POWERFLUSHING !!! 

Its that time of year where everyone puts on their heating and suddenly finds out that radiators are just not getting hot enough and seem to have cold spots in the middle. This is all that lack of circulation in summer and the phosphosrus sediment sitting there. This causes untold problems with pumps being strained, rubber seals getting ATE !! yes ate the "sludge" is no having a negative effect on the whole system. 

So when you get it powerflushed its clears that rubber eating hydrogen gas producing sludge out of the system and leaves your system in the best possible state it can be with some nice inhibitor chemicals added to reduce the onslaught when the next summer comes around
