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.
How to choose the correct radiator valves?
To pick the right valves, consider these key factors:
1
Choose Between Manual vs. Thermostatic Valves
Manual Valves: Simple, cheaper, but require manual adjustment. Best for small rooms or radiators on a central thermostat.
Thermostatic Valves (TRVs): Automatically regulate temperature, saving energy. Ideal for bedrooms, living rooms, and energy-efficient homes.
2
Check Your Pipework Orientation (Angled, or Corner Valves)
The type of valve you need depends on the pipework direction:
a pair of
angled valves required
a pair of
angled valves
or
a pair of
corner valves required
3
Choose the Right Size (15mm is Standard)
Most UK domestic radiators use 15mm valves, but check your pipe size in case you need 8mm or 10mm.
