[QUOTE="binky, post: 549542, member: 490"] Adding up MCBs means nothing, that's just circuit protection. The electric boiler I installed for mum was 10kw, sufficient for about 6 radiators, and I assume you will be using the shower off that, it shuts down the heating side if drawing hot water. PCs usually around 500w for a powerful unit, so say 2 kw. Tumble drier 2.5kw, cooker usual runs at around 2kw max, because once it's warmed up, it draws less. Fridge TV etc around 1 kw max , kettle 2.5 kw but only for 10 mins, so rough numbers 16kw max, plus a few lights. 100 amp main fuse will cope with 20 kw ( it's roughly 4amps per kWh) so that leaves 4 kw to play with. I would be very surprised if you really needed an upgrade, and certainly not 3 phase. [/QUOTE]
