Can anyone help.....please!
I have several problems with my central heating system but cant quite establish exactly what the causes are or if they are related. Any advice would be appreciated.
1. The hot water at the kitchen tap is too hot despite the hot water tank thermo being on the lowest setting.
2. Very very hot water regularly flows back into the loft c/h water tank.
3. The radiators are never all hot at the same time. Some remain cold. This cold radiator problem seems to move around the house. On bleeding the cold radiator, cold water and not air comes out.
4. Sometimes the bottom 2/3 of some radiators remain cold. Not just in the middle bottom but across the entire radiator.
5. The boiler (Potterton 5 years old and in very good condition says BG) fires up then immediately switches off and the green lights flashes.
BG tell me a Powerflush will solve the problems and make the whole thing better.
Sorry about the tome but your help is appreciated.
