Power flushing in Chadwell St Mary, Thurrock.
Chadwell St Mary lies between Grays and Tilbury in the borough of Thurrock, close to Little Thurrock and Orsett. Its parish church of St Mary gives the village its name, but most of its homes were built during the twentieth century as the village grew, many of them family houses on its residential estates.
A heating system that has been in place for decades will usually have had a boiler or two replaced along the way, while the original radiators and pipework carry on. Over that time, corrosion inside the steel radiators produces black sludge, and Essex’s hard water adds limescale. The symptoms are familiar: radiators cold at the bottom, rooms that are slow to heat, a noisy boiler and bills that keep creeping up.
If you let a property, a sludged-up system can mean repeated call-outs and cold radiators over winter. A power flush deals with the cause rather than the symptoms, and the BS7593 compliance certificate you receive afterwards gives you a clear record that the system has been cleaned.
What happens on the day?
Most homes take a single day, around 6 to 12 hours in an average house, or longer where there’s microbore piping. Here’s what to expect:
- A Kamco power flushing unit is connected to your system, with a MagnaClean magnetic filter in the circuit to capture sludge as it’s loosened.
- Cleaning chemicals are circulated and each radiator is flushed in turn, with none of them disconnected.
- Once the water runs clear, the system is refilled and dosed with corrosion inhibitor.
- You’re given a BS7593 compliance certificate, and the work is covered by a 3-year guarantee, or 5 years with a MagnaClean filter fitted.
To keep the guarantee valid, the boiler needs servicing every year and the inhibitor topping up. We can look after the service for you through our Gas Safe boiler servicing.
