It has taken me a month since I moved to my new flat to work out how to activate the boiler that supplies hot water to the taps. The name on the boiler is 'Zip Aquapoint III'. Here is a photo I took, using a torch for illumination, since it is installed in an inaccessible place at the back of the cupboard under the sink.This is a type I have never encountered before.
I looked up the make on the Web to find instructions, but they mostly covered installation. There was mention of an 'economy' setting, which appeared to be by moving the circular panel round to the first white dot, but that didn't seem to have any effect. It has taken me a couple of weeks to find a small white switch, right at the back of another cupboard, which switches it on!
There are other more prominent red switches, one of which activates the electric hob. What the other does I have yet to find out. Possibly it is to do with the shower. Meanwhile I have managed to boil up hot water using the electric kettle. Previously I've always used a gas hob for cooking, so an electric hob is unfamiliar and will take some time to get used to. It doesn't help that it is totally black, including the knobs, and not illuminated by the ceiling lights.
