Isotemp Water Heater Basic 40 TCT (Dual Coil)

The Basic 40 and Basic 75 are the only two models that have the double engine heat exchanger option.  The double coil is sometimes used by boaters who have hydronic heating to maximize use of the heating.  They are often used in conjunction with two engines such as a main engine and a generator to take advantage of the surplus heat provided by two separate sources.
