The Importance of Electricity in a Large House

Three phase does make a lot of sense right yes but it's not correct to say that it's absolutely necessary or compulsory no. Anything with a straight out heating element that just heats stuff up air or water or whatever is going to use a lot of electricity and so things like kettle that that uses a lot but not for a very long time. A third of the energy use of my home is hot water which is why i'll put systems in place now to divert solar my solar during the day into my hot water tank and use it as a thermal battery far more cost effective than buying a home battery battery I might add.
