All domestic hot water heat exchangers are engineered for a 3.5 gpm flow rate and include an anti-scald valve.  Made with smooth copper tubing and manifolds, these exchangers are sturdy and built to last!  Just as with all our heat exchangers, the domestic hot water heat exchanger simply hangs on the side of the tank with no in-tank plumbing necessary.

3psi @ 3.5gpm will deliver 96k BTU/hour
