What is a system flush and do I need one?
When the boiler is replaced, it is important to make sure that the system is cleaned and treated. A clogged up system will not allow the full efficiency of the boiler to be met, meaning that more fuel will be needed to heat the home. This does not need to be performed annually, but is useful every few years. If you notice that the radiators are ‘cold spotting’, then it is probably time to have a system flush.
