What is power flushing?

Power flushing is a rapid, comprehensive and forcible cleanse of a heating system using high-velocity, low-pressure water. The goal is to flush out magnetite, which is the black sludge held in the water of a heating or hot water system. It is possible that you may have encountered this mixture of dissolved metal in the lower parts of your heating system such as the basement or ground floor.

The process does not damage your heating system. Power flushing equipment connects to your heating system and cleans the radiators, pipes and boiler thoroughly. At the end of the process, after all the sludge has been flushed out, an inhibitor fluid is added to reduce chances of or postpone future contamination.

Aaron arrived bang on time, was painstaking in his work, although young he had rare old school ethics and wanted my 40-year old Potterton boiler de-scaling to be perfect. Took extra time to see it spotless with courtesy. A huge credit to his company.

My shower had stopped working and I needed someone to come and look at it quickly in this heat! Evo were very helpful and got the job done quickly too. Brilliant service, can’t recommend enough. I’ve booked them to come back again to look at a boiler issue I’ve been having. Really pleased, it’s so hard to find decent workmen these days.

Is power flushing needed in my home?

Certain signs indicate that power flush is required sooner than later:

  • A slow warming system
  • Cold spots on radiators
  • Radiator does not heat u fully
  • Some rooms in your home are cold
  • Radiators frequently need bleeding
  • Bleeding the radiators reveals discoloured water
  • Excessively noisy boiler
  • Heating system produces little or no water

Even if you experience only one of the above issues, follow it up to understand and resolve the underlying problem speedily for the reasons stated below.

The benefits of power flushing

Periodic power flushing preserves the efficiency of your heating system, keeping every room in your home comfortable and your fuel bills low. You can also keep corrosion at bay and extend the life of the system.

A faulty heating system can be a big bother during the cold months. Moisture condensing in winter can increase dampness and mould formation, triggering episodes in allergic or asthmatic family members. An uncomfortably cold indoor environment can also affect heart rate and blood pressure.

If you haven't scheduled a power flush in a long time, get it done today.

Power flush C.H. system.

2024-07-01

Arrived on time, courteous and tidy. Checked what needed to be done then worked through job efficiently. Showed the iron sludge extracted in the machine and refiled system with inhibitors then ran up to temperature, demonstrating the improvement in the worst problem radiator. Completed job on time. Since the work required access to most of the house its nature is quite invasive but this was handled well. Many thanks.
