What Is A Power Flush?
A power flush is a deep-clean for your central heating system. Over time, your pipes and radiators accumulate a mixture of rust, sludge, and limescale. This black debris creates blockages, forcing your boiler to work twice as hard to heat your home.
How It Works:
At Mayne Gas Heating Ltd, we connect a powerful specialised pump, high-strength magnets, and advanced cleaning chemicals directly to your heating circuit. This clears out heavy sludge and reduces future corrosion without needing to remove a single radiator.

Signs You Need a Power Flush
Radiators are cold at the bottom but warm at the top.
It takes an unusually long time for the house to warm up.
The boiler or pump makes a loud humming, banging, or rattling noise.
You regularly have to bleed your radiators, or the water comes out black/discoloured.
Certain radiators refuse to heat up at all.
