Heat-Flo, Inc. was started in 1998 as a design, manufacturing, and sales organization. Their initial goal was to develop and manufacture a line of indirect water heaters that delivered the performance features that contractors and end-users required. The two most important benefits of all of Heat-Flo products are quality and ease of installation.

While new models and a commitment to continuous product enhancements were added over the past decade, many of the original key product features are carried through to this day: Large diameter 1-1/8” O.D. smooth coil made of high quality 316 stainless steel; no finned tubing to collect lime and sediment; all connections are on top for a neat, clean installation, durable thermoplastic jacket with 2 inches of soft urethane insulation results in a product that has low stand-by losses, and resists dents and scratches; drain valves and T+P valves are factory installed; L4080B supplied as standard equipment for Single Coil Indirects and Storage Tanks(not Dual Coil or Buffer Tanks).

In 2005, Heat-Flo introduced new products, enhancements, and new product category, solar hot water heaters. When Heat-Flo launched its Dual-Coil units in 2005, these tanks quickly became the standard in the solar market. Heating professionals also found other uses for the second coil that include feeding small hydronic zones or towel warmers, connecting the bottom coil to wood boilers, and connecting both coils to a boiler for double heat transfer.

All connections to all tanks are welded, fully threaded 316 stainless steel nipples. Heat-Flo also offers a line of Hydronic Buffer Tanks. These tanks are used to reduce cycling in hydronic, chillers and heat pump systems and to hydraulically decouple the heat source from the distribution system; this product also does the job of a hydraulic separator with added volume.

Today, all Heat-Flo Indirect Tanks, Dual-Coil Tanks and Storage Tanks come with a factory installed T&P relief valve, and a 1/4 turn drain valve with a brass cap. The Dual-Coil Tanks, Storage Tanks and large size Indirect Tanks (80 and 115 gallon) feature all stainless steel dip tubes to assure long life even in demanding environments. The investments in advanced manufacturing equipment and factory processes such as welding, leak checking, and factory training have paid off. All factory-threaded connections are both Teflon taped and doped, and factory tested. Every Heat-Flo tank undergoes a stringent double leak check and quality inspection to assure the highest quality product gets delivered to the job site. A philosophy of continuous improvement has resulted in Heat-Flo products that are amongst the best in our industry in regards to design, performance, and dependability.
