Mixer with thermostat: the best solution for connoisseurs of comfort and safety

Modern society is increasingly striving for inventions that allow the rational use of water, electricity and gas. Therefore, all kinds of sensors, regulators and other devices are rapidly breaking into everyday life. A mixer with a thermostat is very popular today, which is a multifunctional device that serves to maintain a given water temperature, while saving electricity for heating it.

Thermostatic mixer: what is it

A mixer with a thermostat is a device that not only mixes hot and cold water, but also maintains the temperature of the liquid in a given mode. This device also provides adjustment of the water jet pressure, which is especially important for apartments in multi-storey buildings.

Considering the structure of the mixer, we can say that the structure includes a body, a temperature limiter, a thermostat, a jet pressure regulator, and a temperature scale. The cylindrical body has two water supply points and a spout for its outflow. The temperature limiter is represented by a switch located on the right side of the device. It locks the device when the temperature rises above the set value, keeping it at the desired level.

Thermostat - what is it? It is produced in the form of a cartridge or cartridge that changes the ratio of hot and cold water, providing a water jet of a given temperature. This process is carried out within a few seconds thanks to the sensitive moving elements. They are made of materials that are highly sensitive to any temperature change. It can be paraffin wax, wax or bimetallic rings.

High temperatures cause the material to expand, while low temperatures cause it to shrink. As a result, the cylinder moves in the cartridge, opening or narrowing the space for the movement of cold water. This is how a thermostatic mixer works.

Important! To exclude the squeezing of the damper, which is responsible for the access of water of different temperatures, the design is equipped with a check valve.

The thermostat switches in 4 degree increments. Each thermostat is equipped with a maximum temperature limiter with a value not exceeding 38 ° C.

In the event of a sharp decrease in the supply of hot or cold water to the system, only the pressure of the jet decreases, and the temperature remains the same. If water does not flow at all, or its pressure is not enough to maintain the set temperature, the thermostat shuts off the water flow.

The pressure regulator is represented by a crane-axle box, which is located on the left side and provides switching on and off the water flow, bringing it to the desired mode at the outlet.

Advantages and disadvantages of a thermostatic bath mixer

Having considered the principle of operation of a mixer with a thermostat, we can say with confidence that the device is an indispensable element of bathroom fixtures. It is characterized by ease of use, which is ensured by the ability to maintain the water temperature in a given mode. There is no need to periodically adjust the water temperature, depending on the operation of the centralized system, manually.

The device will independently configure the system according to the specified parameters, which will allow you to simply enjoy the water procedure. This is especially valuable for families with small children and elderly people. This device is also relevant in homes where seriously ill people and people with disabilities live.

The next time the water flow is turned on, the thermostat will automatically adjust the preset operating mode. It will be maintained throughout the entire period of water use, which eliminates the possibility of scalding or uncomfortable conditions in the event of a sudden change in the pressure and temperature of the centralized water supply.

Important! The thermostatic faucet is designed with GROHE Cool Touch technology to ensure that the body never gets too hot.

Installing a thermostatically controlled mixer is a cost-effective option and saves water and energy. It is not necessary to drain the water until it reaches the required temperature. This will have a positive impact on the payback period of the device, the price of which is quite high compared to traditional mixers.

The installation of such devices is similar to the process of installing traditional devices and is a simple, labor-intensive procedure that does not require special skills.

It is worth knowing that the operation of the mixer depends on the water pressure in both pipelines. In the absence of pressure in one of them, the valve will not allow water to flow from the other pipe. However, there are models equipped with a special switch that allows you to use water.

The disadvantages of the device include the high price of a thermostatic mixer, difficulties in repairing it, since specialized centers that can cope with breakdowns do not exist everywhere.

Varieties of shower mixers with a thermostat by control type

Thermostatic mixers, depending on the control method, can be mechanical, electronic or sensor. The first version of the three-way mixing valve is a simple design that is affordable.

The water temperature is regulated using valves or levers. They provide movement of the valve inside the body, depending on changes in temperature. It moves towards the pipe in which more pressure is created, reducing it. The water temperature remains the same. Such a faucet with a thermostat has two regulators - temperature and pressure. The first is on the right and the second is on the left.

The thermostatic electronic faucet is more complex and expensive. To ensure its functionality, you must connect the device to the outlet. There are stand-alone models that run on batteries. The valve with a thermostat is controlled using buttons, a touch panel or a remote control. Electronic sensors control all water indicators, the numerical values ​​of which are displayed on the screen. This type of mixer is notable for its comfort, versatility and attractiveness.

Among the newfangled technologies, one can single out a contactless device that, thanks to a sensitive infrared sensor, reacts to a light touch. It is enough to bring a hand to the body - and water of the specified temperature will flow from the tap.

Despite the ease of use, the sensor mixer has significant drawbacks. In order to fill the container with water, you need to keep your hand in the sensor's area of ​​effect all this time. It is possible to quickly change the water temperature using thermostatic kitchen faucets, which are equipped with a single-lever mechanical regulator. Expensive options are not practical for changing water temperatures regularly. In addition, there is no way to control the period of water supply, which is a significant drawback in terms of resource saving.

Helpful advice! It is advisable to install sensor faucets with a thermostat in the kitchen: this allows you to turn on the water without smearing the tap with dirty hands, which creates convenience in the cooking process.

Varieties of thermostats depending on the purpose and installation method

Depending on the purpose, thermostatic mixers are central or used for operation at one point. The first version of the device is a single center design that can be used for multiple water supply points. Such a mixer is installed in rooms with high traffic. These can be sports complexes, industrial premises. This option is also suitable for a residential building where several points are provided with water supply: shower, bidet, washbasin.

Important! Buying and maintaining one central thermostatic mixer is more cost effective than installing several elements.

Three-way valve mixers designed for single point use are classified based on functional load. All of them are subdivided into devices of open or hidden installation. The devices are used for kitchens, washbasins, bathtubs and shower stalls. Kitchen faucet with thermostat, it can be installed on a wall, countertop or sink in an open way, as well as a closed installation. In this case, the spout and valves of the crane remain in the field of view. All other elements are hidden in the wall. For this, built-in mixers with a thermostat are purchased.

However, installing thermostatic mixers in the kitchen is not always justified. This is due to the fact that you constantly need to change the temperature depending on the type of activity. You will need cold water for cooking, wash the food warm and the dishes hot.Constant temperature fluctuations will negatively affect the efficiency of the device. Moreover, in this case, its value is minimized.

Types of faucets with thermostatic bath and shower

The thermo mixer for the washbasin is able to fully cope with the task of maintaining the water temperature in a given mode. The upright model with a drainage spout can be installed on a sink or wall. The thermostatic bath and shower mixer includes a spout and a shower head. Such a device is mainly made of chrome-plated brass.

Helpful advice! For the shower, you can install a universal thermo mixer with a long spout or a cascade model that provides a wide strip of water flow.

The thermostatic mixer for the shower stall is equipped with a watering can only. The option is convenient to use and is installed in a hidden way. The pressure and temperature regulators remain in sight, and the rest of the mechanism is hidden in the wall.

For the shower, you can install a push version of the thermo mixer. To bring the device into working condition, you must press the large button. The water will run out for a while, after which it will stop.

Depending on the installation method, thermostatic mixers are horizontal, vertical, floor-standing, wall-mounted, concealed and options that are attached to the side of the plumbing device. Built-in thermostatic faucets are similar in appearance to shower products. They differ in the presence of a special reservoir for wall mounting.

Which is better to choose a mixer with a thermostat: materials for manufacturing

There are a few things to keep in mind when choosing a quality and durable thermostatic bath mixer. First of all, you should pay attention to the material of the case. Ceramic, plastic or metal can be used here. Ceramic products have an attractive appearance, but they are characterized by poor wear resistance and susceptibility to mechanical stress. This is due to the fragility of the material, which is noted in the reviews. Faucets with a ceramic thermostat are relatively expensive.

Metal faucets can be made of bronze, brass or copper. Such products are quite reliable, strong and durable. The main disadvantages of metal thermo mixers include their high cost. There are cheaper models made of an alloy of metals - silumin. However, they are fragile, as evidenced by numerous reviews. The thermostatic bath faucet made of plastic is the most affordable option, but it has the shortest service life.

You should also pay attention to the material of which the valve of the cartridge for the thermostatic mixer is made. It can be leather, rubber or ceramic. The first two options are characterized by low cost, but they are less wear-resistant and durable. Such gaskets will quickly become unusable if solid particles enter with water.

The ceramic valve is more reliable. He is able to push out solid particles that have entered his body. Such an element has a graphite coating, which prolongs its service life. However, due to the fragility of the material, the valve should be screwed in all the way down with great care so as not to damage the integrity of the head.

Useful tips for choosing a quality mixer with heated water

Choosing a thermostatic mixer for a bath with a shower, you need to inquire about the connection diagram of the distribution pipes for the water supply. European manufacturers offer plumbing fixtures created according to their own standards, where hot water is supplied on the left and cold water on the right. Russian designs assume the reverse order of connection. There will be no problems installing them. If a device made according to European standards is chosen, you will have to redo the order of the supply pipes.

Important! If the pipeline is incorrectly connected, the device will immediately break.

Many popular models are equipped with a safety valve to prevent accidental changes in water temperature. Such an element looks like a button, which is colored red. To change the temperature of the water, just squeeze it out. This option is especially valuable for families with small children.

Before installation thermostatic mixer for hygienic shower it is recommended to install a filter on each pipeline to prevent the ingress of small particles into the device supplying water. Clogging will negatively affect its performance and reduce the service life. It should be remembered that it is advisable to install a mixer with a thermostat on pipelines where a pressure of at least 0.5 bar is ensured.
