Now the summer has nearly hit us and the heating has finally been turned off for the first time since we have had the combi fitted i'm realising another shortfall of not having a hot water cylinder in the airing cupboard. When we had the combi fitted I asked the installer to fit me a small radiator in the airing cupboard so we could still get some use from it...now of course the heating is off its useless! I was thinking about ways of somehow possibly wiring a stat in the airing cupboard in Parallel with the room stat downstairs and 2 valves so the heating will come on and just divert the water through the radiator in the cupboard and even possibly the rad/towel rail in the bathroom...is this kind of thing possible? what kind of valves would be available for this aplication, of course they would have to be electronic I would have thought and also would involve a bity of electrical trickery to pull it off but I think I can handle that side of things. Any one done this kind of thing before? Thanks for your help in advance!
