Quote from: Chemistry4me on 06/05/2009 06:49:16Whoa! You thinking of making one Chem? If you are let me know and I may be able to offer some advice. First advice is do not use the copper connections with the solder already inside, they are crap and more expensive than the plain copper joints.
Karen, reckon I could have made it for £50.00 had I have had time to source the tubes and connections second hand. But the delay in saving on energy would have been counterproductive.I would go so far as to say this baby is as efficient as the heavily over priced thermal solar panels. So if it rains, we get free rainwater and when the sun comes out we heat it for free We like free.
Thank you Andrew!
Does the thread's title refer to the ex VAT price?:-)
