How to choose the correct mixer with a thermostat

Thermostatic mixer: how to choose and install a mixer with a thermostat

Two.cavalry and one.rod taps are installed on shells for mixing cold and hot water. They are extremely easy to operate and cheap.

But when the pressure changes in the pipes, their valves has to be twisted so that the flow temperature returns to the desired parameters. It would be nice to automate this process, is it so?

The modern thermostatic mixer allows you to level this small but annoying inconvenience. The range of models from various manufacturers is so rich that it is quite difficult to choose the right option. You are difficult to choose? Or decided to independently install such a mixer, but afraid to break something by chance?

The principle of work of a household mixer with a thermostat

Changing the pressure and temperature in the pipes of water supply is an unpleasant situation that residents of both apartment buildings and private cottages face. This is especially pestering in the morning, when a jet from the crane in the washbasin becomes too hot, then too cold.

This happens due to the fact that everyone in the house at this time begins to intensively use water for washing and bathing. Its consumption increases sharply, causing pressure drops.

The main task of the thermostatic mixer is to obtain in the spout the water flow unchanged in the temperature for consumption in the washbasin or the soul

According to domestic standards, the temperature of the hot water in the centralized system can range from 50 to 70 degrees. The scatter is large enough.

For public utilities, this is good, they may not be very worried about going beyond the boundaries of standards. And consumers are forced to suffer from inconvenience. You have to mount special control devices or constantly adjust the water supply in the tap.

Here, the fairy-resistant mixers come to the rescue, all models of which are divided into three categories:

The former are the simplest and most affordable in price. The adjustment in them of the required temperature and pressure of the water is carried out by means of a lever or valve, and maintaining the specified parameters. due to pure mechanics and changing the physical properties of the internal elements of the device.

The second and third already have electronic components that require constant energy.

Type #1. mechanical adjustment devices

The functioning of the mixers of this type is based on the movement inside the device of the movable valve, which reacts to the change in the parameters of the mixed water jet.

If the pressure increases in one pipe, then the cartridge simply shifts and reduces from another stream coming to mix water. As a result, the height temperature remains at the same level.

The mechanical mixer has two regulatory heads: the right with a red-blue strip for setting temperature and left with the designation “On/OFF” to control pressure

The internal moving valve contains a material that sensitively and quickly reacts to all changes in the temperature of the water that falls into the mixing device.

In most cases, synthetic wax acts as a sensitive sensor-termeemelon. Under the influence of temperature, it compresses and expands, which leads to a displacement of a locking cartridge.

Many mechanical models have a fuse on a control valve that limits the maximum temperature at 38 ° C. For humans, such indicators are considered the most comfortable.

But even in the absence of a fuse, hot 60–65 degrees water from a thermostatic mixer will not flow. Everything is calculated so that when the indicated temperatures reaches the wax expands to the maximum, and the valve overlaps the DIS pipe. completely. Burns from boiling water are excluded here by definition.

Using a mixer with a thermostat is a guarantee of comfortable and safe bathing even the smallest children, its surface is never hot

Valve displacement occurs almost instantly inside. Any change in the temperature of the incoming water or its pressure leads to an immediate expansion/narrowing of the thermo element.

As a result, even strong fluctuations in the parameters of the flows in the pipes of the hot water and the CHS do not affect the general jet in the spout. From it, water will flow exclusively with the indicators set by the user.

In some models, instead of wax, bimetallic plates are used. The principle of their action is similar. Under the influence of temperature, they bend and move to the desired depth of the valve.

Type #2. Electronic filling devices

Electronic thermostat mixers are more expensive, more difficult in technical terms and require power supply. They are connected to a socket through a network adapter or have a battery in their composition, which is subject to regular replacement.

The control of an electronic thermostat is carried out through:

Water indicators in this device are controlled using electronic sensors. In this case, all numbers are displayed on a special liquid crystal screen. Both temperature and pressure are often displayed on the display. But the option is possible with only one size.

The outer panel is very convenient for monitoring the device: a small screen allows you to see the exact parameters of the water current from the thermostatic mixer

Often in everyday life, an electronic mixer-a-tank with a display is a device with excessive functionality. Such equipment is more intended for installation in medical institutions or other public institutions.

It is much more common in showers and toilet rooms of office buildings than in kitchens or in bathrooms of private cottages.

However, if it is planned to build a “smart home” with all kinds of gadgets simplifying life. then the mixer with an electronic thermostat is precisely what is required. It will definitely not interfere in such a dwelling.

In addition to automatic control of the temperature of water for greater comfort in the bathroom, you can equip a warm floor. In order not to depend on the mood of heat supplying organizations in the cold season.

What are the mixers with the thermostat for its intended purpose

The differences in the mixers with the thermostat are mainly in the purpose of the models. Namely:

Such models do not have pouring and switching a bath/shower. They are intended only for connecting a hose with a shower watering can.

Unlike shower mixers, they have a short non.rotary excess, the ability to switch shower/bath mode and the ability to connect a shower hose.

Just like a bath mixers with a shower have a bathtub/shower and the possibility of joining a shower hose, but differ in a long swivel spill.

These are compact.sized thermostatic mixers with a fixed surge. Can be installed on the countertop or on the shell itself.

Differences of thermostatic mixers by installation method

By the method of installation, mixers with a thermostat can be:

As it is already clear, such mixers are installed directly on the wall, and all engineering communications (water supply) are hidden into the wall.

All plumbing reinforcement in such mixers is in a hidden mounting part, which is mounted in the wall, and only controls remain outside: levers, valves, switches, etc.P.

A classic way to install on a sink, board of a bathroom or a bowl bidet. Such mixers involve water supply from below.

Principle of operation

The use of such a mixer in the bathroom ensures the maintenance of temperature at the level given by the owner. All that needs to be done is to configure the parameters of temperature and pressure. The rest will make the mechanism itself. Regardless of the pressure of cold and hot water, turning on such a tap mixer, a stream of water of the desired temperature will run.

The work of the mixer with the thermostat is based on the same principle. Water supply is adjusted by the thermo element. If hot water disappears, then it automatically overlaps and cold. Therefore, taking a shower, you will not encounter discomfort.

The body of the device has a cylindrical shape and is equipped with two regulators. To set up water pressure and temperature selection as part of the design of the mixer, there is a thermostatic cartridge, which has sensitivity to the temperature difference.

The cartridge consists of a special material, which allows it to push a special piston when expanding it. Thus, the temperature and or ceiling hot water are adjusted if the cold disappears from the water supply network. There is another detail inside the case. ceramic cartridge. Thanks to him, the owner can adjust the water temperature in a wide range. However, there is a limiter that will not allow you to set the temperature above 80 degrees.

Based on such a criterion as the type of water supply adjustment, all mixers with a thermostat are divided into:

The mechanical mixer has a valve and handles in its design. In most models, they are located along the edges of the cylindrical case. The necessary water temperature is exposed to one valve. Another is used to adjust the pressure. Simplicity and reliability. The main advantages of mechanical models.

Electronic mixers have a variety of design. In addition, they have a display with sensory or button control.

Pros and cons

Faced mixers are characterized by certain advantages:

  • Safety. Using them in the bathroom, you will never encounter discomfort from ice water. In addition, such equipment is safe when using children. Many models are equipped with special locks that exclude an independent change in temperature by the child;
  • Economy. Using such equipment in your bathroom, you do not have to spend time adjusting the water temperature. And this is extremely important today, when water meters are installed in each apartment;
  • Dependence on other family members or neighbors is excluded. If you take water procedures in the bathroom, and someone uses water in the kitchen or in the toilet, then you will not experience discomfort in the form of a changed stream or pressure temperature. The thermostat mixer provides stability and automatic maintenance of a given temperature.

How To Install a Thermostatic Shower Mixer Easily

But such almost advanced devices still have a minus. for such mixers are quite high, and for a certain part of people, such equipment in the bathroom is simply not affordable.

Selection criteria

When choosing a tumor, it is better to give preference to products of well.known brands. This guarantees high quality and reliability. Make sure you purchase an original model, not a fake. Remember that a high.quality tumor cannot have a very low price. When buying a foreign brand’s products, specify whether it is adapted to domestic pipe wiring schemes. You should also find out what the minimum pressure in the apartment should be to install a tumor. As a rule, this is 0.5 bar.

The next criterion is the appointment of a mixer with a thermostat. It is important to consider in which room the device will be used. For example, kitchen models can be equipped with rotary spouts (more comfortable washing of dishes), nozzles with aerators. In addition, they have a higher spout, for example, in the sink you can wash a stack of dishes.

The mixers with a thermostat on the sink are usually more compact, have a short spout. Soul models immediately supplied the desired temperature in the mental watering can. There are also mixers simultaneously for the washbasin and shower, water switching is carried out using a special lever.

The next criterion is material. Preference should be given to brass, copper or bronze models. Such devices will serve for a long time. If the appearance is priority, you should pay attention to ceramic mixers. But it is better not to buy models of plastic or aluminum-cream alloy, their operation will not be long. Another parameter that is paid attention to when buying is a valve type. It is ceramic, leather or rubber. Ceramic valves are installed on more expensive mixers, it is more reliable, since the settled impurities and garbage do not disable this element.

The operation of the mixer with a ceramic valve does not imply the use of gross force when closing the valve. this is fraught with a breakdown of the crane head. Leather and rubber valves serve as a shorter period, however, their replacement does not cause great difficulties (the process is similar to the process of replacing the gasket on a conventional mixer).

However, due to the softness of the material, various contaminants and impurities can fall on the valve saddle, causing its damage. This is fraught with a flood, so at the slightest malfunctions it is worth calling a specialist.

The type of adjusting element is also important. 2 options are possible here. wax and made from a biometric plate. The first is considered outdated, because it has a response time for more than 2 minutes. Famous manufacturers prefer to equip their tumors with a safety valve. This is a very necessary function to avoid random switching of the water temperature in the process of using the mixer. Usually this valve has the appearance of a red button. To change the water temperature, this button is first pressed, and then the necessary temperature parameters are built.

Installation of a mixer with a thermostat

In general, the installation of a thermostatic mixer is not too different from the installation of a conventional model. It needs to be connected in the same way to pipes with cold and hot water, seal all connections, check the operation of the device.

Of course, the procedure for installing the device is slightly different depending on the installation site:

In addition, in the installation of each individual model of the mixer, its own nuances can exist. Therefore, before installation, you should study the manufacturer’s instructions in detail.

In general, the procedure for installing a mixer with a thermostat may look as follows:

  • Completely block the supply of cold and hot water in the house.
  • If necessary, clean and grease shut.off cranes to reliably block the flow of water.
  • Dismantle the old mixer.
  • Unscrew the fasteners of the mixer with a thermostat.
  • Check the integrity of metal disks and threads of a new device.
  • Unscrew the discocentric wheels (counterclockwise movements).
  • Clean disks and discharge from accumulated contaminants.
  • Install old cleaned wheels or replace them with new.
  • Win a layer of the seal to the mixer thread: Fum-tone, pac from.P.
  • Install gaskets.
  • Pushing to the stop.
  • Install decorative pads.
  • Flow the mixer.
  • Install surge, watering can and other hinged elements.
  • Carefully seal all joints.
  • Connect water and check the operation of the device, and also make sure that there are no leaks.
  • Set the temperature of the water coming from the mixer.

The installation procedure for the HansGrohe mixer wall model is clearly presented in the next video material:

For installation of a built.in mixer with a bathroom the bathroom, first a special cavity is made in the wall, as well as the strobes to bring hot and cold water to the mixer, if necessary.

But when it is planned to create a false wall at the installation site, for example, from drywall, it is not necessary to hammer the main wall, the device will be hidden behind the false wall panel.

To seal the threaded joints of the mixer with the thermostat, the pacli, linen thread, fum tone or other suitable sealant are used, as well as when installing the usual mixer

Trying to FIX a Thermostatic Mixer SHOWER that doesn’t get HOT!

A very important point when connecting a thermostatic mixer is the correct connection of the device with the pipes of cold and hot water.

The inputs for the corresponding taps on the mixer are marked. Most models are made for the European standard, so cold water to the mixer should be brought on the right, and hot on the left.

In the post.Soviet space, the water supply is made exactly the opposite: cold water is supplied to the left side of the mixer. When installing the mixer with a thermostat on the water-style water supply, confusion may occur due to these features.

Incorrect connection can cause a breakdown breakdown.

To properly connect the mixer with a thermostat in the bathroom to cold and hot water supply, you can use special flexible hoses

A look inside a failed thermostatic bath shower mixer tap

It is not always possible to simply deploy the mixer, since its excess will be directed upward. To install the wall model, you will have to significantly remake the wiring of the water supply.

For other types of mixers, it will be enough to use a couple of flexible hoses to make a connection correctly.

To configure the electronic model of the mixer, a control panel is used, with which the pressure level of water entering the excess, as well as its temperature, is set.

In mechanical models, setting is performed differently. By default, the manufacturer usually leaves the device in a neutral position, which allows you to get a water flow with a temperature of 38 degrees. Even if such settings are suitable and do not need a change, they must be fixed.

To do this, a protective cover is removed from the mixer, under which the adjusting valve is hidden, and rotate it. It is recommended to use the usual thermometer to measure the temperature of the water.

To configure the mechanical model of the mixer with a thermostat, a special lever hidden under a protective cap, and a household thermometer is used

Centralized water supply in most cases ruthlessly to modern plumbing, including thermostatic mixers.

In addition to the already mentioned problem with low water quality, the danger is a water driver, as well as sudden pressure drops in the water system.

To prevent the problem, it is worth installing a check valve and/or a gearbox, which should be adjusted at the entrance to the apartment tap system in accordance with the characteristics of the mixer.

Varieties of mixers with thermostats

The first division is into mechanical and electronic thermostats. The former are distinguished by their simplicity and effectiveness, they do not require any special knowledge and tools for their installation. We connect the mixer to the pipes with hot and cold water, check for tightness. Next, turn on the water supply, adjust the pressure and set the desired temperature regime. Typically, such faucets are equipped with regulators with scenes defined in degrees.

Of the minuses, it is worth noting not the most accurate monitoring of the temperature by a mechanical thermostat, which affects the efficiency of consumption of communal resources.

Electronic thermosmers are more effective, electronics are responsible for adjusting temperature. It analyzes the pressure and temperature indicators, mixing one or another amount of cold water to hot. Advantages of electronics:

  • accurate and fast work.
  • Increased efficiency when consuming hot water.
  • There are additional opportunities. water analysis, sensory control and much more.

The main minus is dependence on the supply of electricity.

There is one more minus. mixers with electronic thermostats are highly cost compared to mechanical analogues.

Fluckers with a bathroom thermostats with a shower are divided into two more categories. built.in and open. The simplest of them are open, reminiscent of traditional faucets without thermostats. As already mentioned, they are mounted on the pipe protruding from the wall. You can also buy mixers with thermostats built into the wall in stores. Only adjustment handles are outside. everything else is hidden from the user’s eyes in the thickness of the plaster and tile.

Install the mixer: external and hidden installation

By the type of installation, thermostatic mixers are no different from ordinary models: they can be both external and hidden installation. In the second case, the executive mechanism (mixing node), enclosed in a special mounting box, is built into the wall. A similar design is in harmony with any bathroom design. Indeed, the outside the functional part remains outside. a decorative panel with elements of temperature adjustment and water consumption and switching the positions of water supply to the bath or shower, as well as pouring. The installation of the mixer of hidden wall installation can be carried out only at the repair stage, and to the stage of the bathroom cladding with tiles. To simplify the installation of a built.in mixer and facilitate the user’s choice of model, some reinforcement manufacturers (Grohe, Hansa, Hansgrohe, Ideal Standard, Kludi, Oras, etc.) developed special universal systems (blocks) of hidden installation. They comply with a single standard of connecting sizes and fasteners and are compatible with any models (including thermostats) of a particular manufacturer.

As for the external installation mixer, the entire body is attached to the wall, equipped with a water release, to which a shower hose is connected. Outloped body design: oval or rectangular.

The average cost of mechanical thermostats of external installation is 5500–7000, hidden. up to 30 thousand.

Materials and colors

The thermostat mixer can be made of a variety of materials. However, in practice, metal alloys, ceramics and plastic of special samples are used in the mass segment. Only in the elite price range can you find wooden or mixers made of stone. They usually equip a separate exclusive bath. But more often they use brass and bronze.

These alloys are very racks to the harmful effects of water. Mineral salts and crystals are almost not gathering for them. If you compare the two main options, then brass will definitely be preferable. Alloy steel is not used so often. In particularly hard water, the faucets quickly clog from it.

As for Silumin, that is, Silicon-aluminum alloy, it is not durable enough. And there will be a lot of dirt inside. Plastic is used only for single details. It is valued for low thermal conductivity, comparative lightness and chemical resistance. In this regard, ceramics are close to plastic. it is more expensive, but more attractive.

In black bathrooms, the most practical solution is a white mixer. But his black color is not welcomed. it can act oppressively. Only experienced designers can sometimes observe a reasonable measure. The chrome surface helps to increase the attractiveness of the mixer. If the room is relatively small, you can recommend orange or even bright red color.

The room decorated in the style of country will look more pleasant when using the mixer imitating bronze. You can imitate ordinary copper. But such a solution will not fit into the bathroom, where plumbing in the spirit of high-tech or even just modern is used. In a large bathroom without a certain style, you can choose plumbing elements of green and yellow. But in any case, you need to think whether it will be pleasant to see them in a few months, when a feeling of freshness passes.

Manufacturers

Grohe concern’s products invariably fall into all lists of consumer preferences. It looks no less good than technical. Grohe engineers carefully run into each innovation and test in the most stringent modes. Much attention is paid to maximum safety and saving resources.

Hansgrohe brand products deserve attention. Since the founding of the company, it has been trying to achieve the optimal balance of appearance and functionality. Hansgrohe mixers and shower design is almost limitless in its diversity. The range includes goods of a very different price range. There are options:

  • water flow control when you press the only button;
  • thermostat cooling (the risk of burn is reduced);
  • aeration of water;
  • maximum savings;
  • fast removal of lime plaque.

Fans of Italian products should pay attention to the brand Bandini. The developers of the company try to realize the maximum personality. not forgetting about advanced developments. The characteristic features of Bandini plumbing differ from the collection to the collection.

There are collections with both classic and modern execution. But in any case, for the products of this brand you will have to give solid money.

Tips from pros

Before buying one or another model of the mixer, you should clearly know what is the temperature of the water that is supplied to your house. For some time, it will not be superfluous to measure it, after which it will be possible to choose a device that will work perfectly with such temperature parameters.

Before buying, decide what type of model you need. built.in or open. Also, it will not be superfluous to determine what material the crane should be made of. You can simply read about the advantages and disadvantages of each type above. In addition, the installation of special filters should not be neglected. Otherwise, the breakdown of such a mixer will be a matter of time. Do not also neglect the adjustment of the crane. If it is designed for one temperature, and the water from the tap is hot, then sooner or later such a mixer will fail.

Another important advice. choose thermostatic cranes based on reviews. This will allow you to choose a really reliable model that will last more than one year.

The selection of thermostatic mixers for the home is a difficult process, which requires a conscious approach and understanding of all its actions. Even before the acquisition of a particular model, it is necessary to take into account all the main points and imagine how your kitchen or bathroom will look and what kind of mixer type will be installed there. But thanks to the tips stated above, you can definitely choose a high.quality and interesting model that will serve for a long time and provide comfortable use of water in your home.

About how easy it is to install a Grohe thermostatic mixer for a bath, watch in the next video.

Standard components for all mixers

Knowing the names and functions of components will help when repairing and orienting in the acquisition of new necessary spare parts for replacement:

  • Aerator. part located at the end of the excess of all types of structures. Serves to uniform distribution of the jet.
  • Pour. the so.called nose of the mixer supplying water. Depending on the length, long, medium and short.
  • Water opening and closing devices. In two.wagon structures, these are cranes, in one.legged. lever, for thermostatic. on/off panels.
  • Action mechanisms, for example, cartridges or crane bouxes, depending on the model.
  • Showers: hose, watering can, switch of bathtub-dush.
  • Other spare parts: fittings, eccentric, linings.

Types of thermostatic mixers

Today, the assortment of devices that supply water comfortable for bathing is regularly increasing. Manufacturers are ready to offer faucets with a bathroom, shower, shells, as well as a bidet. In this case, the models differ in the method of fastening. For example, there are devices for visible and hidden installation.

In general, devices are divided into two groups: mechanical and electronic. This factor must be taken into account when choosing. After all, representatives of each of these two groups have both advantages and disadvantages.

Mechanical adjustment devices

The simplest and, accordingly, cheap is the mechanical model. Such a mixer is equipped with valves, levers and handles that allow you to regulate the force of water flow and its temperature.

Devices with mechanical adjustment are much more reliable and durable. At the same time, they work faster, since temperature switching occurs in manual mode. As for the price, the cost starts from 60.

The disadvantage of mechanical thermostatic mixers is the peculiarity of manual setting parameters. But if the most simple and inexpensive plumbing equipment is required, then this minus does not play absolutely no role.

The design of mechanical equipment, as a rule, is minimalistic and does not contain any unnecessary details, which allows you to easily control it

Electronic thermostatic mixers

If the house is equipped in the Art Nouveau style, it is better to give preference to electronic equipment. In most cases, such mixers have a laconic and elegant appearance, which harmoniously fits into any interior.

In addition, electronic models are equipped with a screen based on liquid crystals, where the current water temperature is shown, as well as the pressure force.

Such mixers are controlled using mechanical or sensory buttons. The market also presents contactless devices operating thanks to infrared sensors. They are often controlled using a special remote control.

If we talk about the advantages of electronic thermostatic mixers, then the pluses include:

  • Comfortableness. they allow you to indicate the temperature of water with accuracy up to 1 ° C;
  • attractiveness-electronic models look in a modern way;
  • multifunctionality. they can display many additional parameters on the display.

But it should be noted that electronic equipment will cost several times more than a mechanical. over, due to the complexity of the design, it is quite difficult to install such mixers correctly. And in the case of a breakdown, you will have to call a qualified specialist, which will also hit the family budget.

Electronic thermostatic mixer needs a power source. For this, batteries or network adapter can be used
