What are radiator valves and how to choose the correct one?

Radiator valves control the flow of hot water into a radiator, allowing you to adjust the heat output or turn the radiator off when needed. They play a crucial role in energy efficiency and temperature control.

There are two main types of radiator valves:

  •   Manual Valves - Work like a tap; you turn them to increase or decrease the water flow.
  •   Thermostatic Radiator Valves (TRVs) - Automatically adjust the heat output based on room temperature.

    Choose between manual vs. thermostatic valves

    Manual Valves - Work like a tap; you turn them to increase or decrease the water flow.
    Thermostatic Radiator Valves (TRVs) - Automatically adjust the heat output based on room temperature.

    Check your pipework orientation (angled, or corner valves)

    The type of valve you need depends on the pipework direction:

    Angled
    Valves

    Corner
    Valves

    Choose the right aize (15mm is atandard)

    Most UK domestic radiators use 15mm valves, but check your pipe size in case you need 8mm or 10mm.
