Heat-Flo 80 gallon stainless steel single coil indirect tank

Heat-flo’s high efficiency indirect water heaters are made with quality stainless steel materials that provide excellent heat transfer and a longer tank life, as well as abundant hot water and low operating costs. Indirect water heaters work in conjunction with a boiler to heat the water that's circulated through the heat exchanger in the tank.

When paired with an high efficiency boiler, Heat-flo’s indirect water heaters can generate over 50% more hot water than many water heaters of similar size.
