Our 100,000 BTU/hour space heat exchanger is designed for a 20˚F ∆T.  Made with corrugated stainless steel tubing, these exchangers are highly efficient and built to last!  Just as with all our heat exchangers, the space heat exchanger simply hangs on the side of the tank with no in-tank plumbing necessary.
