Are you having any problems with your central heating system such as noisy pipes, low hot water pressure, radiators not heating up properly or taking too long to heat?
This may be the result of sludge and limescale build up within your system, which can slow or block hot water from moving through radiators efficiently resulting in cold spots and inefficient heating. A power-flush will remove any build up in your system by sending high pressured water through the heating system, flushing away any debris.
