Power flushing

The core component of a heating system is the boiler. When a boiler is renewed, the boiler manufacturers Benchmark scheme requires that the system be thoroughly cleansed to the current british standard. currently the best practice is considered to be power flushing the system.

We use purpose built power flushing pumps designed to cure the circulation and boiler noise problems caused by the accumulation of sludge, corrosion deposits and scale that are found in most ageing central heating systems.

The power flush pump is temporarily connected into the heating system during the flushing process. The high water velocity combined with the instantanious flow reversal dislodges and mobilises sludge and corrosion deposits. After loosening the debris, the pump expels it from the system to waste using a high flow of fresh water.

Radiators are individually flushed without removal or disconnection from the system. After the power flush, the system is full of clean water and restoration to normal operation occurs after a few minutes.

A power flush can be extremely effective in cleaning systems with corrosion problems as a result of a design fault but we strongly recomend that any such design faults be rectified before the power flushing commences.

Thermoserv can carry out any inspection for these such design faults and advise you on the best cause of action before power flushing starts.
