i need a diagram or something . I have a ds160 wood stove that I'm switching to for the upcoming winter. I need a specific diagram that will work to hook up domestic hot water. I currently have 1-50 gal tank but am going to use 2 (I hear that is better)? 1 will have elect to use during summer time. The other will basically just be storage. I'm concerned the water will become to hot if we're using it with 1 tank. I plan on elevating the tanks so I do not need a pump to circulate . The tanks will set right behind the stove. I have a plumber friend but he has never hooked up this system before so I need a good working plan. Thanks in advance.
