Power flushing in Croydon for every kind of home.

The London Borough of Croydon covers a lot of ground, and its housing changes as you travel across it. That matters for your heating, because the age and layout of a house shape how its system was installed and how much it has been altered since.

  • Thornton Heath, South Norwood and Norbury: streets of Victorian and Edwardian terraces, where central heating was added long after the houses were built
  • Addiscombe and Shirley: a mix of Victorian, Edwardian and inter-war houses
  • Purley, Coulsdon and Sanderstead: mostly inter-war and post-war semis and detached houses in the south of the borough
  • Central Croydon: flats, offices and shops, from converted older buildings to recent blocks

Why older systems clog up.

Most heating problems start inside the system. Steel radiators slowly rust from the inside, producing a black sludge, and London’s hard water adds limescale, which builds up in the boiler. Systems that have been extended over the years, with extra radiators or new pipe runs, give that debris more places to settle. The result is the familiar set of symptoms: radiators cold at the bottom, dirty water when you bleed them, a noisy boiler, and heating that takes ages to warm up.

What a power flush involves.

We connect Kamco flushing equipment to your system, so no radiators need disconnecting. Cleaning chemicals are circulated to break down the deposits, a MagnaClean magnetic filter collects the sludge, and a corrosion inhibitor is left in the system at the end. An average home takes 6 to 12 hours. Microbore pipework, common in systems fitted in the 1960s and 70s, takes longer.

We work on commercial premises too, from shops to offices; see our commercial work. Every job comes with a BS7593 compliance certificate and a 3-year guarantee, extended to 5 years with a MagnaClean filter fitted (an annual boiler service and inhibitor top-up are required). Our engineers are fully trained and DBS checked. If you let a flat or house in the borough, we work with your tenants on access but deal with you directly, and the paperwork and guarantee are emailed to you.

What our customers in London say.

  • I was very surprised at how much better our heating system worked after Darren completed the power flush. We live in a big house with 16 radiators and the difference has been incredible. Our heating bills have gone down by at least 20%.

On the day

What happens during a power flush.

It’s far less disruptive than most people expect.

We need access to your radiators, pump and boiler (and the loft if your tanks are up there), and most homes are done in a day.

  1. 01

    We connect the power flushing machine

    Your engineer attaches the machine to a single point in your system, usually the pump, and circulates clean water and cleansing chemicals.

  2. 02

    Each radiator flushed individually

    Where it’s needed, radiators are flushed one by one to shift stubborn sludge and blockages.

  3. 03

    Flushed until the water runs clear

    The loosened sludge is drained away safely and cleanly, and we keep going until the water runs clear.

  4. 04

    Scale and corrosion inhibitor added

    Your system is refilled with clean water and an inhibitor that slows future corrosion and build-up.

  5. 05

    Rebalanced, radiator by radiator

    We balance the system so heat reaches every room evenly and your boiler isn’t working harder than it needs to.

6–12 hours in an average home, longer with microbore piping

3-year guarantee on every power flush, or 5 years with a MagnaClean filter

    Mr & Mrs RowleyEmerson Park

  • Power flush and filter fitted. Very pleased with work - radiators hot again. Cleaned amazing amount of sludge from boiler! Half price of British Gas quote. Would not hesitate to recommend.

    Jeff

  • Our engineer was fantastic, our microbore pipes were solidly blocked but he managed to get the heating working better than it ever has done while we have lived here! Thank you!

    Jessica PColchester

  • There was far more sludge than expected and as a result the engineers stayed until 11pm to get it all out and fit a Magnaclean. In spite of this, the invoice was for the exact amount of the estimate given over the phone and significantly less than that of the previous firm.

    Archie CampbellCambridge

  • Darren was a very friendly chap did a fantastic job radiators now heat up within 5 mins of switching on. He persevered as the system has never been power flushed before, even the radiators that didn’t work. Well recommended and I like the fixed price, you know what you pay.

    AJ

  • The flat has never been so warm, I have happy tenants. I will be using Power Flush Wizard to clean the radiators in all my rental properties in future.

    Nicola GrantRochester

  • My boiler was making lots of noise and cutting on and off and I wasn’t sure why. I called the Power Flush Wizard and their heating engineer quickly identified the problem. After a power flush of my heating system I could not be happier with the service I received and the resulting reduction in my fuel bills.

    D CarpenterSurrey

  • May I take this time to express how impressed we were with Darren’s customer service and knowledge. We will definitely recommend Power Flush Wizard to friends and family and also use your services in the future.
