Ok Here is the question. I have my homemade 575 gallon thermal storage online. I think I worked out all the bugs to make everthing work together. So my question, my wood boiler is running, there is no call for heat so all heat is going into storage unit. My storage unit is at 180 and my wood boiler circulator is still on, but the fire is almost out. So my thinking is it is circulating the water in the storage unit and will never shut off? My aquastat on my boiler is set on 170 with a 10 degree diff. Right? Wrong?
