I plan to use that and the turbine to preheat water in a large tank in the basement.What you could do is buy another tank(water heater) or find one and circulate your water through it by removing both elements or the supply and feed.It would serve has preheater to your existing heater.Those pumps don't draw much more than a 100w bulb.
Anyhoo very nice work and hope your snow leaves soon.Ahhh a hot tub dump load courtesy of your girlfreind.I like that heater core and muffin fan idea. Just thoughts
