The Westinghouse WI080 80 gallon stainless steel indirect water heater is a culmination of over 25 years of indirect system manufacturing experience. Built using high quality 316L stainless steel materials, the tank and heat exchanger eliminate the need for anode rods, resist corrosion, and allow for the system to be virtually maintenance free. The corrugated heat exchanger draws energy from a boiler to heat the domestic hot water with an extremely low pressure drop. The built in auxiliary port for recirculation increases overall efficiency by eliminating short cycling of the connected boiler. The stainless steel indirect water heater generates over 80% more hot water than many water heaters of similar size and offers extreme savings.

What is an indirect water heater? An indirect is a storage tank with a heating coil built inside the tank. Hot water from any hydronic heating boiler is circulated through the coil inside to heat all the water in the tank. The unit is piped like any other heating zone.
