Why are my radiators cold when the boiler is on?

Cold at the top usually means trapped air; cold at the bottom usually means sludge. A failing pump or stuck valve can also leave radiators cold. We diagnose and restore even heat.

Will a power flush help?

If sludge is the cause, a flush plus a magnetic filter removes the build-up and protects the boiler. We assess whether it’s needed.
