Mixer with thermostat: device and principle of operation + self-assembly example

Man always strives for comfort in its most diverse manifestations. This applies to both global phenomena and small things. It is not enough for him to hold a water supply system in his home and equip it with heating, the turn has reached the maintenance of a given temperature and the pressure of a water stream. For this, the thermostatic mixer was invented, a very popular design around the world. Now he is actively conquering the Russian market.

What is a thermostatic mixer?

Thermal mixer - a programmable device that maintains a given water temperature. Most models can also regulate the pressure of the jet, whose level can also be programmed.

Typically, a mixer with a thermostat is equipped with two controls. With the help of one, the desired temperature is set, with the help of the second, the pressure level. In this case, most often the first is set the heating level, then the water is turned on and the desired pressure is set.

The industry produces two types of devices: electronic and mechanical. The first option is easy to determine by the presence of a liquid crystal screen, which displays data on the actual temperature of the water. Such models are powered by batteries or a network adapter. They can be equipped with push-button or touch controls. There are options that respond to infrared sensor signals, that is, working remotely. Mechanical models have the usual controls, the most diverse design. It can be levers, handles or valves.

The electronic mixer with thermostat is equipped with a display for information output

Models differ in their purpose. A special mixer with a thermostat is available for the bathroom, kitchen, shower, bidet or sink. However, there are universal designs that can be used in various conditions. For example, in the kitchen or in the bathroom. Devices differ in their method of attachment. Depending on your own preferences and the expected operating conditions, you can choose between devices for flush and open installation.

Principle of operation and internal arrangement

The design device is quite simple. Each sink mixer with thermostat, as well as other models, is equipped with a special mixing valve, which is regulated by a special cartridge. Sensitive to the slightest temperature fluctuations, the cartridge is made of bimetallic plates or contains wax. As a result, even with small changes in the level of water heating, it begins to narrow or expand. The temperature settings are transferred to the cartridge using the mounting screw.

To ensure safety, a fuse is installed on the adjustment screw, which prevents the water temperature from rising above the 80 ° mark. The fact of the sudden cessation of cold water will be a signal to block the supply of hot.

When the water supply resumes, the mixing process automatically continues. Thus, the thermostatic shower faucet completely eliminates the risk of burns due to a sudden temperature jump.

Overview of the advantages and disadvantages of equipment

Convenient mixers that allow you to maintain a given temperature, many prefer traditional. They are especially relevant for families with the elderly or small children. In addition, they are successfully installed in rooms where adjustment is difficult due to the difference in pressure in pipes with cold and hot water. Practical mixers have many advantages:

• Profitability. Exact settings of the system allow avoiding excessive consumption of hot water, which is especially important if there are electrical appliances in the house for heating it. The overall water consumption, which usually increases during the adjustment process, is also significantly reduced. In addition, the device is capable of operating in a specially set economical mode.
• Absolute safety. During hygiene procedures, you can be sure that the shower faucet with thermostat will not allow water to overheat above the set temperature and will not allow the icy stream to collapse on the washing person. This is especially true for those who use an autonomous water heating system, for example, storage water heaters. Such devices bring water to a temperature of 80 ° C, which is potentially dangerous. A mixer with temperature control in such cases significantly reduces the possibility of accidental burns.

Comfort. The system is independent of pressure drops or water temperature in the pipes. In any case, excluding the complete cessation of water supply, the mixer will supply water of the desired temperature with a given pressure. The device quickly, within about 2 seconds, reacts to the changes that have occurred and properly adjusts to new conditions. Moreover, the result of his work does not change.

And here is a practical mixer with a thermostat, which is equipped with temperature and pressure regulators

The main disadvantage of the equipment is considered to be its relatively high price. Indeed, their cost is slightly higher than that of conventional mixers, which, however, fully pays off with a high level of comfort and safety design. It should be understood that by installing a kitchen faucet with a thermostat, a system for bath or shower, as a result we get an economical and practical device.

It will allow you to save part of the funds for energy and water consumption, provide complete safety and give pleasure always comfortable water temperature.
