Greetings and Bonne Annee, folks! We have just completed on a house in Brittany, and intend to move by mid-January. The property is separated electrically and has two electricity supplies (two meter boxes, etc, and presumably two separate bills) which each feed half of the house . One (the modern circuit) is triphase, the other monophase (this circuit needs renewing) We need to set up an account with EDF for the triphase supply side - and eventually will have the other part rewired and joined up to make one supply for the whole house. The water heater and oil boiler I assume are triphase appliances (we may need to replace both soon) - a key consideration, and why I'm dithering about this! My questions: can anyone advise on weather it is best to keep the triphase, or change to monophase? Why? most of our appliances and electrical equipment will come from the UK - can we just plug these into a triphase curcuit. Will they work ok? I have seen other threads discussing the triphase/monophase topic but not found the answers I need. I will very much appreciate any help offered. Many thanks
