Cold spots at the bottom of radiators, banging pipes or a boiler that keeps cutting out are usually signs of sludge build-up in your system. A professional power flush clears the corrosion and debris, restoring even heat and efficiency. We also design and install complete central heating systems, radiators, smart controls and underfloor heating.

FAQs

Central Heating — your questions answered

Straight answers to the questions we hear most. Still unsure? Give us a call — we are happy to help.

What is a power flush and do I need one?

A power flush is a deep clean of your central heating system that removes sludge, rust and debris using a high-flow pump and cleaning chemicals. If your radiators have cold spots, your pipes are noisy, or your boiler keeps cutting out, a power flush often restores efficiency and even heating.

Why are my radiators cold at the bottom?

Cold spots at the bottom of a radiator are usually caused by sludge build-up restricting water flow, while cold tops normally mean trapped air that needs bleeding. We can diagnose the cause and recommend whether bleeding, balancing or a full power flush is the answer.

How long does a power flush take?

A typical power flush takes most of a day, depending on the number of radiators and how much sludge is in the system. We will give you a clear price and timescale before we start.
