Power Flushing Central Heating Systems

Power Flushing Central Heating Systems
Power flushing is a more efficient and quicker way of cleaning a central heating system. It consists of flushing through the entire system using water and a reputable cleaning agent. It is done at high velocity but low pressure so that no physical damage is caused to the system.

Fitting new boilers
When installing new boilers in an old central heating system it is important that all of the sludge is first removed from the system as it could accumulate in the new boiler.

Central heating system problems - poor circulation, boiler noises?
In hard water areas old systems will have accumulated lime scale and corrosion deposits, which can affect the efficiency of the boiler. Power flushing will break up hardened deposits allowing them to be flushed away easily. This procedure restores central heating systems to optimum efficiency.

How we Power Flush an existing central heating system
The central heating pump is removed and the flushing unit connected between the pump valves. The unit has its own powerful pump. We add a cleaning solution and flush through the system.

A thorough system clean takes 3-4 hours from set-up to completion.
