Older homes by the sea in Harwich and Dovercourt.

Harwich has plenty of older property. Old Harwich, where the Stour and Orwell estuaries meet the sea, keeps its historic street pattern of closely packed period houses, while Dovercourt grew as a Victorian seaside resort with its own terraces and villas. Parkeston, home to the international port, sits just upriver, and the villages of Little Oakley and Ramsey are close by.

Heating in older properties tends to be a patchwork. Many period homes had central heating added long after they were built, with long pipe runs, radiators added room by room and, in some cases, microbore pipework from a 1970s or 80s installation. Systems like these collect sludge as the steel inside slowly corrodes, and Essex’s hard water adds limescale. The results are easy to recognise: radiators that never fully warm up, a boiler that gurgles or cuts out, and water as black as ink when you bleed a radiator.

Power flushing in Harwich: what’s involved.

A power flush cleans the system where it stands. 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, which helps in an older house where fittings may be fragile. When the water runs clear, the system is refilled and protected with corrosion inhibitor, and you receive a BS7593 compliance certificate.

Most homes take a day, around 6 to 12 hours, and longer where there’s microbore piping, so it’s worth mentioning if you know your house has it. The work is covered by a 3-year guarantee, or 5 years with a MagnaClean filter fitted, provided the boiler is serviced every year and the inhibitor is topped up.

We work with:

  • Homeowners in period cottages, Victorian terraces and modern houses
  • Landlords with rented houses and flats
  • Businesses and other premises, through our commercial power flush 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!

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.
