Is the point in using an electric boiler to heat water as well as it providing central heating so as water will get heated when the central heating is on, therefore surely giving some kind of saving over having the two completely separate. Of course it would only work like this when the two are asked to heat at the same time?
I need to choose sizes and don't feel oversizing the boiler is necessarily a good idea. My central heating requirement is going to be around only 3.5Kw worth. Going for a 6kw boiler seems then like it might be fine, stepping up to a 9kw one for example, seems like probably too big and maybe costlier to run.
Input appreciated. It'll just be getting used on a single rate electricity tariff. Thanks
