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.
