How do thermostatic radiator valves work?

It’s often mentioned that using a thermostatic radiator valves (TRV) appropriately can save you money, but how do they do this? In this blog, we’ll provide you with a short guide on how these controlling devices work, and how to sensibly use them.

Many households will have a thermostat for their central heating system, and while this does regulate the temperature by controlling boiler activity, it does it based solely on the conditions in the room it’s located in. By adding TRVs, you can create different zones with varying warmth.

TRVs essentially react to the temperature in a room to adjust the flow of hot water to a radiator. They can typically be set to a value of between one and five, to indicate your desired level of warmth. When the room temperature drops too low, a capsule in the TRV contracts and opens the valve further to allow more hot water into the radiator. When it gets too hot, it expands to push the valve in and lower the flow.

What this essentially means is that you can create the optimal conditions for each room. For example, you will probably want the living room, a place of relaxation, to be one of the warmer rooms in the house, as this is where people are more likely to spend extended periods of time. However, less frequently used rooms are unlikely to require the same level of warmth. Therefore, you can use your TRV to set appropriate settings for each radiator in the house, which may be different to the temperature on your thermostat. This can help you save money on your heating bills if you decide to use TRVs to make some rooms warmer than others.
