FAQs

What is power flushing, and how does it work?

Power flushing involves pumping cleaning chemicals through your central heating system at high velocity to remove internal sludge and debris.

How often should I power flush my gas system?

We recommend every 5–7 years, or if you notice symptoms like cold radiators, dirty water, or boiler noise.

Will it damage my system or pipework?

No. Our experienced engineer in London uses safe, regulated equipment designed specifically for domestic gas heating systems.

Does it make a difference in performance?

Absolutely. Power flushing restores heat distribution, improves boiler efficiency, and can reduce energy usage.
