How do thermostatic radiator valves work?
Thermostatic radiator valves usually have some sort of numbered dial, ranging from 1 to 5. Each number corresponds to a specific temperature. Typically, 0 equals ‘off’, 1 equals 10°C, 2 equals 15°C, 3 equals 20°C, 4 equals 25°C and 5 equals 30°C. You choose the number that relates to your desired temperature for that particular room, and let your thermostatic radiator valves do the rest!
When the temperature changes, the valve head expands, moving a pin into the valve body. If the room becomes too hot, the valve closes and prevents hot water entering the radiator. Conversely, if the room becomes too cold, the valve opens and allows more hot water in until the set temperature is reached.
In addition to radiators, TRVs can also be used with towel rails, like our Zante model, shown here in Polished Stainless Steel with chrome corner valves
Thermostatic radiator valves allow you to customise the temperature for each room in your home. For example, you may want your main living area warmer than your spare room or (oven-warmed) kitchen.
