The standard supply for a new house seems to be circa 18KVA single-phase. I have a client who needs to make application for a supply for a new build house at 400m2 with the only certain information being that an air source heat pump is to be used for heating. The client simply does not know what the electrical loading might be. The house is only coming out of the foundations but the DNO supply may take many months as the house is in a relatively remote rural location, thus loading details are required before the DNO will consider progressing the proposal. It is a big house, but that is what it is, just a big house. I am inclined to advise a standard supply but 3-phase as with a large AS heat pump, maybe shower, cooking and perhaps an EV or two, 18KVA wouldn't be long being gobbled up. As we move towards a higher reliance on electric as a power source for some heavy current-using equipment, it might be that 18KVA is no longer a realistic standard supply for even the smaller property.
Building technology has moved along quite substantially in the last 15 years or so - new builds are now incorporating levels of insulation that a generation ago were thought to be physically almost impossible and increasing fuel prices and likeley future fuel scarcity are making high levels of insulation more and more attractive, especially in the self-build sector (what will you run your gas boiler on once North Sea gas runs out?).
Coal gas! ?
It's a bit windy here today, so the windows are rattling. That certainly wouldn't happen in a new build. When I first heard about pressure-testing new houses, I thought that somebody was having a giraffe, but no, 'tis true. That is despite the presence of open chimneys, ventilation bricks and, of course opening windows. ?
