariston Sht.el 50 V for Instructions for it: https: // ariston.Iqbuy.ru/vodonagrevateli-ass/pass.We open the instructions and read. Next I will make clippings from this instructions. If the whole instruction is interesting, open and read. So, start: 1. (Merloni Termosanitari is not responsible for the damage caused by the incorrect installation by the User or the incorrect execution of the provisions of this leadership.) This means that if you did something wrong as it is said in the instructions, then in case of its breakdown they will not repair it under warranty and no responsibility for the consequences of non-compliance with the instructions.2. (Electric wiring must comply with the rules for the installation of electrical installations (PUE).) This means that before turning on the boiler to the network, you need to look at the characteristics of the electrical wiring to which the boiler will be connected, open the PUE and check if this PUE wiring corresponds to. If it does not correspond, then install the wiring that corresponds to the PUE.3. (Check the correspondence of the voltage in the mains with the data indicated on the passport plate.) This means, you need to check that the voltage in the network is 220 volts. four. (Check the correctness of the completed grounding, in accordance with the current norms and rules. A network socket for a water heater must have a grounding contact and be properly grounded. Grounding wires and neutrals should be different and easily identified. Attention: if the water heater is not grounded, then in the case of a short circuit of the RCD (a protective shutdown device), supplied in the kit may not work. this is dangerous!) For this, the best option is to call an electrician who will check the correspondence of your grounding with the PUE standards with a special device, and if it does not meet these standards or grounding at all, then it will correct this situation. The electrician must be a competent and preferably experienced, not half.drunk neighbor with pliers and soldering iron.5. (Do not use any adapters or extensions to connect a water heater. It is forbidden to replace the water heater plug with another fork. Do not use sockets connected to portable or drum extension cords.The power of the electric water heater should be carried out from a separate electric line from the electric distribution shield. It is not allowed to connect additional electrical devices to this line.) I think there is nothing to comment on, and so everything is clear.6. (The power supply socket of the heater should be in a dry place, at a distance from the sources of water spray.) There is also nothing to comment on.7. (To turn off the heater from the network, use a two.pole switch with a gap between the open contacts of at least 3 mm.) This means that before connecting the boiler to the machine, you need to select an automatic machine with such characteristics.If an RCD is not installed on a boiler, then buy a modular RCD (preferably not electronic, but electromechanical) with a trigger for a current leak of not more than 30m. The rated current of the machine in this scheme should not be higher than the rated current of this RCD, it is even desirable that it be below. For example, if I connect a boiler with a capacity of 2.5 kW, I use the VVGNGU 3×2 cable.5, two.pole automaton C16A, RCD 16A/10MA, or 16A/30MA depending on the situation. You can use a difavtomat C16A/10MA, or C16A/30MA instead of an automatic machine and an RCD.

Now I will briefly talk about the role of the magnesium anode installed in the boiler.It is needed to take the wandering currents to the ground, which appear in the boiler, preventing the corrosion of Ten and Back and the prevention of intensive fraction of the cape of Ten and the Boiler tank. It fully fulfills its function only if the boiler housing is grounded according to PUE (see above). As the anode destroys the anode, it must be changed and the tank is cleaned from the scale and everything that has accumulated in it. When the anode is completely collapsed, the heating ward and the boiler tank will begin to collapse and intensively grow in a scale. The heater overgrown with a scope will overheat due to the fact that the scale will interfere with the transfer of the heat of the heater and burn. Therefore, it is necessary to change the anode in time, avoiding its complete destruction and periodically clean the tank from scale and everything that has accumulated in it. The new anode will cost cheaper than the new heater and, especially, a new boiler.

Crazy, regarding the choice of a rating of the UZO leakage current: when choosing a setting of the UZO leaking current, it is necessary to remember that it should be at least 3 times more than (working TOK0.4 DINLY Line0.01) (SP 31-110-2003). That is, in the case of a boiler 2 kW and current, respectively, 9.1A, as well as with a line length 10 meters, the leakage current will be 9.10.410.01 = 3.74 mAh. 3.743 = 11.22. That is, on a boiler of 2 kW, the rating of the TRASE current of the RCD should be at least 30 mA.Well, in general, on such powerful devices you need to put 30 mA, of course. Washing, boiler, dishwasher, etc.P….RCD 10M should be put on wet rooms on other sockets and lighting

I agree. RCD 16A/10ma ​​I installed as much as 1 time. On a boiler 1.5 kW. The length of the line from the RCD to the heater is about 3 meters. Works. I mainly leave the standard RCDs that are installed from the plant on the boiler cord near the fork. They have parameters 16a/30ma. And in the store on sale I see an RCD only 16A/30m. Therefore, I usually put them in the event that it is possible to convince the customer. Usually no one wants to buy an RCD for an incomprehensible reason even if there is money for it.

Power Your Furnace With A Generator During A Power Outage

Very often, in many recent boiler models, an RCD with a 15ma leak current is already going built into a cable for connecting to a socket. In this case, installing an additional protection apparatus from the leakage current in the shield may not be required.

However, do not forget that such a built.in RCD will protect against leakage only if it is damaged in the heater itself, but will not protect you with a malfunction directly in the outlet or supplying wiring before it.

The question is electricians

In the san.the node with the boiler turned on was cut down by the entrance to 16a. I checked the outlet-all in order.A boiler in another outlet works. I connected a boiler to an old outlet through an extension cord, the machine does not cut down. Advise what is the matter. (The boiler has previously worked for 3 years without problems)

When checking the boiler, you should insert a fork into an identical outlet (t.e. With grounding contacts). Try to a socket to connect another grounding boiler with grounding. If cuts down, the case is in the outlet and/or lines. The extension cord should also be with a grounding wire and contacts in sockets. But the case smacks of a breakdown of isolation in one of the tenants (try to catch the buttons on different shades in turn) or wires in the boiler itself.

Check the cable itself from the outlet to the machine. Replace the machine itself.

Colleagues, the boiler works. Only through the extension cord.

The reason is not at all in the sore at all but in the thread itself.where the thread is shorted, you need to see the contacts.there can be many factors, but not the bore itself

What does it mean in the old outlet? Let’s get together with your thoughts and formulate the question in a non-romance if you want to cure a sick tooth by phone.

Question: And again, connect the boiler to the old outlet without an extension cord, the machine operates?

It can be assumed that in the outlet into which the boiler is connected, poor contact, or there is the possibility of close.

Please specify you have a diphthor? Extension cord or not? And as I understand it, when connecting to the outlet, knocks out and if you connect the extension cord in the same socket and works. If not so correct)

The machine is knocked out with an increased acceptable load on the group that is nourished by the 16A automaton is approximately 3 kilowatts.2 kV boiler 1.5k te kettle, try not to load this gr. During the operation of the boiler.

Grind acry-lactic primer 2 times. Let her dry and don’t even worry about the bubbles. Of course if he sews, exfoliate in front of the primer. Good luck to you.

It is necessary to call the cable if with the cable everything is in the way the cross.section of the wire does not correspond with the loading of the Boller check the mole of the Boller and compare

The machine just doesn’t work. For three years, contact and cable have weakened or burned out in the circuit and, first of all, the joints began to heat up. It is necessary to check all the connections: a camshaft, a fork, joints in the boiler itself, a16 zero tire and earth.

the cause in the threads the carriage must be checked.

What do we have: 1. Three years of uninterrupted work 2. From another outlet. works 3. Through the extension cord from the “working” outlet. works. Conclusions: this is not a short circuit (short circuit) in a rosette (through an extension cord. it works), neither in a boiler (a boiler works from another outlet and through an extension cord) the introductory device is properly. A possible and most likely reason. in the boiler, the insulation has lost its dielectric properties and the current leaks through the grounding conductor (I agree with Artyom Kondratovich), provided that the introductory device is an RCD or differential automatic machine. By the way, in the country, my neighbor had a similar case, but there was a breakdown on the body of one of the hets (KZ) and at the input there was simply an automatic circuit breaker. I turned off one heater and everything worked, but, essno, heated much slower.

Remember that a socket in the bathroom can be placed only in certain places. And there are zones where to do this is strictly prohibited. Read more about this in the article “The Roset in the Bathroom. 5 Rules for Accommodation”.

Although many are opponents of connecting electric heaters through the outlet, but only in this way can a visible breakdown of conductors (phases and zero) be ensured when turning off, as required by safety regulations.

And also for those water heaters who initially go with forks in the kit, if they cut them off, sometimes you can lose a guarantee. Therefore, read the instructions.

If it says that this boiler can be connected in two ways

In addition, if you need to dismantle the device from the wall, if you have a fork, you do not need to call an electrician to turn it off from power. I pulled the fork, take off, rearrange, do what you want.

Powerful boilers over 3.5 kW, should only be connected through the circuit breaker, the outlet connection is not permissible here.

The cable must be started so that there are no intersections with water pipes and places of the future fastener of the heater.

In the nourishing line of the boiler, the installation of an RCO. a protective shutdown device is required. Choose it according to the current one order higher than the current of the machine.

possible, connect, boiler, extension

Why is it better than 10mas, and not more, you can understand from this sign of exposure to current on the human body:

A significant minus here, that on 10m protection can be falsely working. Especially if your water heater has been hanging for several years and in places of connection of terminals, such condensate and moisture are often formed.

How to check the false this trigger or is faulty? To do this, use the multimeter.

Turn off the supply machine or pull the fork from the outlet and disconnect the standard ground from the titanium body.

Then remove the terminal clamps from the heater, and with the help of probes, measure the resistance between the boiler housing and the heating element.

If the heating is in good condition, the indications on the multimeter screen should strive for infinity, that is, to be about the following:

With a breakdown and damage to the heater, they will either be zero, but most often they can be several hundred and even a kilo. In the photo below this is the option ~ 500k.

Connection of the boiler to the mains | Good.natured plumber

To connect a household electric storage water heater to electricity, so that it works correctly, so that it works more efficiently, does not grow in a scale and does not destroy from corrosion so that its tank serves longer, so as not to get a shock when touching the body of a water heater or mixer, so that when the emergence of emergency situations ceased to supply electricity to it, so that when it breaks it, they could not find the reason for the refusal to be repaired under the guarantee, even trying with all your might, you need to carefully read the instructions and follow what it is written there.

Crazy, climbed on the list of participants, I thought I would find our third opponent. But the Golimim does not streamline the alphabet on the mobile

Let’s figure out the connection of one boiler model to the mains according to the instructions. For example, take Ariston Sht.el 50 V for Instructions for it: https: // ariston.Iqbuy.ru/vodonagrevateli-ass/pass.We open the instructions and read. Next I will make clippings from this instructions. If the whole instruction is interesting, open and read. So, start: 1. (Merloni Termosanitari is not responsible for the damage caused by the incorrect installation by the User or the incorrect execution of the provisions of this leadership.) This means that if you did something wrong as it is said in the instructions, then in case of its breakdown they will not repair it under warranty and no responsibility for the consequences of non-compliance with the instructions.2. (Electric wiring must comply with the rules for the installation of electrical installations (PUE).) This means that before turning on the boiler to the network, you need to look at the characteristics of the electrical wiring to which the boiler will be connected, open the PUE and check if this PUE wiring corresponds to. If it does not correspond, then install the wiring that corresponds to the PUE.3. (Check the correspondence of the voltage in the mains with the data indicated on the passport plate.) This means, you need to check that the voltage in the network is 220 volts. four. (Check the correctness of the completed grounding, in accordance with the current norms and rules. A network socket for a water heater must have a grounding contact and be properly grounded. Grounding wires and neutrals should be different and easily identified. Attention: if the water heater is not grounded, then in the case of a short circuit of the RCD (a protective shutdown device), supplied in the kit may not work. this is dangerous!) For this, the best option is to call an electrician who will check the correspondence of your grounding with the PUE standards with a special device, and if it does not meet these standards or grounding at all, then it will correct this situation. The electrician must be a competent and preferably experienced, not half.drunk neighbor with pliers and soldering iron.5. (Do not use any adapters or extensions to connect a water heater. It is forbidden to replace the water heater plug with another fork. Do not use sockets connected to portable or drum extension cords.The power of the electric water heater should be carried out from a separate electric line from the electric distribution shield. It is not allowed to connect additional electrical devices to this line.) I think there is nothing to comment on, and so everything is clear.6. (The power supply socket of the heater should be in a dry place, at a distance from the sources of water spray.) There is also nothing to comment on.7. (To turn off the heater from the network, use a two.pole switch with a gap between the open contacts of at least 3 mm.) This means that before connecting the boiler to the machine, you need to select an automatic machine with such characteristics.If an RCD is not installed on a boiler, then buy a modular RCD (preferably not electronic, but electromechanical) with a trigger for a current leak of not more than 30m. The rated current of the machine in this scheme should not be higher than the rated current of this RCD, it is even desirable that it be below. For example, if I connect a boiler with a capacity of 2.5 kW, I use the VVGNGU 3×2 cable.5, two.pole automaton C16A, RCD 16A/10MA, or 16A/30MA depending on the situation. You can use a difavtomat C16A/10MA, or C16A/30MA instead of an automatic machine and an RCD.

Now I will briefly talk about the role of the magnesium anode installed in the boiler.It is needed to take the wandering currents to the ground, which appear in the boiler, preventing the corrosion of Ten and Back and the prevention of intensive fraction of the cape of Ten and the Boiler tank. It fully fulfills its function only if the boiler housing is grounded according to PUE (see above). As the anode destroys the anode, it must be changed and the tank is cleaned from the scale and everything that has accumulated in it. When the anode is completely collapsed, the heating ward and the boiler tank will begin to collapse and intensively grow in a scale. The heater overgrown with a scope will overheat due to the fact that the scale will interfere with the transfer of the heat of the heater and burn. Therefore, it is necessary to change the anode in time, avoiding its complete destruction and periodically clean the tank from scale and everything that has accumulated in it. The new anode will cost cheaper than the new heater and, especially, a new boiler.

Crazy, regarding the choice of a rating of the UZO leakage current: when choosing a setting of the UZO leaking current, it is necessary to remember that it should be at least 3 times more than (working TOK0.4 DINLY Line0.01) (SP 31-110-2003). That is, in the case of a boiler 2 kW and current, respectively, 9.1A, as well as with a line length 10 meters, the leakage current will be 9.10.410.01 = 3.74 mAh. 3.743 = 11.22. That is, on a boiler of 2 kW, the rating of the TRASE current of the RCD should be at least 30 mA.Well, in general, on such powerful devices you need to put 30 mA, of course. Washing, boiler, dishwasher, etc.P….RCD 10M should be put on wet rooms on other sockets and lighting

I agree. RCD 16A/10ma ​​I installed as much as 1 time. On a boiler 1.5 kW. The length of the line from the RCD to the heater is about 3 meters. Works. I mainly leave the standard RCDs that are installed from the plant on the boiler cord near the fork. They have parameters 16a/30ma. And in the store on sale I see an RCD only 16A/30m. Therefore, I usually put them in the event that it is possible to convince the customer. Usually no one wants to buy an RCD for an incomprehensible reason even if there is money for it.

Schemes of electrical communications

The main rule of placing powerful consumers in the bathroom is their inclusion through the RCD. A separate machine to put on the washing machine and the water heater is also required. The diagram of the possible connection is presented below.

When installing a new electric bathroom circuit, you can use both overhead and built.in electrical products. According to the PEU, you can lay the external wiring if you do not plan to start the repair in the bathroom, or last the walls and hide the cable under finishing materials.

Work with pipelines of various types

The water heater connection scheme to the water supply in the apartment and the choice of tools and materials also depends on the type of pipeline.

Polypropylene pipelines

To work with polypropylene pipes, a pipeline and a special soldering device will be required. The tees in this case are selected from a similar material, and MRN couplings are used to connect them with taps.

Polypropylene coupling with metal thread

The process itself is not difficult if the pipes are open, with hidden communications, the process is complicated by the need to open the upper layer above the pipes. Only after that it will be possible to crash into the water supply.

Pipelines made of metalloplasty

Metal.plastic pipes are usually laid on the surface, so the probability of complications is excluded. Installation is carried out using fittings, while their choice is quite large, so any water heater installation scheme can be implemented without additional problems.

The insertion is carried out using tees, to which, depending on the location of the communications and the installation site of the heater, additional pipes or directly flexible hoses are connected to enter.

The photo shows the option of how to install a water heater with your own hands using metal.plastic pipes and compression fittings

Pipelines made of steel

Apart without welding when working with a steel pipeline will allow the original “vampire” tee of the “vampire”. Structurally, it is a clamp with a removal that is worn on the pipe (of course, before starting the installation, the water supply should be blocked) and fixed with clamping screws. A rubber gasket is used for the fitness density.

The use of a repairbone repair clip is a fairly simple way of installation, but not the most reliable

Important: Before installing the three-tanks, the pipe section for it should be cleaned from dirt, rust, paints.

After installing the clamp with the removal through the latter, the hole is mainly drilled in the pipeline. To perform such work, the use of a protective sleeve is required. It will prevent damage to the internal thread during drilling. A faucet is installed on the tape thread and then. the supply hose to the boiler.

If you want to know how to solder polypropylene pipes with your own hands. the video will show the whole process, and text information in the article will help to avoid errors.

We talked about how to connect metal.plastic pipes with our own hands in a separate material.

And how to connect a washing machine yourself can be found out from this article.

Preparing to connect

The best option for installing a boiler is a bathroom. If, due to limited free space, it is not possible to install a boiler in this place, then you should choose a place in the kitchen or in the utility room. When choosing the installation site, you should take care of the possibility of summing up the 220 V and cold water supply network.

The boiler is installed at a considerable distance from the floor. In most models, the connection of communications is carried out from below, so the device should be placed at a height of at least 50 cm. If the boiler connection is performed in the bathroom, then it should be placed from the bath and sink at a distance of at least 1 meter.

Thus, the likelihood of a water device enters the surface of the device and the possibility of electric shock in the event of a malfunction of the device is excluded.

It should be borne in mind that a boiler filled with water has a significant mass and must be reliably fixed. Usually installed water heaters on the wall. For the correct location of the mounting holes, you can use a very simple way of marking. It is necessary to prepare a sheet of cardboard and marker.

Measurements are carried out in this order:

In most models, the connection of communications is carried out from below, so the device should be placed at a height of at least 50 cm

For the correct installation of the boiler, you will need to install a separate outlet and carry out cold water to the device.

To do this, you need to prepare the following materials and tools:

  • Peorator or shock drill.
  • Passatigi.
  • A hammer.
  • Socket
  • Anchor bolts.
  • Electric cable with a core diameter of at least 3 mm.
  • Spanners.
  • Screwdriver.
  • GIPS construction.
  • Automatic circuit breaker 20 A.
  • Chisel.

Connection rules

The device must be installed in such a way that it has access to it from all sides for technical work

First of all, it is necessary to take care of the electrical safety of using this device: connect to the electric power supply to the grounding wire.

It is recommended to connect a boiler in a euro.outlet, the grounding contact of which is reliably connected to the grounding of a home power grid. It is strictly forbidden to connect a boiler through an extension cord of any type and structure.

To install the water heater, it is necessary to use only factory fasteners, which are included in the kit of the electrical device.

The device must be installed in such a way that it has access to it from all sides for technical work. The distance from the side wall to the boiler is installed at least 200 mm.

If water from an individual source, such as a well or well, enters the water heater, then a rude water cleaning filter must be installed in the water intake system.

The boiler is installed only on a solid vertical surface, it is forbidden to install the device on various partitions of wood and drywall.

Mandatory to the supplying line of cold water and a removal with a heated liquid, shut.off elements in the form of ball valves are installed. This location of the cranes greatly simplifies the repair work that can be carried out during the operation of the water heater.

When connecting the boiler to the water supply, the check valve must be installed. This device will protect the formation in the water heater of the excessive pressure of the liquid, even in the case of the automatic relay failure, which controls the inclusion of the heater at a given temperature of the water heating.

An elastic tube should be connected to the opposite cranes, which is used to pull excessive pressure into the sewer.

In order to exclude the likelihood of leaks during operation of the device, it is necessary to use rubber or silicone gaskets.

When installing a water heater in the bathroom, its installation should be no closer than 1 meter from the bath or sink.

Placing a socket in the bathroom should be in such a way as to exclude the likelihood of getting water.

Elements and details for connecting a boiler to electricity

Multicooks and pressure cooks

The multicooker is another serious consumer of energy (600-1500 W), but at the same time it is good that it can work for a long time unattended. That is why it is worth making sure that it is reliably connected to the outlet, and not inserted into the extension cord with the kettle, toaster and other devices. In the case of poor contacts, heating and failure of the extension cord, adapter/tee and plug of multicooker are possible, in the worst case, the device may occur.

If there is a need to connect a toaster, a microwave, and a slow cooker through an extension cord, do not turn them on at least at the same time, use either a toaster or only a multicooker.

Hair hands and tongs

For the work of hairdries, forceps for curling hair and ironing, a huge amount of electricity is required. In fact, to prevent the operation of the circuit breaker, any devices must be connected directly through the outlet. And in the instructions for the safety of these devices (which, alas, it reads a small percentage of users), it is indicated: it is necessary to include devices directly in the outlet, avoiding extension cords and adapters.

A portable heater (reflector) is one of the main perpetrators of fires. Both the heater and the air conditioner are designed for cyclic inclusion and off while working, and each time they turn on, they consume a lot of electricity. This can lead to overload of the extension cord and either automatic shutdown will work, or the extension cord may overheat. For this reason, devices should always be connected to a stationary outlet.
