Sludge, flakes of iron oxide and other debris builds up at the base of a radiator
Cold spots are formed because the sludge inhibits and prevents the natural flow of water around the system
Areas that are not affected can radiate heat normally
Why a power flush may be necessary
Over time small flakes of iron oxide (rust) from the radiators and other debris given the descriptive term of sludge can build up internally in a central heating system. Its especially evident in older central heating systems although it will build up in most systems given enough time.
The problem is compounded by the fact that within a central heating system and particularly a boiler there are fairly minute channels which water must pass through in order to circulate. If these are blocked the boiler will simply not function effectively.
How blockages in a central heating system are manifest
A power flush is utilised to do just as it says, to flush out the sludge and flakes of rust within a boiler and central heating system which may be preventing the optimal flow of water around the system and thus indirectly affecting efficiency..
Ways in which the problem of a blocked system may be manifest are cold radiators that do not respond even after having been bled. Poor circulation on the central heating system leading to over heating and/or heating but no hot water. Blocked pipes which restrict the flow and return of water through the central heating system. A pump that is struggling to move water throughout the system resulting in unacceptable noise. Blockages internally in the boiler and in the heat exchangers or internal pipes.
The results of a professionally delivered power flush are increased pump life as the pump does not have to struggle against blockages caused by sludge and debris. A full spectrum of heat from radiators with no cold spots to diminish its efficacy. The removal of debris from the boilers main or plate heat exchanger which in themselves can be costly to repair and replace especially the main heat exchanger. A reduction in corrosive gases which may form and reduce the optimal heat output of your system.
A powerful filtration system
Water is channelled through the system where it is filtered until crystal clear and free from any contaminants and/or debris. The power-flush literally flushes cleansed liquid through the system until it is clean and free of sludge. Once the power flush is completed a 24/7 heating solutions Gas Safe Engineer will refill your central heating system and add a corrosion inhibitor to prolong the operating life of your boiler and heating system.
