When we have our new boiler fitted (later this summer) we have been advised to use our immersion heater for a few days. Problem is that it's plugged into a 13amp socket in the airing cupboard and hardly ever used. Can I use a timer in there for a week or so or is that dangerous?
All the ones I've seen say not for immersion heaters but I reckon it will actually be timed on for about 4 hours each day.
