Indirect Water Heaters
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.
No direct flame reduces lime accumulation and there are no electric elements to burn out. The units are all stainless steel construction. If you are installing or updating a hydronic heating system, or have an existing hydronic heating system, the indirect water heater is the right solution every time! Say goodbye forever to hot water shortfalls and high electric water heating costs.
