Power flush (radiator flushing) in Guildford
Radiator flushing is normally completed by carrying out a power flush or sometimes by a chemical flush. If you have a noisy heating system, cold radiators or repeated pump failure it is quite likely that your system needs a power flush. When we power flush your radiators we will drain your heating system, connect our machine normally to the pump connections then refill. We will circulate strong chemcals through your system with the boiler on and radiators turned off. Once the main pipework has been cleaned we will then carry out individual radiator flushing, this will be repeated until the system is clean.
Once your system is clean we will refit the pump presurise the system and check for leaks. Once we have checked this we will then balance the radiators until each is a good temperature. If you have a boiler fault sometimes companies recommend a power flush without looking into the boiler fault which may not be related. It is best to get a second opinion if a company offers you a powerflush, in our experience it can be relating to a faulty pump or sticking thermostatic radiator valves. If your pipework is completly blocked it may require replacement as a powerflush will not be possible to clear a complete blockage.
Kamco is the powerflush manufacturer we use and is the only machine we recommend using.
The CLEARFLOW power flushing pump is simply connected into the heating system, either across standard circulator pump couplings, across the tails of one radiator, or wherever most practicable. The powerful flow, combined with instantaneous flow reverser device, will dislodge and mobilise deposits and corrosion which resist traditional system cleaning methods. Once the corrosion and sludge deposits have been loosened and mobilised, fresh clean water is forced through the heating system, pushing the contaminated water out through a full bore dump valve to waste. During the CLEARFLOW process, radiators are individually flushed, without removing or disconnecting them from the system, by directing the full output of the pump through each radiator separately. At the end of the flushing process, the system contains fresh clean water and reinstatement of the system to normal operation takes only a few minutes. System flushing will not remedy design or mechanical faults, which should be rectified, but in many cases it will cure the problems caused by these. | ![]() |
