Thermostatic Radiator Valves


Thermostatic radiator valves (TRVs) are essential in heating systems, providing individual control of room temperatures. These valves automatically adjust the temperature based on user settings for energy efficiency and comfort.

Thermostatic or smart radiator valves can help improve your home’s energy efficiency by controlling the temperature of a room. Pick up a multi-pack to save on installing thermostatic radiator valves throughout your property.

Smart Radiator Valves


Smart radiator valves offer advanced control, letting users regulate room temperatures with smartphone apps or voice commands. They enhance energy efficiency and convenience with personalised schedules and room-by-room heating control. Explore smart radiator valves at Toolstation for a convenient and intelligent solution.

Radiator Valve Extensions


Consider adding valve extensions if your radiator valves are in a hard-to-reach space. Our range includes flexible radiator valve extensions that can be cut to the right length.
