We have the renewable heat incentive up here but really not sure how it pays back, one of our neighbours in a very similar property is an architect, he has looked at it all and hasn't changed a thing so far. Heat pumps are just air conditioners in reverse so don't spit out any electricity but the coefficient of performance is always above 2 or 3 I think, meaning 1 unit of electricity will produce 2 - 3 units of heat but requires a plumbed in central heating system which we don't have.

Can an air source heat pump generate electricity or will it just spit out heat? When I used to work on sustainable building magazines it was all ground source heat pumps, wind turbines and solar panels, batteries were still a pipe dream... There must be grants for this kind of stuff up in Scotland, no?
