What are the signs that you may need a power flush ?
There are many signs that your system maybe suffering from a build-up of what the industry refers to as ‘sludge’.
Cold spots at the bottom of the radiator – sludge and dirt settles at the bottom of the radiators in little piles and as they build up the cold spots get bigger
The heat transference of the radiators system is reduced
Radiators stay warm or cool but the pipes are hot
Radiators need bleeding and the water is noticeably discoloured
The system makes a banging or knocking sound, this can come from the boiler or radiators/pipes
Boilers overheat because they have to work extra hard to heat the home
Boilers can ‘whistle’ as parts of it overheat or cycle on and off as the overheat stat continually cuts in
For combi boilers you may notice only warm water from the taps as the heat exchanger become blocked on the system side by dislodged debris
