To fill a radiator in a house, you generally need to focus on filling the entire heating system rather than just an individual radiator. The following steps outline the process, incorporating key points from the reference material.
Step-by-Step Guide to Filling Your Heating System
Here's how to fill your heating system, including radiators:
-
Locate the Filling Loop:
- Identify the filling loop, usually a flexible pipe with valves connecting the mains water supply to your heating system.
-
Slightly Open the Filling Loop:
- Gradually open one of the valves on the filling loop to allow water to enter the system. This is mentioned in the referenced video at 0:40: "Open the filling loop slightly."
-
Bleed Downstairs Radiators:
- Start bleeding the radiators on the lowest floor of your house. This helps remove trapped air as the system fills with water. The video at 0:40 also states: "And bleed all the downstairs radiators. First."
- Use a radiator key to open the bleed valve.
- Close the bleed valve once water starts to come out.
- Start bleeding the radiators on the lowest floor of your house. This helps remove trapped air as the system fills with water. The video at 0:40 also states: "And bleed all the downstairs radiators. First."
-
Bleed Upstairs Radiators:
- After you've bled the downstairs radiators, move upstairs and repeat the bleeding process for all radiators there. The video mentions at 0:40 "...Once you've done this bleed all the radios upstairs."
- Don't forget towel radiators if you have them (as mentioned in the video at 0:40).
-
Monitor System Pressure:
- Keep an eye on the pressure gauge on your boiler as you fill the system. Ensure the pressure is within the recommended range (usually around 1 to 1.5 bar when cold, but check your boiler’s manual).
-
Close the Filling Loop:
- Once the system is full and pressure is correct, fully close both valves on the filling loop.
-
Check and Re-bleed:
- After the heating system has been running for a while, check the radiators and bleed them again if needed.
Key Considerations
- Safety First: Always consult your boiler's manual and if you're not comfortable, consider calling a professional.
- Slow Filling: Fill the system slowly to prevent airlocks and damage.
- Regular Checks: Regularly checking and bleeding your radiators can keep your system efficient.
By following these steps, you should be able to fill your heating system and radiators effectively.
