I have one 8.5kW shower in the loft, I was considering getting another one downstairs. The thing is, my single phase supply only has a 60A fuse, which runs into a 100A isolator then on into a recently fitted CU. It's a three bed house with loft extension and a garage/workshop.
My question is
a) Is it doable to have the two showers with a single phase supply? I wouldn't want to have to worry about say boiling a kettle when both happen to be in use, if it's fitted I'd want it usable at any time.
[The CU has 5 x 32A (upstairs ring, downstairs ring, loft extension, kitchen, garage - rarely used), 1x 40A (shower), 4 x 6A lights]
b) Is my supplier (EDF) likely to charge me a silly amount of money to change the supply fuse and/or take a very long time to get around to it? Does it involve changing the supply cable too?
TIA
