An electric boiler is never going to deliver more energy then the energy you put in to it (in the form of electricity). A heath pump can because it extracts heath from the air (or better said the water in the air). Now if this were in France with a modern grid and nuclear power it might stand a chance. But the UK with it's aging grid and aging power plants? I doubt it.
