Good point!
I don't have it up and running yet but I bought a lister 8/1 clone last summer that could charge/power the batteries at night. They run off of any fuel oil. Im hoping to run it on used veggie oil, or...keep it just for back up to save on engine wear and go with a thermal store. I already have 3 indirect water heaters I have found cheap on local adds. I have an 104 Gallon Marathon plastic, 80 gallon IBC stainless, and a 50 gallon stainless(forget the brand).
I have not done the math yet on BTU needs/storage so they may be to small for over night. Do you know what size tank an average house would need for over night storage? Are we talking thousands of gallons?
I like the idea of over night storage. Thanks
