[QUOTE="Rich1982, post: 546989, member: 37074"] Not a DIY question as such, but a request for upgrading advice. I'm scoping out the costs involved in moving my home my away from fossil fuels and going fully electric. My concern is am I likely to need to spend a lot of money upgrading the existing domestic power supply to 3 phase in order to achieve this? I currently have a standard 80amp domestic supply (the main fuse states 80amp, the consumer unit indicates it is rated upto 100amps). My home is a standard 3 bed property containing the ordinary appliances (washing machine, tumble dryer, fridge freezer, kettle, microwave, etc). I currently have an electric oven and hob for cooking, plus an 8kw electric shower. Adding-in a heat pump with a max rated current requirement of 20 amps from the consumer unit; will that be feasible within the existing supply / consumer unit set-up, or will I need to factor in having the power system ugraded? I'd assume if an upgrade is required that would be to 3 phase, which I hear can be very expensive. Also, if this is feasible on the existing supply, if I then wished to add-in a charging point for an electric car at some point in the future could that realistically be accomodated as well? Apologies if these are stupid questions. With the push toward electric homes it seem unlikely that everyone is having expensive upgrades to 3 phase put in, but it feels like there may be a risk of getting close to the 80amps provided on the standard supply. I'd be grateful for any direction on this. [/QUOTE]
