These devices are used to automatically mix cold water into hot water, which allows maintaining the set outlet temperature. They are great for boiler heating systems and with some reservations for other types, and anyone who can hold an open-end wrench can handle the installation and configuration

The thermostat is supplied in a soft bag, the hot and cold inlets, as well as the mixed water outlet are signed, there is a grid at the inlet
A part of the cartridge is visible from below, it looks like copper in color. In the upper part there is a temperature regulator from 20°C to 50°C
You can freely turn the knob only up to 38°C, in order to raise the temperature higher, you must press the safety button. This solution will save an inexperienced user from injury.
The principle of operation is both simple and ingenious. Inside there is such a cartridge with two circuits
Until the hot water reaches the set temperature, the cold circuit is closed. When overheated, the thermostatic element begins to move, slightly opening the flow of cold water and covering the flow of hot until the outlet temperature drops to the set temperature.
If you already have a faucet installed, there are two installation methods. The easiest way is to directly connect the thermostat to hot and cold water, connect the outlet to a mixer and use only warm water of a given temperature, an example in the picture on the left. I did the installation in the kitchen, where sometimes cold water is needed, so I had to buy another tee to connect to the cold water pipe for mixing and a couple of corners to step back from the wall, because. tubes were close. The result is in the photo on the right, the temperature was set around 42 ° C
The temperature in the boiler is 60°C, in the bathroom the flow reaches this value quite quickly. But in the kitchen, when you open a hot water tap, it jumps up to a maximum of 42°C and adjusts to 38°C as the cartridge warms up. The scale is not accurate, but I still corrected the desired value without looking, keeping my other hand in the flow
Results
I’ve been using it for the third month and have already forgotten what it’s like to catch a comfortable temperature with two taps of a mixer and burn my hands in the morning, when it manages to rise from room temperature to 60 ° C in a second, so this is definitely a good thing, especially considering the price of just over $10
Installation takes 10 minutes, all you need is a few wrenches of the right size and a third hose. If you plan to leave cold water, then another tee for it.
This solution may not be suitable for owners of gas water heaters without flame modulation, because during adjustment, the thermostat will cover the flow of hot water, which reduces the flow and increases the temperature in the circuit, and this can lead to overheating.
If there is a pressure difference in the lines, it is necessary to install check valves to prevent hot water from flowing into cold water when the tap is closed.
Also, many recommend disassembling the case before use and treating the cartridge well with heat-resistant grease, this will save the formation of salts on its surface, otherwise it will start to wedge over time due to hard water.
At the time of purchase in this store, the cost was the most humane, delivered in a week check the price
For the bathroom, I looked at this option, which is simply put in place of the old faucet to check the price
