Hello All... it's been a while since I have posted but I need some help and don't know where else to turn.
I have bought a used American style jacuzzi hot tub which I am installing in my back yard. It came with a working pump but no heater. I am having it installed under a tiled roof, and I was thinking the best way to heat it would be with one (or two???) stainless steel cylinder type solar water heaters. They could sit on the tiled roof directly above the tub. My question is... I work as a real estate broker... yet I have never seen this application. Is there a reason that noone does this? Can it be done? If it can be done... are there any local examples and or references I can buy the water heaters from and have them installed?
I would like this project to be a green as possible... and also would like to take advantage of our daily (not lately, lol) sun.
