Powerflushing for Cold Radiators
If your radiators are cold at the bottom, slow to warm up or not heating at all, your system may be full of sludge. A powerflush pushes clean water and cleaning chemicals through the whole system with a dedicated machine, lifting out the build-up that stops heat reaching your rooms.
A clean system heats up faster, puts less strain on your boiler and can help it last longer. It is often the right first step before a new boiler is fitted, and we will tell you honestly whether your system needs one.
