Power Flushing

Heating systems can get clogged up

Over time, black sludge produced by corrosion can build up inside heating systems. This hampers the efficiency of the system and eventually renders it virtually useless at heating your home. The bore (internal size) of the pipes is reduced, making it harder for the pump to push hot water round the system. The boiler heat exchanger becomes clogged, resulting in longer heat-up times for your radiators and longer recovery periods for the hot water tank (the time it takes to make a new tank of hot water when you've used it all). Eventually the radiators themselves start to sludge up and keep a cooler patch in the middle, even when the system is hot.

Clogged systems cost more to run

Not hundreds of pounds more, but if we think about an example: a sludged-up boiler and pipework that takes 35 minutes to heat a tank of water to your required temperature, could have taken only 25 minutes to heat to the same temperature if it was free from sludge etc. This means that the boiler is not only working harder but is using gas for 10 minutes more each time you need to heat a tank of water or the radiators from cold. Even if the boiler is only switched on once per day, it's still over an hour's unnecessary gas consumption per week. Add to this the fact that the other components of your system like pump, diverter valves etc give up the ghost prematurely, not to mention the detrimental effect on the environment.

Clean out with a power flush

Sometimes, a 'power flush' is the only option before replacing pipework etc. if you decide to have one done, I have a top-of-the-range Kamco flushing unit that can power water and chemical through the system in both directions at the flick of a lever. It is a clean, quiet process and through the transparent hoses that I use, you can see the contents of your system end up in the swirl tub and then be ejected out of the discharge hose down the drain.

System restoring chemical is then added and the system put back into use.

The flush-out will take around 3/4 of a day, depending on the size of the system, the number of radiators and the severity of the sludging.
