Thermostatic mixer: what is it?

The mixer is one of the most common plumbing devices, because you can find it in every home. But most models have a significant drawback - dependence on water pressure in the system. This parameter is not constant, and therefore either hot or cold flows from the tap.

You can improve the device, making it a real assistant, using a thermostatic device. A product that automatically regulates the temperature of the supplied water cannot be called a new product on the plumbing market. However, in Russia, such devices are just beginning to gain popularity, so they are familiar to a narrow circle of consumers.

Mixer with thermostat: what it is and how it works

Residents of European countries are famous for their reasonable approach to the use of resources. It was they who came up with a variety of temperature sensors and other similar devices that save water, heat, and electricity. One such device is a mixer with a built-in thermostat.

The thermostatic mixer is designed to provide a stable outlet water temperature, independent of its pressure in the water supply. It not only copes with the task assigned to it, but is also easy to operate and has an ergonomic appearance.These parameters are important for modern consumers.

Simplicity of design and clear operating principle ensure long service life and inexpensive maintenance.

How does a modern plumbing product work? Simple enough. The secret of the device lies in a special valve:

1. A small part reacts sensitively to even a slight change in pressure in one of the water pipes.
2. If there is a deviation, the valve regulates the pressure in one pipe while simultaneously changing it in the other.

All operation of the device takes place according to predefined settings. For example, if the pressure in a pipe with hot water decreases sharply, the valve will limit the flow of cold water into the system.

The product is easy to use, even children can handle it. Externally, the device is practically no different from the standard version - the same “lambs” or handles, drain spout and body.

The difference between a regular faucet and a device with a thermostat lies in the design of the levers. One of them is necessary to regulate the temperature of the supplied water, the second is responsible for its pressure. It is enough to set the required parameters once, and in the future you will only need to open the tap.

Reference. To protect the younger generation, which is characterized by increased curiosity, the mixer with a thermostat is equipped with a special fuse.

Advantages of a thermostatic mixer

The device has a number of undeniable advantages. The main thing is to regulate the temperature of the supplied water. But there are a number of other advantages that you need to know before buying a device:

1. Ease of use. The product is equipped with a temperature regulator. Therefore, there is no need to expose it every time.
2. Safety. Even if there is no cold water in the system, the fuse will protect you from possible burns.
3. Economical. The device allows for more efficient use of resources. Since the temperature does not have to be adjusted each time it is used, water will not be wasted into the sewer system.
4. Easy to install. Installing the thermostat is no different from installing a standard product.

Disadvantages include dependence on the availability of water. If there is no cold or hot water, the valve and fuse will block the operation of the device. However, you can find models equipped with a special switch on sale. If necessary, the user can manually open the valve and continue using the mixer.

When should you install it?

Experts recommend installing a thermostat in the following cases:

1. With frequent temperature changes in the system. They can occur when neighbors on the riser turn on the water or when the water supply is used simultaneously in several rooms. In addition, in some houses temperature changes occur regularly for reasons beyond the control of the residents.
2. When using storage type water heaters. There are two options: electric and gas. Depending on the model used, the water can be heated up to 85 degrees. If you suddenly turn off the cold water while taking a shower or washing dishes with a standard faucet, you risk serious burns.
3. When using flow-type geysers. When using this type of heater, it is quite difficult to adjust the required temperature. This is especially difficult to do in the case of regular pressure surges in the pipes.A mixer equipped with a thermostat will eliminate these problems and make the use of geysers comfortable. In addition, some models of geysers sometimes malfunction, causing the maximum gas supply to be turned on. In this case, a thermal mixer is simply necessary - it will protect you from burns.
4. If there are children in the family. Kids are extremely inquisitive people. Therefore, situations are common when a child independently turns on hot water and gets burned. To avoid this, install a modern faucet in the bathroom and kitchen.

Types of faucets with thermostat for showers

There are several options: specialized and universal. The first are intended to work with a specific product: bathtub, sink, bidet, shower. The latter are considered universal and compatible with a variety of plumbing fixtures.

The following options are available for showers:

• a water thermostat for a shower that does not have a special spout;
• products that include, in addition to the required elements, a watering can, a water supply switch, a drain - they can be of various shapes, but more often there are models in the form of a tube ending with a switch;
• For shower stalls, models are available without a watering can and drain - all structural elements are connected using small tubes;
• special products for showers with hydromassage, where it is especially important to maintain a constant strong water pressure.

In addition, depending on the functionality, thermal shower mixers are divided into two types:

1. Mechanical. They are equipped with standard controls: thumbwheels, valves or handles. With their help, a comfortable water temperature is set. The advantages of the product are quick response to changes in pressure, long service life.
2. Electronic. Control is carried out using the touch panel. The thermostat display shows temperature and pressure. The products are convenient and easy to use, and also allow for precise adjustments.

Modern plumbing has a lot of advantages, the only significant drawback is the cost. It is this that prevents the widespread dissemination of economical, comfortable plumbing fixtures. But the purchase quickly pays for itself, as it makes water consumption economical, which means it reduces utility bills. In addition, it is indispensable for families with small children, because the thermostat can protect curious kids from burns.
