It features a built-to-last, robust tank and is available in 65- and 73-gal. tank sizes with inputs ranging from 125,000 Btu to 300,000 Btu. The featured multi-flue design increases heat transfer resulting in greater transfer of energy to the water. A low-profile design and front and rear inlet/outlet water connections ensure installation flexibility as a replacement unit or a new installation. These units can be installed as a single unit or as part of a multiple-unit installation for greater capacities.
