Signs your Chelmsford heating needs a power flush.

Most of us don’t give the water inside our radiators a second thought until something goes wrong. The warning signs tend to creep up over a few winters, so they’re easy to miss:

  • Radiators that are warm at the top but cold at the bottom, or have cold spots
  • Black or brown water when you bleed a radiator
  • A boiler that bangs, gurgles or whistles, or pipes that knock
  • The boiler cutting out and needing to be reset
  • Rooms that take much longer to warm up than they used to
  • Heating bills rising even though you use the heating the same way

Most of these point to sludge. As the steel inside radiators slowly corrodes, it forms black iron oxide, which settles where the water moves slowest and eventually starts to clog the boiler. Chelmsford, like the rest of Essex, has hard water, so limescale can build up alongside it.

Power flushing in Chelmsford, from the centre to the villages.

Chelmsford became a city in 2012, and its homes cover a long stretch of history: Victorian terraces near the centre and in Moulsham, established suburbs such as Great Baddow, Springfield and Chelmer Village, and newer developments on the city’s edges. Villages like Broomfield, Writtle and Galleywood add older cottages and family homes to the mix.

Whatever the age of the property, the process is the same. We connect a Kamco power flushing pump, circulate cleaning chemicals through each radiator in turn, and capture the loosened sludge with a MagnaClean magnetic filter. No radiators need disconnecting. When the water runs clear, the system is refilled with corrosion inhibitor and you receive a BS7593 compliance certificate. Most homes take a day, around 6 to 12 hours, or longer with microbore piping. If you’re weighing it up, our page on why a power flush is worth it covers the reasons in more depth.

We also work with landlords on rented homes, and carry out commercial power flushing for business premises.

Based in the Chelmsford district.

Our base in South Woodham Ferrers sits within the City of Chelmsford district, so Chelmsford is a short drive away. We also cover nearby towns such as Maldon and Witham. Our engineers are fully trained and DBS checked, with public liability insurance up to £5,000,000, and we bring over a decade of power flushing experience.

Every power flush comes with a 3-year guarantee, or 5 years with a MagnaClean filter fitted, as long as the boiler is serviced every year and the inhibitor is topped up. A clean system can cut heating bills by up to 25%. Call 0800 3277 448 for a free, no-obligation quote, or try our online estimate. Booking online qualifies you for a free £25 pump service.

What our customers in Essex say.

  • 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!

  • 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.

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

Testimonials

What customers say about our power flushing.

We’re proud of the feedback we’ve received from homeowners, landlords and businesses.

  • 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%.

    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.
