thermostatic radiator valve simulator

This DIY explains how a thermostatic radiator valve operator works.

This type of valve, found on most radiators today, limits automatically the amount of hot water passing through the radiator to maintain a room at the right temperature.

Inside, a valve system expands according to the ambient temperature and opens or closes the hot water supply to the radiator.

The thermostatic valve is therefore more than just a faucet that can be opened or closed at will to regulate the heating!

The basic settings are as follows:

    Bathroom: 4 (22°C)

    Living room or kitchen: between 3 and 4 (20-22°C)

    Bedroom: between 2 and 3 (18-20°C)

    Hall: 2 (17°C)

    Lightly used room, laundry room: between 1 and 2 (15-17°C)

These settings can be modified slightly if you find that a room is systematically too hot or too cold.

Setting the right heating temperature is very important to avoid wasting energy. In fact, each additional degree means a 6 to 10% increase in consumption!
