Powerflushing is where a high pressure two-way pumping machine is connected to the flow and return pipes of a central heating system. The pump blasts water containing added cleansers through the system at approximately 100-150 litres per minute, that's about 10 times faster than the central heating circulator pump. The dirt is then pumped to a waste outlet and freshwater is pumped into the system thus removing sludge and debris that blocks the heat exchanger, pipes and radiator valves.
This technique will resolve many problems associated with radiators not heating up, cold spots, etc. Once the system is clean, inhibitor is added to the system to prevent further formation of magnatite thus protecting and prolonging the life of the system and restoring energy efficiency.
Prices for this service start at £350 including cleanser & inhibitor for an average sized three bedroom house.
