we recently completed a central heating power flush in stafford , system was a combination boiler system with 9 radiators ,most noticable thing about this job was the ph and tds levels were very high which would make limescale and corrosison a major problem in these areas,indeed the customer told me that she had recently had the secondary heat exchanger changed for a brand new one as the last one had failed ,,it may have actualy flushed through and resolved the problem if we had been given the chance to flush it previous to it being changed ,,apart from that the flush was successful all radiators were hot and up to temperature again by the time we had finished ,,so if you need any power flushing done in stoke ,staffordshire or the wolverhampton area give me a call on 07836 353 985 or see website for more details and you can view our video below
