Robert, I replaced mine with a whale(seaward) S1100, 11 gal, galvanized steel. It comes in either front or rear heat exchanger configurations, and has the electric hookup as well. I added rigid insulation to the outside of the case; water stays hot or at least warm for a long time. Available at the Binnacle, which, I think, is close to where you are Robert.
