So, this is the situation ...
Toilet, two cubicles, two hand basins and a hand drier. As far as I can make out, and I've not had time for a really good poke about, but there's a spur from the ring main to the 1.9kW hand drier via a switched, unfused connector then carries on to a 1kW water heater via an switched, fused connector.
Now the water heater and drier have been there for at least 15 years and are showing their age; still work but the plastic is yellowing and I'm thinking of replacing them. If I move to an unvented undercounter water heater, it will look nicer and supply the two basins. Problem I've found is there seem to be very few low powered water heaters nowadays. Question to the expert on here, what power ratings can I go for before I seriously have to look at running more cabling?
