Switching to a Combi Boiler: If the issue stems from an old system that’s no longer efficient, switching to a modern combi boiler may resolve the problem entirely.
Consider Installing Zone Heating: If certain rooms are consistently colder than others, installing zone heating or thermostatic radiator valves can help regulate temperature more effectively.
Frequent Questions:
Why does my boiler seem full, but the radiators are cold?
This often happens if the system is airlocked, has incorrect pressure settings, or if there’s a blockage in the pipes. Bleeding the radiators and checking the pressure can help.
Can I fix this issue myself?
Some issues like bleeding radiators or adjusting the pressure can be done by the homeowner. However, for more complex problems, such as pump failure or internal blockages, you may need a professional plumber or heating engineer.
What could the plumber have gotten wrong five years ago?
It’s possible that the plumber incorrectly diagnosed the system’s issue or overlooked maintenance tasks that have now worsened over time, such as improper pressure settings, blocked pipes, or malfunctioning components.
Is it normal for radiators to be only slightly warm?
No, radiators should be hot to the touch. If they are lukewarm, there is a problem in the system that needs to be addressed, such as airlocks, blockages, or a malfunctioning pump.
