Recommendation points



Thermostatic mixer is a modern plumbing device that allows you to maintain the pressure and temperature of the water at a level that is comfortable for you. Economical and safe faucet with thermostat for the bathroom will save you from unpleasant surprises when the pressure and temperature of the water in the system changes.

Features of thermostatic mixers

The main difference between mixers with a thermostat and classic mixers is the presence of temperature sensors that allow you to maintain the temperature at the same level. The jumps in the pressure of hot and cold water do not affect the jet coming out of the tap or shower. The built-in programmable device also supports the thrust force. The desired temperature can be set with half degree precision. Now an unplanned contrast shower will not hit your head, as well as boiling water, even with a sudden decrease in the flow of cold water in the system, the thermostat will keep your comfort. Considering in detail thermostatic mixers, we note the following advantages:

  1. Saving water consumption. You do not have to waste liters, alternately increasing the flow of hot and cold water, trying to get the right temperature.
  2. Comfort. The temperature is set once, you only select the water pressure.
  3. Safety of use. The thermostat will eliminate the possibility of burns. When the supply of cold or hot water in the system is stopped, the mixer is blocked automatically.

In fairness, it is worth mentioning the disadvantages of thermo mixers:

  1. High price. This is especially true of high-tech electronic models with a liquid crystal screen and touch buttons..
  2. Greater sensitivity to tap water quality.
  3. Repair of a thermo mixer is a complex and expensive procedure, moreover, it is not available in all localities.

Types of thermostats

Having opted for a mixer with a thermostat, it is worth exploring the varieties of this plumbing fixture. There are two main types of thermostats on the market: electronic and mechanical. Let’s dwell on each of them..

Electronic

The sophisticated design of the electronic thermo mixer will ensure maximum ease of use. Many models are equipped with liquid crystal displays, which reflect the current water temperature and even data on the actual head force. Such a mixer can be controlled by mechanical or touch buttons. Electronic models usually run on batteries. Devices equipped with infrared sensors for turning on water are especially comfortable to use, but their cost is quite high.

Mechanical

Mechanical thermostatic mixers are easy to install and operate and do not need to be connected to a power source. The device has two regulators that control the water pressure and its temperature. A thermostat is installed in the mixer body, which is responsible for supplying water to the temperature required by the user and a sensor that regulates the pressure.

Device and nuances

The idea behind a thermostatic mixer is pretty simple. The body of the sanitary ware is equipped with a pressure regulator and a thermostatic valve.

Advice! Choose mixer models with a ceramic valve – they are practical and durable. Rubber or leather flap wears out very quickly.

Most thermostatic valves consist of:

  1. Thermostat with a plastic cylinder.
  2. Metal cylinder.
  3. Cartridge.

The thermostat itself, which controls the flows of cold and hot water, consists of a paraffin (wax or polymer) rod and a copper rod. A handle, lever or valve sets the required temperature, the check valve mixes hot and cold water in the required proportion. As the temperature of the water in the piping rises, the wax rod expands and extends the copper rod, increasing the space between the metal surface of the regulator and the plastic cylinder, thereby increasing the cold water flow. A decrease in the temperature of the water in the system causes the wax rod to shrink and the space for cold water decreases..

Connecting faucets with thermostat

Despite the complexity of the device of some models of thermo mixers, this does not affect the installation – the installation of a mixer with a thermostat takes place according to the traditional scheme.

There are three ways to install a thermostatic mixer:

  1. Wall Mount.
  2. Bathtub housing.
  3. Connecting the mixer to a separate rack or shelf.
