Heat-flo Indirect Water Heaters


Energy Saving Stainless Steel Indirect Water Heater

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.

Quality Design and Construction
  • CTanks and coils are all stainless steel construction.
  • Large, smooth-wall coils deliver full output for years - no finned tubing to collect lime and sediment.
  • Over 2" of insulation, providing less than 1° / hr. heat loss.
Easy Installation
  • All connections are on top on the standard units for a neat, quick, and clean installation.
  • Brass drain and relief valves are factory installed.
  • Honeywell L4080B Aquastat control is standard.
Residential and Commercial
  • Models are available in 30, 40, 50, 60, 80, and 115 gallon sizes.
  • Bank together 80 and 115 gallon units for applications with high water heating demands.
