Hi Guy's,
about four years ago we had an old potterton floor standing boiler (conventional) 30 years old replaced with a new Heatline condensing Combi (I know they are not the best boiler).
At the same time we had the the system powerflushed.
Now the boiler is struggling to get the water hot and only comes out slightly warm. We had a similar problem two years ago when the system needed a new diverter valve, I think either the heating was not getting hot or the water was not getting hot but it was not both together.
I had an engineer around and he stated that the heat exchanger in full of sludge from the system and he recons it is because the radiators are 35 years old the sludge is being produced from the rads rotting away from the inside.
He has suggested a Power Flush and to replace all the rads!
Could this be the case?
thanks
