You can adjust the heat on a radiator by turning the thermostatic valve, usually found on the side.
The most common way to adjust the heat coming from your radiator is by manipulating the thermostatic radiator valve (TRV). Here's a more detailed breakdown:
Identifying the Thermostatic Radiator Valve (TRV)
- Location: Look on the side of the radiator, usually near where the pipes connect.
- Appearance: TRVs usually have a taller, cylindrical cap with numbers printed on them, often ranging from 0 to 5. Some may use other symbols or have a digital display.
Adjusting the Heat
- Increase Heat: Turn the valve dial counterclockwise. This opens the valve, allowing more hot water to flow into the radiator and increasing the heat output.
- Decrease Heat: Turn the valve dial clockwise. This closes the valve, restricting the flow of hot water and reducing the heat output.
- Settings: The numbers on the valve represent different temperature settings. A higher number corresponds to a higher room temperature. Setting the valve to "0" typically shuts off the radiator completely.
Other Radiator Valve Types
While TRVs are common, some radiators may have different types of valves:
- Manual Valves: These are simpler valves that you turn to control the water flow. They don't automatically regulate temperature. To adjust, simply turn the valve to increase or decrease the water flow.
- Lockshield Valves: These are usually found on the opposite end of the radiator from the TRV (or manual valve). They are used to balance the heating system and are typically not adjusted frequently.
Troubleshooting
- Radiator Not Heating: If your radiator isn't heating, make sure the valve is open and that the boiler is working correctly. You may also need to bleed the radiator to release trapped air.
- Stuck Valve: Sometimes TRVs can get stuck. Try gently tapping the valve body to loosen it. If that doesn't work, you may need to consult a professional.
By understanding your radiator's valve and following these simple steps, you can easily adjust the heat and maintain a comfortable temperature in your home.
