How Do Thermostatic Radiator Valves Lower My Bills?

A TRV reacts to changing room temperatures throughout the day, ensuring the heating in an individual room stays at a more constant, comfortable level. Once set to its desired temperature, a TRV-controlled radiator can be left to its own devices.

In contrast, as the name suggests, a manual radiator valve requires human intervention to adjust the room temperature manually. Unfortunately, this effort can result in rooms being left too hot or too cold.

Manual radiator valves can also be problematic for people with mobility issues. Some people may need help accessing manual controls, typically located near the ground, to manage their comfort levels. Accessibility will be impacted further when radiators are positioned behind furniture or in awkward positions.

By more efficiently managing your rooms' temperature, TRVs have also been proven to reduce your energy bills dramatically.

TRVs can be strategically located and set in various rooms of your home. For example, you may wish to increase the level of heat in your living room but find it more comfortable to sleep in a cooler bedroom. Meanwhile, little-used rooms and hallways can have their heating either turned off or set at a more ambient level.

It has been estimated that TRVs can significantly save energy use and costs by only generating heat where and when needed. While these savings will depend on several factors, including the size of your home, room use, and quality of windows, doors, and insulation, we've seen reports estimating energy savings ranging between 17% and a staggering 40%.

From an environmental point of view, TRVs can also help dramatically reduce your home’s carbon footprint.

By replacing manual radiator valves with TRVs, a three-bedroom, semi-detached house in the UK could save at least 280 kilograms (620 lb) of CO2 per year.
