[QUOTE="binky, post: 553738, member: 490"] I see what you are saying, but somehow those numbers don't feel right :) . Direct heating water, and a quick scan suggets 70-80% efficiency of thermal panels, seems a straight forward simple solution. All you would need is some panels and a pump. I also think solar thermal is still eligible for RHI payments - that scheme never caught on like the FiT payments for PV and I think it may still be open. I have a customer who uses a heat pump for his swimming pool, far cheaper to run than the all electric heating he had, but he had no space for thermal panels. So I would suggest it all comes down to cost of a large heat pump v cost of thermal panels. One question, how often do you get the full CoP of 4.5? [/QUOTE]
