No matter what fuel source is used the build-up of sludge in a hot water central heating systems is inevitable. Power flushing will remove the sludge and scale from your system, which will have built up over a period of time.
This sludge can block pipes and prevent the radiators from distributing heat around your house. Therefore power flushing your system will make the boiler work more efficiently.
Before having a new boiler installed it is imperative that the central heating system is power flushed before any other work commences.
Failure to have the system power flushed first will invalidate any boiler manufacturer's warranty, so beware of other companies who may offer you a cheaper quotation for a boiler installation. We advise that you check exactly what is actually included in all quotations.
