Powerflush of heating system and fitting magnetic filter

I was advised by our boiler manufacturer that our central heating system needed a power flush to correct a boiler heat exchanger issue, which would then need to be changed. I contacted EVO along with several other companies and it was quite clear from the outset that EVO plumbing and heating had far better experience and technical expertise than any of the others. The work was carried out exactly as described, in a very professional, clean, and commendable fashion. Now the powerflush is complete, not only is my heating now hotter and more efficient than ever, but it also seems to have fixed the issue with the heat exchanger!

Powerflush heating system and fit magnetic filter

Quality service from a company that really know their stuff. Previous people had been unable to diagnose and rectify problem. Called on Harvey from EVO after a personal recommendation from a friend. We now have full heat throughout house.

Powerflush heating system to improve heat distribution

Steve and EVO originally came to fix a circulation problem with heat not getting to all radiators. Steve diagnosed a powerflush was required, and I must say our house has never been so warm!. Excellent work!

Reducing energy bills and the risk of boiler breakdowns in London

Is your radiator cold at the bottom? Perhaps you have a noisy boiler? Extend the life of your boiler and heating system with EVO Plumbing and Heating Services, covering London. Not only will power flushing help to keep heating bills down, it also reduces the risk of breakdowns by removing magnetite - a sludge-like substance that is made up on dirt, mites and corroded metals.

What is power flushing?

Power flushing is the specialist process of forcibly cleansing a heating system with water. Whilst it sounds quite simple, the water must be applied at high-velocity and low-pressure so that no physical damage is caused to the system. The purpose of power flushing is to restore systems to optimum operation; improving overall circulation and resolving boiler noise issues.

Powerflush to restore heat on first floor

Delighted with the service we received. 2 other companies had failed to remedy our heating problem. Called EVO out of desperation who attended and gave a free site visit. They immediately identified the problem as heavy sludge in the pipe circuit and recommended a powerflush. The staff were professional, friendly, and courteous throughout, and the results are first class - our heating has never worked so well. I thoroughly recommend EVO.


Was expecting a messy job with major upheaval. Delighted to say that wasn't the case at all, and results and pricing were absolutely superb.

Power Flush of Heating System and New Pump

Worked Hard all day from 9.00am to 6.00pm. Radiator system 35 years old at least. Corgi Home Plan engineer was unable to get Boiler working despite 2 visits. Told Corgi would not cover system if blockage was the cause. Colin did the work at short notice and phoned 4 days later to ensure all was well.
