I just got back from a Trade Show, and there was one company that was attempting to sell Vacuated Tubes for both Solar Heating of a pool, and Solar Heating of Domestic Hot Water.
Being the skeptic that I am, I am wondering if there is anyone out there who has such a system, or even has a system that just does their Domestic Hot Water. Are you happy with it, are you saving over 50% of your hot water usage? Can this system also be plumbed to use the excess hot water in the summer for your pool, rather then just plain dumping it?
Look forward to seeing some replies, being an ower of a Hybrid I am always looking at ways to save and help the environment at the same time.
