The immersion heater circuit in the airing cupboard of our house has at some point had a conventional dual-gang 13A socket spurred off it (used for a shower pump currently). I don't believe we have ever used the immersion heater so I haven't done anything about it until now (i'd wish to keep it though in case the c/h ever packed in). The circuit is fused at 20A and appears to be 2.5mm sq conductor cable.
I'm contemplating two things:
- Putting my tumble dryer in the airing cupboard too - where the combined loading may well exceed 20A if anyone did happen to flip the immersion heater switch while the tumbler is running.
- Having under-tile heating installed in the en-suite loo next door when the floor is re-tiled (it's a small room so not talking huge wattage).
It would seem pragmatic (and less costly for me!) for whoever I get to do the floor heating to continue to make use of the immersion heater circuit given how convenient it is, but is there a proper/acceptable way of doing this in regs?
I was thinking it *ought* to be acceptable to have a single-gang change-over switch (if there is such a thing - I've never seen one!). One way switches to the immersion heater's switched outlet, and the other way to the 13A socket and an RCD protected outlet for the floor heating).
Thoughts?
