To improve your central heating efficiency you need to ensure that the inside of your central heating system – the part you cannot see – is as clean as it can be, allowing the water that flows around it to do so without the problems associated with sludge deposits that build up in radiators or lime scale deposits that build up on any metal surface – inside the radiators, around the pipe work and even on the heat exchanger in your boiler.
