does electricity cost more per unit on a 3-phase supply? I know it costs more to install, just wondered if it cost any more on the bills, as it is usually reserved for commercial rate customers. Is it freely available to domestic installs (if you ask, will you get it without a struggle?)
I was just wondering, because with the rate things are going, many new homes will be heated/cooled by electric heat pump air conditioning units soon, and obviously 3-phase units are easier to get hold of by big housing companies etc. Also, big power showers may turn 3-phase soon so they can be more powerful (20A across 3 phase = 60A so a 13.8KW shower ), and with part p2 (prediction), only qualified lectricians will be able to service them/replace them (being 3-phase, its not a DIY job)
As an alternative, is 2-phase available in this country? i mean, is it possible to tap off 2 phases to each house rather than 1 or 3? Do 2-phase air conditioners exist? I think the american system of 2-phase and neutral is good, with 240V washing machines and air con units, though im sure this has its downsides that the experts on here will tell us about!
Just hypothesising for the future of UK household electrics. feel free to comment!
