Is it possible to install a wall water heater on the floor

Vertical and horizontal boilers, comparison and differences, which is better in the available conditions of the house

The accumulative water heaters of the horizontal and vertical installation method have the same principle of action, power ranges, capabilities, varieties of materials.

Selection of the type of placement is carried out as usual with the following parameters:

  • stainless steel;
  • steel with an internal coating of glass ceramic (fiberglass, biosteclopher) or titanium spraying;
  • plastic.
    , closed (do not contact with water, in the casing);

  • Wet, open, submersible (in contact with H₂o, corrode faster);
  • To save electricity and amenities, there are boilers with two heaters.
  • magnesium;
  • “Eternal” (titanium, aluminum, zinc).
  • thermostat;
  • antibacterial coating;
  • anti.measurement;
  • overheating protection relay;
  • mechanical or electronic control;
  • turning on/off programming;
  • thermometer, temperature board (mechanical, digital);
  • heat holding mode: the tank works like a thermos, first the heating water heats the water, then it turns on only to maintain a certain temperature.

Horizontal boilers

Places of water heaters (bathrooms, bathrooms) are usually small, several square meters. The form of the premises also has restrictions, requires the ergonomicity of the device. Under these conditions, the horizontal container is better.

When it is appropriate to install horizontal storage electric boilers:

  • The vertical tank of the desired volume is not placed due to the lack of a place or geometry of the room;
  • It was decided to save a place for users (in showers, bathrooms, bathrooms, this is relevant) or for other equipment, for example, hanging a boiler at the top of the room;
  • Aesthetic preferences: placed in the niche along the ceiling compact, flat boiler Mene noticeable.

Pros and cons of horizontal boilers

Lack of horizontal electric boilers one. With the same technical parameters with a vertical type, due to the structural differences associated with the position of the container, they are heated more slowly, which is associated with the method of mixing water of different temperatures (incoming and already heated, contained in the tank).

How does the horizontal of the body affect the operation of the water heater:

Element, shape of the contents Description
Ten In the vertical capacity, the placement of the heater is more effective, the action covers a significant amount of contents. In the horizontal case on the sides of the fluid heater, it warms up slower.
Water volume Horizontalness is less than effective mixing, heat spread.
Pipes, entrance/output nozzles The location and a small interval between the connections determines the rapid mixing of different.test layers, which creates a delay in warming up. This is especially noticeable if the pipes are located not from the side, but from below.

With a horizontal position of the capacity, the contact area of ​​the outgoing hot fluid and the incoming cold increased (maximum possible), mixing of different.test layers intense, so fast, so already heated water is cooled faster.

This disadvantage is relative, only with very active use, when mixing occurs continuously. The temperature of the already warm layer drops in accelerated mode, which is noticeable, for example, when the already heated water came out of the container, not having time to fill the bath, after which the liquid is slightly cooler.

With normal consumption of the delay in heating there is no. In other parameters, the quality of work does not differ in any way. Additionally reduces to zero a lack of mixing protection, which all high.quality water heaters have.

The cutter does not allow the input cold stream to beat vertically, lays it below, where it warms up with a heater. A well.heated layer remains at the top, the temperature of which is little affected by the incoming fluid. Therefore, you should not refuse to install horizontal electric buses if it is convenient in existing conditions.

Pros of accumulative water heaters of horizontal performance:

  • A flat compact form allows you to install in narrow niches, closer to the ceiling;
  • You can mount the tank both near the ceiling and on the floor, that is, the range of places expands;
  • Water eyeliner can be located on the side or below;
  • Aesthetics. the device may look like an attractive rectangular item with a digital scoreboard suspended above the door to the bathroom;
  • The size of the horizontal boiler can be selected larger: when installed under the ceiling, the tank will not take the beneficial space as a vertical design installed closer to the floor.

Popular models of horizontal boilers

A selection of horizontal water heaters popular in the market:

  • Timberk SWH FSL2 80 He;
  • Polaris Vega IMF 80H;
  • Thermex Flat plus if 50h;
  • Thermex Champion Silverheat Ers 80 H;
  • Electrolux Ewh 100 Royal H.

The best place for mounting

Many place a boiler in the bathroom over the toilet or other side surface. Such a choice may entail a decrease in space in the room, complicates the functionality of the room. Nevertheless, the best option for attaching the device will be a place over the bathroom itself or near the shower cabin.

Additional nuance of placement

There are a number of secondary features that will affect the location of the device. When choosing a place, it is also worth considering the following nuances:

  • No need to remove the device from the pipes of water supply too much in order to reduce the water supply distance and hide the communications;
  • It is desirable that the boiler is located as much as possible from the point of water flow;
  • It is recommended to leave free space on the wall near the boiler in order to organize free access to the device in case of correcting the breakdown.

If all these nuances are observed, then there will be no problems with the functioning of the device.

Pipe reinforcement for the installation of a water heater

Let’s dwell a little at the pipe fittings that will be required when strapping a boiler.

Security Group

To protect the water heater from hydraulic network overload, manufacturers recommend installing special reinforcement. a security group that has a pressure limiter. If the pressure in the network exceeds 4.5 atm, before the security group you need to install pressure gear or a reduction valve.

Safety group for water heater

Common Water Heater Myths Answered | Ask This Old House

For small capacitive water heaters, this element is desirable, but not required.

Securder valve

The safety check valve is designed to guarantee the full filling of the tank with water, otherwise heaters can be exposed and burned out. Dragging water from the tank is possible when pressure begins to drop in the highway, and the valve will keep the water in the container. The second function of this valve is to drain water from the tank, for example, for its repair. The third function. protection against tank rupture. Sometimes thermostats fail, water continues to heat up, the pressure in the tank increases. If there is no water selection during this period, then the tank can be depressurized under the influence of boiling water and steam. Fortunately, this rarely happens, but it is better to take security measures, especially since the price of this valve is not comparable with the possible consequences of the accident.

Safety valve

If the valve is not installed or is unusable, you will immediately find out about this. hot water will flow from the cold crane. Hot water will also be in the toilet tank, and you will pay for the electricity consumed for this heating. It is installed at the input of cold water into the water heater of the capacitive type.

Advice! The arrow on the case shows the direction of the water current. When installing the boiler under the sink, the direction of the cold water flow. down, which means that the discharge for drainage will be directed upward. So that the water does not drip to the floor, install a drip funnel under it with the drainage of the drain into the sewer or put the tube of suitable diameter on the nipple and lower it into the container.

Other valves are designed to block cold and hot water on each of the branches of the water supply.

Attention! The water heater installed under the sink is hidden from the eyes, and the leak can not be seen immediately. Therefore, all water supply compounds should be sealrated qualitatively, sealed, for example, linen ribbons, fum tape, special paste.

Installation of a water heater for a sink

Installation of different types of heaters is slightly different. Consider the connection schemes and the installation procedure for various water heating structures.

Installation of a unpaired water heater

The easiest way is to install non.pressure boilers. They cannot be connected to a conventional mixer, connected directly to the main pipeline, since the device is not calculated on the network pressure. it can be broken off.

A special mixer for such a boiler has two valves. one regulates the temperature (mixed with cold), the other consumption. In this system, the mixer performs the function of the security group: it blocks cold water at the inlet to the heater and dumps excess water that occurs due to its expansion as a result of heating.

Mixer for non.storage heater

Usually, when buying such a heater, there are tubes and locking valves that are installed at the entrance and exit from the tank. The check valve in this case can not be mounted (due to the lack of risk of pressure jump) or replaced simply with a check valve. The floor heater is simply installed on the floor, and the wall should be fixed to the brackets or other mounts included in the kit. Then the tubes are connected according to the scheme.

Ignoring flow water heater is mounted according to the same principle. We connect the heater to the mains only after filling the water heater with water.

Installation of a pressure storage water heater

Take care in advance about the presence of a socket with a ground contour near the heater. If the heater is wall, march on the wall of the hitch, drill holes for fasteners, fix the bracket and burn the heater. The floor heater can not be attached to the wall.

We begin the preparation of the water heater. To do this, we perform the following:

  • To supply cold water (blue mark on the tank fittings), we mount the check valve in the check valve. The direction of water on the valve is indicated by the arrow.
  • On both bark fittings, we screw locking valves. On cold water, the shut.off valve is installed immediately on the valve.

Attention! You do not need to pull the thread too much during installation, you can disrupt!

  • We connect a flexible eyeliner to the valves (may be included) or through adapters of metal.plastic (polypropylene) tubes with a diameter of 16–20 mm for connecting to the water supply. The latter method is preferable, since it is more reliable and, in addition, a larger diameter of the pipes provides less hydraulic resistance and better water supply.

Next, we work with the water supply. we mount the tees at the water.clearance point after locking cranes (which are at the entrance of the pipes to the apartment):

We connect the hoses (tubes) coming from the tank with the corresponding pipes of hot and cold water. Check that it is the cold to the cold, and hot with hot.

Connect a dropper or siphon for draining into a sewer or a thin pipe for draining to a separate container to the drainage valve pipe.

Before turning on the water heater, redraw the hot water crane on the highway. Connect the electricity only after filling the tank with water.

Installation of a pressure running heater

The installation of a flow water heater is similar to the installation of the heater of the accumulative. The difference is the absence of a reverse safety valve in view of the absence of a tank. For some models, it is recommended to install a filter of rough or thin cleaning and even a softener of water on the supply of cold water. The device is attached to the wall, cut with tubes with shut.off valves into a high and cold water line after network valves and connected to the mains.

Most of the running heaters, especially high power, are not equipped with an electric grinding. It is assumed that the connection of the equipment should go through a selected fishing line for a trimmer directly to a separate machine in an electrical panel. A trimmer fishing line should be grounded, with a short circuit protection device. The cable section is selected depending on the power of the flow boiler.

Dimensions

The sizes of water heaters depend on their type. Proporal models always have a much smaller size compared to accumulative. Proporal can be in size from 190 mm by 150 mm to 300 mm by 200 mm, while accumulative. from 420 mm by 900 mm to 600 mm by 1200 mm. The latter dimensions depend on the water tank. It can have a container of 30 to 200 liters.

DIY selection and installation

Before purchasing and installing a water heater, it is necessary to decide on the choice of a suitable device.

  • hot water consumption;
  • the number of points connected to the system;
  • use modes;
  • The main characteristics. type, volume, power, performance;
  • shape and material;
  • Installation method.

Only after all the parameters are defined, you can safely go to the store for buying.

Before starting work on installing and connecting a water heater, it is better to prepare all the necessary tools:

  • roulette;
  • Peorator or shock drill;
  • fasteners;
  • divorce and ordinary keys, as well as pliers;
  • tees for connecting to the water supply;
  • locking taps;
  • sealants;
  • Flexible hoses.

And it is also worth taking into account the features of the connection, such as building pipes, stroke. In this case, it is also worth it to purchase materials in advance. In addition, the connection of the water heater depends on the type of pipeline in the house or apartment.

10 TIPS to avoid Pipes and Cables in Walls (shorter version)

  • Polypropylene pipeline. To work with it you will need a soldering device and a pipeline. All connecting devices should be purchased from the corresponding materials. In the case of an open pipeline, the work will be completely simple, if the communications are hidden, you will need to open them.
  • Metaloplasty pipeline. This type is usually not hidden, so the work will be easy. Fitting is used for installation, their choice is very extensive, so there will be no problems with the purchase.
  • Steel pipeline. For work with this option, you will need a welding machine. But you can also use a special “vampireus”. This is the same clamp worn on the pipe and fixed with screws. For sealing, you need to use a rubber laying. After installing it, a hole is made in the pipeline. The tap and hose suitable for the water heater are installed on the allotment.

And it is also better to draw a water heater connection diagram and indicate the connection points to the water supply.

Immediately before installation, you need:

  • free up and prepare a place for installation;
  • make sure that the wall is quite strong;
  • make sure as a wiring, as well as choose the right for installation;
  • verify the operability of water pipes.

For unmistakable installation, it is necessary to study the instructions for the water heater. Immediately before installation, it is necessary to block the water, and also turn off the electricity. To connect high.power devices, a three.core wire made of copper with a thick cross.section of the wire, a meter by at least 40 A, an outlet with grounding, automatic and island will be additionally necessary. Much attention of the fortress of the wall must be paid when installing overall boilers. When installing it, anchors and especially strong hooks are used. It is more convenient to place devices with a volume of more than 200 liters on the floor.

It is better to install a pair with an assistant to facilitate the process. The installation of running and accumulative devices is carried out in a similar way.

The first step is the installation on the wall.

  • It marks the lower fishing line for the trimmer of the boiler installation. Next, the distance to the fastener is measured. With special care, you need to approach the marking of the upper boundary so that the top of the water heater does not rest against the ceiling.
  • Next, you need to make holes for fasteners. For concrete and brick, you will need an electric drill with a winning drill. For wood it is possible to use the usual. The diameter of the tip should be less than the diameter of the dowel.
  • Then you need to drive two dowels in parallel, tighten the anchors and hang a water heater.

The second stage is a water supply connection. Using flexible hoses or plastic pipes, you need to connect the device to the water supply. The use of polypropylene pipes will cost more, and the work will be more difficult. Next, it is necessary to insert the pipes into the main water supply. When connecting the boiler, you need to pay attention to which pipe to connect to cold and which to hot water. They are marked with flowers. blue for cold, red. for hot water.

On a pipe for cold water, you need to put a special check valve, which dumps increased pressure. This occurs automatically and prevents the breakdown breakdown. If there is no such valve in the kit, it is better to purchase it yourself. To install it, you need to wind one of the ends for better isolation and connect it to the valve. The other can be left without sealant and screwed to the pipe.

When installing a flow water heater for rare use, it can be connected to a shower hose. And only cold water is connected to the unit itself.

Tankless VS Tank Water Heater3 Myths DEBUNKED!. Twin Plumbing

  • block the water supply;
  • cut the pipe;
  • Cut the thread;
  • wind the seal;
  • connect the tee;
  • put a crane;
  • connect to the boiler with a flexible hose.

Tools necessary for work

You will need: for the installation of a water heater:

  • instructions with a description of the connection;
  • pencil;
  • metal hooks;
  • dowels and screws;
  • roulette;
  • construction gun;
  • Peorator or drill;
  • hoses;
  • network cable;
  • water.cleaning filter;
  • nozzles.

Clarification regarding the hoses for supplying water to the unit: better, but more reliable. Flexible products can fail ahead of schedule. It is desirable if the elements for bringing pipes are copper.

Installing a boiler in a private house, in an apartment or in the country is a reasonable solution to provide hot water with the required rooms. The installation of the device can be entrusted to specialists, as well as if you have the necessary skills, the installation of a water heater with your own hands will not cause difficulties.

Types of boilers

There are several types of boilers, and how the water heater will be installed depends on the design and type of unit.

  • An indirect heating unit. They do not have heating elements, and the liquid in the tank can heat up from external sources (heating systems, using a solid fuel or gas boilers, heliosystems, using solar panels). The devices can be both wall and flooring (the container can reach up to 1000 liters, and when installing them you have to put on the floor).
  • Gas storage boiler. This type of apparatus should not be confused with gas columns, in essence, which are fluid heaters. Water in the gas unit is warming up by combustion of gas and is in a special tank. DIY boiler installation is not recommended due to the fact that gas connection should be carried out by specialists. In addition, you need to provide a good hood for burned gas products.
  • Electric storage unit. Electric boilers are most popular. The liquid in them is heated using the heating elements installed at the bottom of the tank. The temperature is regulated by the built.in thermostat. On the example of the Termies water heater, you can see that there is also electronic control of heating fluid in the aggregate. Electric devices have compact dimensions and are easy to install and connect.

Manufacturers of water heaters under the sink

When buying, it is recommended to pay attention to the country manufacturer. As a rule, Chinese production is the most economical option, but after a small amount of time it will take to replace the main parts, which will lead to additional expenses. Such firms are producers Polaris, Ballu. However, it is these economical options that turn out to be the most popular today. The models of German, Swiss or domestic production, such as Thermex, Electrolux, Aeg, Gorenje, are more reliable.

In most cases, all the materials necessary for installing and connecting such equipment are included in the kit. If necessary, the missing elements should be purchased before starting installation work. For example, in many budget models there is no check valve.

Set the desired water temperature and connect the heating elements of the water heater only with the full filling of the tank.

Water heater for the sink is the best option for small rooms. The type of equipment, capacitive or flowing, is selected in accordance with the purpose of the device and the number of consumers. The installation is simple, but if a person has never dealt with plumbing equipment, it is better to entrust the work of qualified masters.

A water heater installed under a kitchen sink or shell in the bathroom helps to save space in the conditions of small apartments and does not violate the aesthetics of the room. Let’s look at the types of boilers that can be installed with your own hands, deal with reinforcement and installation stages to avoid common mistakes.

A water heater that is installed under the sink can be a constant or backup source of hot water in the kitchen. there is always a place there, and it does not interfere with anything. Which boiler to choose and how to install it correctly?

Types of water heaters for installation under the sink

Since the place under the sink is nevertheless limited, you can install there either a cumulative small water heater with a volume of 10–25 liters or an flow. Heating in them is carried out by open.type electric heaters or hets. Gas boilers are usually more productivity and are made only for standard wall installation.

Heaters differ for installation under the sink by the location of the pipes supply. upper. When buying a heater, it is necessary to pay attention to this, otherwise the installation device installed under the sink will work poorly and not for long.

So which water heater is better. accumulative (capacitive) or flowing (pressure)

The accumulative heaters occupy more space and are more expensive, but the power they consume are lower than in running (up to 3 kW), and they can give a larger volume of hot water per minute.

Since the flowing water heater has a relatively high power for domestic consumption. up to 8 kW, you need to make sure that the electric network in an apartment or house can provide it without constant “knocking out” machine guns. If the heater is intended only for the duration of the heating network of crimping, when in the summer hot water is turned off for 2 weeks, then heating 2 l/min will require a power of not more than 3.6 kW. Cold “winter” water will not be possible to heat to such a volume even to 30 ° C. For year.round consumption, or a capacitive water heater or high power flowing.

With the initial turning on the accumulative device, it will take some time for water heating, flowing can immediately heat from 1.8 to 4 liters per minute. They immediately heat the entire stream of water, while the accumulators warm the incoming cold water, which is mixed in a tank with hot water when it consumed and after a while the temperature of the water in the tap begins to decline.

That is, both types of water heaters have both advantages and disadvantages, and choice in favor of one of them is only a consumer preferences.

But for a country house, in the absence of a main water supply, an indispensable water heater is indispensable, which is equipped with a special mixer of a small diameter to obtain a stronger stream. To create pressure, it is equipped with a hydraulic pressure relay. If the cottages are not used in winter, it can even be removed, and in the spring it is installed again. so its installation is simple.

Pipe reinforcement for the installation of a water heater

Let’s dwell a little at the pipe fittings that will be required when strapping a boiler.

Security Group

To protect the water heater from hydraulic network overload, manufacturers recommend installing special reinforcement. a security group that has a pressure limiter. If the pressure in the network exceeds 4.5 atm, before the security group you need to install pressure gear or a reduction valve.

Safety group for water heater

For small capacitive water heaters, this element is desirable, but not required.

Securder valve

The safety check valve is designed to guarantee the full filling of the tank with water, otherwise heaters can be exposed and burned out. Dragging water from the tank is possible when pressure begins to drop in the highway, and the valve will keep the water in the container. The second function of this valve is to drain water from the tank, for example, for its repair. The third function. protection against tank rupture. Sometimes thermostats fail, water continues to heat up, the pressure in the tank increases. If there is no water selection during this period, then the tank can be depressurized under the influence of boiling water and steam. Fortunately, this rarely happens, but it is better to take security measures, especially since the price of this valve is not comparable with the possible consequences of the accident.

If the valve is not installed or is unusable, you will immediately find out about this. hot water will flow from the cold crane. Hot water will also be in the toilet tank, and you will pay for the electricity consumed for this heating. It is installed at the input of cold water into the water heater of the capacitive type.

Advice! The arrow on the case shows the direction of the water current. When installing the boiler under the sink, the direction of the cold water flow. down, which means that the discharge for drainage will be directed upward. So that the water does not drip to the floor, install a drip funnel under it with the drainage of the drain into the sewer or put the tube of suitable diameter on the nipple and lower it into the container.

Other valves are designed to block cold and hot water on each of the branches of the water supply.

3 MYTHS About Tankless Water Heaters

Attention! The water heater installed under the sink is hidden from the eyes, and the leak can not be seen immediately. Therefore, all water supply compounds should be sealrated qualitatively, sealed, for example, linen ribbons, fum tape, special paste.

Peculiarities

The floor water heater will harmoniously rise where it is impossible for some reason to install a wall heater. The case can be associated not only with the lack of enough space, but also with the special design of the walls themselves, which are not able to withstand the load from hundreds of liters of water. over, situations regularly arise when another way to warm the water, except for the installation of the heater on the floor.

The traditional wall circuit involves the connection of the water supply and the electric wire below, from the same side, access to working elements is also provided. But in this case, the designers have to place any mounting parts from the side.

The facade of the floor product is used to accommodate electronic components, and the water will enter and leave to enter the back. This significantly increases the aesthetic qualities of the structure and helps spatially separate the cold flow from the hot. Leading firms invariably equip their heaters with special supports, although these legs can also represent part of the body.

In most cases, three legs are put at once, this helps to avoid loosening the product. The remaining differences are due to the approach to the construction of a certain model.

The floor electric boiler varies primarily in terms of the volume of the tank. So, when the tank accommodates 100 or 200 liters of liquid, there are no special differences in installation compared to the wall device. Unless those devices that are equipped with legs will be easier to try on and use in work. But such heaters are suitable only for purely domestic purposes, commercial products are produced by a minimum of at least 300 liters. Separate specimens contain up to 1000 liters of water.

This is natural in the size of the apparatus. But not only. even if there is enough space, connect a large unit to the home power grid, it will absorb too much current. And installation will already be difficult, require special design. It is important to clarify: 100 l is the minimum container. The only exception is kitchen boilers with a volume of 10, 30, 50 or 80 liters.

The purpose of using such devices is not a full water supply, but just providing hot water for culinary procedures. But it is important to understand that in fact, such heating heaters cannot be considered, initially they are designed for a wall installation. Boilers should be clearly distinguished, which are placed under the sink and above it. outwardly, such devices are very similar. In any case, if it took water heating in a significant volume. 150 or 400 liters, you will have to choose a fully autonomous apparatus. Under the sink, it is no longer to put it.

As for manufacturers, the products of Siemens, Valiant and Ariston are best manifested in the best way. Indicates the quality of such options at least that they are in demand even in European countries.

Thermex products are not recommended to purchase. It is assembled in the basis of Chinese components, although it is intensely issued for the German product. This is at least suspicious.

If you need to cook a large amount of water, the best solution is often not a boiler with a built.in tank, but an indirect heating boiler. It is such systems that have the most capacious tanks. The built.in secondary heat exchanger produces heating in the water container due to the receipt of the already heated liquid. You can use water energy from the central heating system for heating, that is, to refuse to consume electric energy, natural gas or other types of fuel. The advantages of indirect heating are also associated with the following moments:

If an ordinary double.circuit boiler provides hot water only when it works, then the drive for several hundred liters with thorough thermal insulation can cool for several days. Even in case of accidents on gas pipelines, in the mains or on the central heating line, hot water supply in the house will be provided. A more perfect option implies a combined heating scheme. It provides for the use of additional heater inside the tank. Models with a built.in thermostat cannot overheat, and at the same time additional consumption of current does not provide a significant load on the personal budget.

According to experts, in order to confidently supply with hot water 3-5 parsing points (that is how much in most private houses), there is enough drive with a volume of 150 liters. Another 50 liter should be added for cottages with a pair of toilets. Such norms allow residents and guests to fully use the benefits of civilization, not feeling anywhere deprived. Put floor gas speakers, unlike storage systems, is not recommended. 3-4 years will pass, and due to the wear of rubber membranes, they will serve either very cold or overheated water in the first moments.

Tips and recommendations

The mechanical management scheme is justified only for the sake of strict savings when buying. But the additional automation fee pays off, given the benefits of the thinner setup. It is very important to think through the competent installation of the system. Otherwise, even good heating units will change the heating temperature depending on the pressure in the water line. When there is no experience of solving such problems, it will be more correct to seek help from professional installers.

It is important to check that the water heater has all the security funds, which include:

Even a negligible probability of boiling and explosion should not soothe. If the heater is connected to the central heating system, static pressure regulators must be mounted. They will help prevent his growth for a critical mark and probable damage to the tank. Gas devices manifest themselves when supplying hot water in an apartment building, dormitory or hotel no worse than electric counterparts. There are two main formats for the execution of the furnace. open and closed.

Combined boilers are especially beneficial if the connection is used at night (at a reduced tariff). In this case, it is worth choosing structures with software control, which will ensure hot water just in the morning, when it is needed. The most modern (and expensive) types of control systems can be activated even remotely, using SMS. Indirect heating boilers are well combined not only with electric or gas heating, but also with boilers working on solid fuel (pellets). When the type of device is finally selected and its equipment, you need to deal with the installation features.

In some cases, the entire system is mounted from scratch, which requires careful design and primary installation of each node. But such “freedom” is possible only in new houses or when dismantling existing nodes. often you have to adapt to already formed contours of heating and hot water supply, to previously laid wiring. These circumstances should also be taken into account when choosing a heater so that it does not turn out to be incompatible in any important parameter. Any floor water heater requires free space.

If there is such a place, it is worth focusing on areas located in the immediate vicinity of heating pipelines and water pipes. When a washing and dishwasher is used in the house, it is better not to skimp with the size. Volume of 300 liters fully justifies itself. Regardless of the type of water heater, it is advisable to supply well.filled water to it, because this will extend the life of the equipment.

Choosing electric models is justified in cases where there is no particular desire to obtain permission, to form expensive design documentation.

The low.power flow device will be the best choice for those who only want to replace full central water supply in the summer months. But when you need to put the device in a hidden version, you will have to use more expensive and complex models. The choice of a gas heater is justified if there is a connection to the main gas pipeline. If you have to buy gas in cylinders, its delivery will simply be unprofitable. If you have a choice between this option and electric power, it is worth focusing on total consumption.

Norms and requirements of the installation of a gas column

Before connecting the water heater, make sure that all the documents necessary for installation are collected. The registration procedure is as follows:

  • obtaining the results of the examination of the state of the chimney;
  • the provision of a column to the gas service;
  • manufacturing a project for connection, from those. conditions;
  • Application for the installation of a water heater.

After the approval of the project in Gorgaz, it will be necessary to prove ownership by granting a passport, documents confirming the right to own an apartment or house. After that, a permit for the installation of a gas water column will be issued.

Representatives of the Contractor will make a insert into the highway, install the counter, hang and connect the water heater and connect. At the request of the customer, the installation can be performed by any organization that has an appropriate permit and a license to carry out work of increased danger.

Premises for installing a column

Gas water heaters potentially dangerous equipment. The premises in which it is planned to install a boiler must comply with fire safety requirements, the rules described in SNiP and SP, as well as in the recommendations of manufacturers.

The main criteria and requirements for the room used for the boiler room:

  • ceiling height of at least 2.2 m;
  • there is natural, supply and exhaust ventilation, providing triple air substitution;
  • mandatory the presence of a window or an opening window;
  • total area of ​​at least 12 m².

As a boiler room, it is allowed to use any non.residential room that meets the described requirements. It is not allowed to connect a boiler in living rooms: kitchens-studios, living rooms. In rooms with high humidity (bathroom, toilet), installation is strictly prohibited.

Technical requirements for premises for the installation of flowing gas and storage water heaters may vary depending on the region. Before you start paperwork, you should ask what norms apply in a specific area.

How to hang a column on the wall, at what height

Regulating documents stipulate the installation height and type of walls and partitions, on which the installation of gas water heaters is allowed. Gaps and safe distances between the boiler and other gas.consuming equipment are indicated.

The speakers are installed at a distance from the ceiling of at least 25-30 cm. From the floor to the case is kept from 80-120 cm. Accordingly, the boiler is installed at a height of about 180-200 cm along the upper edge. Compliance with the requirement is necessary to ensure normal air circulation. The regulated height of the installation of a gas column from the floor can vary depending on the type of column (atmospheric or turbocharged).

  • The type of septum surface. PPB allow installation on a wall of dense building material with a high level of fire resistance. Below are the main types of walls and the existing nuances of the installation are described:
  • Installation in a wooden house. possible subject to additional protection. The requirement is related to the fire hazard of wood. At the place of placement of the column, the wooden surface of the wall is protected with a steel sheet and asbestos with a thickness of 3 mm. According to the PPB, fire gaps in the places of passage of the chimney through partitions and ceilings provide. A wall of wood can be closed with a layer of special plaster, 3 cm thick. Another option: prepare a place for installation by making a partition of non.combustible materials (brickwork). To hang water heaters on a wooden wall use an anchor attached to the kit. Hanging water heaters using wood screws is not recommended.
  • Plastic panels. installation of gas water heaters is prohibited. Violation leads to the refusal to put the equipment into operation. You can’t hang boilers on a plastic panel for several reasons: there will be no gap between the heater body and the wall (according to the requirements of at least 2 cm), the material is fuel and fire hazard. You can try to get around this ban. Based on the existing norms, you cannot fix the column on plastic panels, but do not bring the material to the place of the already installed gas.consuming equipment. At the same time, it is important to take care of the necessary gaps.
  • Concrete surface. material fully complies with safety standards. The exception is the reinforced concrete wall used as a supporting structure. Installation is performed on ordinary building anchors.
  • Brick wall. installation is allowed. The exclusion of partitions made of hollow brick, which is unable to provide reliable fixation.
  • Drywall wall. norms allow such placement, subject to some conditions. Drywall is not combustible, but easily amenable to mechanical effects, so in itself it cannot provide reliable fixation of the column. A boiler is hung on a plasterboard wall in a place where the surface was additionally reinforced when erecting a metal frame. Usually, to enhance the bearing capacity, a wooden beam is installed in the inside of the profiles. The wall is thrust under painting, or lined with ceramic tiles.

Installation of a combustion product withdrawal system

Gas speakers should be connected to a separate chimney channel, with natural circulation. Forced hood is prohibited. When passing through the floor slabs and the roof, fire breaks are provided. General requirements:

  • The chimney is made from a material that can withstand severe heating without deformation and burning resistant to condensate;
  • Sixions are not allowed, there should be a good fixation to the walls of the house;
  • The diameter of the pipe is determined by the manufacturer of the column, the chimney is prohibited to narrow;
  • External parts are insulated.

Frequent questions about placing a gas column

The design documentation will indicate the location of the water heater with the ability to rearrange it within the same room in the range of 1.5 m. From the original place of location. Some nuances regarding placement will have to be decided on their own, based on the current regulatory documents.

Only with proper installation of gas water heaters, their commissioning is allowed. Before starting the column, the inspector will carry out an inspection in order to identify violations committed during the connection. Based on the results of the audit in the technical passport, a seal is put on the start of work. In connection with the rules of connection, several questions arise. The answers to the most common of them are given below.

Is it possible to hide the column in the closet

Yes, this is allowed, subject to several requirements. You can close the gas column with a cabinet if:

In practice, this means that you can remove the column in a closet without the bottom. In some regions, gas workers require that the water heaters’ body is not closed to the door. By fire safety technique, hide a gas column into the cabinet, provided that the chimney will not come into contact with flammable materials. Accordingly, you need to remove the top of the cabinet.

Is it possible to put a gas stove under the column

In this case, they are guided by the requirements of the boiler manufacturer. The distance from the column to the plate is, in accordance with the instruction manual 40 cm. In old apartments, Khrushchevs, gaps often reduced to 15 cm. But in the joint venture it is stated that when placing it is necessary to adhere to the norms specified in the passport. Respectively, at least 40 cm is left between the stove and the column. Violation of breaks leads to a refusal to warranty service. The second point that prevents the column over the stove is the placement of the gas.consuming equipment indicated in the project. Non.compliance with recommendations leads to fines and disconnecting the water heater by the inspector.

Is it possible to hang a column under a gas pipe

The rules do not prohibit this, but indicate the need for breaks. There should be at least 15 cm between the column and the gas pipe.

The design documentation usually provides for the placement of a flow boiler. Installation is carried out in accordance with the laid parameters, including the distance from the column to the gas pipe. If the pipe passes above, the gap is increased to 25 cm.

Is it possible to install a column over the sink

In the old SNiP, acting up to 65 g, this was allowed. In Khrushchevs, to save space, placement over the sink, often found quite often. Although in modern construction orders such a norm is not directly spelled out, gallmakers may demand to withstand the distance from the column to the sink of at least 40 cm.

The reason for the ban is quite simple. Moisture leads to settlement and concentration of carbon monoxide. The frequent cases of poisoning and leaks lead to constant tightening of the norms. When connecting a new column, this requirement will have to be observed.

Is it possible to put a refrigerator under a column or nearby

Household manufacturers prohibit the close placement of a running gas boiler. The distance between the refrigerator and the column is determined by the gaps indicated in the equipment passport. The refrigerator will not be able to fully work and will constantly overheat if the water heater is closer than 30 cm. From him.

To ensure normal conditions, it is important to provide for the refrigerator a sufficient gap between the back of the case, where the radiator is located and the wall, about 5 cm.

Connection of a gas column is carried out in accordance with the manufactured project and the recommendations of the manufacturer.
