I like your design on a solar storage tank conversion using an electric tank, this makes alot of sense and seems like it will save us at least a $1000 versus buying a specific “solar pre-heat” tank. I live in Texas, do I need to use a heat exchanger? It almost never freezes here.
Thanks
No you don’t have to use a heat exchanger if it does not freeze very hard. Our DeltaSol controllers have built in Freeze protection meaning it can cycle if it gets below a set temperature reducing the possibility of the solar loop freezing up.
