Power Flushing in Newquay & Cornwall

Boiler Power Flushing

At MG Plumbing & Heating SW, we offer professional power flushing services across Newquay and the wider Cornwall area. Power flushing is a highly effective way to clean, revitalise and protect your heating system — improving efficiency, prolonging boiler life and ensuring consistent, reliable heating throughout your home.

If you're looking to improve the efficiency of your boiler as well as prolong the life of your heating system, we can carry out a power flush. Over time, heating systems will get a build-up of sludge, this sludge can create cold spots in your radiators, meaning that the heat cannot flow through them effectively and thus your home will take longer to heat.

A power flush involves a machine and chemical process which removes this sludge from your system and replaces it with clean water. If you would like any further information on a power flush or how to identify whether this would be beneficial to your heating system please contact us to discuss.


Why Power Flushing Matters

Improves efficiency – Flushing removes sludge, rust, limescale, and debris buildup that block heat flow, helping radiators heat up faster and heating stay consistent.

Protects your boiler & radiators – Prevents damage to boilers, pumps and radiators caused by corrosion and sludge buildup.

Saves energy & reduces bills – A cleaner system runs more efficiently, helping you save on fuel costs.

Fixes problems – Helps remedy cold spots, noisy radiators, slow heat-up or uneven heating.

Extends boiler lifespan – Regular flushing keeps the entire heating system healthy for longer.

What Our Power Flushing Service Includes

System Assessment

We begin with a comprehensive inspection of your heating system — checking radiators, boiler, pipework and identifying any problem areas.

Safe Draining of the System

We drain the existing heating water safely and responsibly before starting the flush.

Power Flush Process

Using professional flushing equipment and cleaning chemicals where needed, we flush out sludge, rust and debris throughout the system — boiler, radiators and pipework.

Refill & Inhibitor Treatment

Once flushed, we refill the system with fresh water and add corrosion inhibitor to help protect against future sludge, rust and scale build-up.

System Check & Balancing

After refilling, we check flow rates, pressure and balance the system so that radiators heat evenly and efficiently across your home.

Post-Service Assessment & Advice

We carry out tests to ensure the system is functioning correctly. Then we advise on maintenance, recommend scheduling regular checks, and offer guidance to keep the system healthy.

Testimonial 1

Highly recommend Martin and his services. Quoted promptly and competitively for a new combi boiler with a hive system. Agreed on a start date which went ahead and over the 3 days never found him to be any less than professional. Areas left clean, and tidy with minimal disruption. Stayed and ensured we were happy with operating the boiler and hive system and explained his follow-up process.
Would have no issues in recommending Martin for any works.

Absolutely superb!!
Martin installed a whole new heating system for us, a boiler and radiators with Hive, and then a shower and new bath taps at a later date. He is speedy, efficient and well-priced. Gave us lots of useful tips and advice and is always available for any questions. We couldn't be happier with our decision. Thanks so much.

Our central heating boiler failed over Christmas, phoned Martin the following morning and as promised as soon as the supplier re-opened sourced a new boiler and fitted it the following day.
He was punctual, very professional and gave excellent service, we have no hesitation in recommending Martin.
