Thermostatic mixer and radiator tap, discover how the thermostat is part of the daily life of this family, in the video below.


At the core of each thermostatic product, there is a small part which is called the thermostatic element.

Inside this element, there is wax based paste. When this paste is heated, it expands and grows larger, and it pushes the metal rod of the element (the piston). This movement is the basis of operation of the applications. It will be used to adjust the inlet of hot and cold water, or hot and cold air.

The thermostatic element is in fact a smart thermometer, which is independent and very precise. It analyses its environment without you asking it to do it, in order to ensure that you have the temperature that you want.

Beware of cheap products!

Thermostatics are great but if you don’t choose a cheap product. Proof, my 30€ mixer lasted only 6 months. I bought one which was a little more expensive and now, everything is fine.

Great for heating

Nothing to do with the old electric convector at my parents home. With my thermostatic radiator heads, I always have the right temperature in my home.

A real difference!

Compared to my mixer in which the temperature doesn’t stop varying, I am happy with my thermostatic tap. The temperature is always the same, it’s really pleasant not to have to regulate the temperature all the time.
