I have a Potterton Siuprima 30 boiler, it keeps stopping and starting every 30 seconds or so, radiators not heating properly and very little hot water. The boiler has had a new fan fitted 3 weeks ago and a new control panel about 3 months ago.
Would anybody have any idea what may be causing this?
The same guy, fitted the control panel and fan, but won't now return my calls
