Heat-Flo Indirect Water Heaters and Buffer Tanks
A.J. LeBlanc Heating installs Heat-Flo indirect water heaters, high-output stainless tanks, and hydronic buffer tanks across Southern NH. Pairing a Heat-Flo indirect with your existing boiler is one of the most efficient ways to make domestic hot water for a NH home.
Heat-Flo Indirect Water Heaters
Heat-Flo, LLC designs and manufactures high-quality indirect water heaters and hydronic storage tanks for residential and light-commercial use. Their indirect water heaters use heat from your existing gas or oil boiler to make domestic hot water, which is typically more efficient than running a standalone water heater alongside a heating boiler. Heat-Flo's stainless steel high-output models are well suited to NH homes with high hot-water demand.
