Hi,
I've recently had an energy survey done on my house and it has come out a very poor 'F' rating. I have all the usual loft and wall insulation together with double glazing and the like, what I have been told is that if I replace my 20 year old Vaillant VCW GB 221 LPG boiler for a modern quality boiler I could raise my rating to a 'C' but in the real world how much more efficient is say a Worcester Bosch combi boiler?
Regards Marc
