Energy Efficient Boiler regulations??

[parkers]

Can anyone please tell me what type of boiler is required to be fit in new properties, as in combi? Condensing? SEDBUK A? B? C? As regulations state?

Thanks

New properties (in England /Wales) have to have a SEDBUK A or B boiler installed. This defines the efficiency by which the boiler converts the fuel into hot water - A being the best. Not sure about other parts of the UK - may be the same. With very few exceptions, only condensing boiler achieve this efficiency. Look for the SEDBUK number - every boiler has to have one. A combi is a type of boiler that provides hot water as it is demanded - it doesn't put hot water into a storage cylinder like a conventional boiler. You can have condensing combis and condensing conventionals.

Excellent, thanks.

Looks like I need to be having a conversation with the company building our house as they are trying to tell me that "as the plans were submitted before Apr 05 it is ok for them to install a SEDBUK D rated boiler"....

Thanks again

That is true - the same situation applied to me. Its the date that Building Regs approval was originally granted that is important, not the date of boiler installation or final sign-off of the house. Whether you wish to push for a condensing boiler is your call, but your builder may want to charge a bit more because they are more expensive. In the long term it will save you energy (money) but the reliability of them is unproven - there is more inside them to go wrong.
