I recently got my whole central heating system changed (replaced the old boiler to a Potterton Suprima, and repositioned the boiler and changed all the radiators as part of building an extension). Now I faced with 3 issues and could some one advice?
1. Getting water flow noise (gurgling sound) whenever the central heating system is switched on
2. Upstairs radiators from time to time (more or less weekly) reqires bleeding to get rid of the air
3. Whenever the hotwater is swiched on the radiators are getting hot too
4. Hot water is getting very hot in the taps
Sorry for the long list as I have already spent over Â£3000 and worried that whether the whole thing a mess!
