My boiler is 90% efficient; there is almost no room for improvement.


Truth: A “heat pump” can produce 4 units of heat for every unit of electrical input. Thus by a conventional definition it is 400% efficient, a big improvement on your boiler! (To avoid confusion, a different measure of efficiency called the Coefficient of Performance, or CoP, is used in heat pumps).


However, the really large fuel bill savings will come from insulating, airtighting and replacing windows in a house to mean that the boiler (or heat pump) does not have to produce so much energy in the first place.
