We currently offer two different sized space heat exchangers: 100,000 BTU/hour and 150,000 BTU/hour.  These heat exchangers are designed for a 20˚F ∆T.  1 1/4” manifolds allow maximum flow for heat input into tank and removal.  Made with smooth copper tubing and manifolds, 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.
