Indirect Coil Solar Water Heating Tank
Stainless Steel (Duplex 2205)

An indirect coil water heater tank heats water using an external heat source such as solar, a boiler, an air to water heat pump, etc. Hot water or a glycol/water mix is pumped through the coil, the heat from the coil heats the water in the tank. There is an electric backup element option for times when the heat source is unavailable or not able to keep up.

The Chiltrix DW80 leads the industry in design & material selection (2205 Duplex Stainless Steel) with a high performance (fast heating) coil, and more.

DHW80 Specifications Sheet

The Chiltrix DHW80 indirect coil water tank uses Duplex 2205 stainless steel for the wet-contact components such as inner tank and coil. Duplex 2205 is much stronger than normal stainless steel generally used in tanks such as 316L And, the 2205 has higher K-Value, for better coil thermal transfer.

Further, 2205 Duplex stainless has more than double the corrosion resistance of standard 316L stainless, meaning the tank and coil will stand up to water problems for a far longer period of time.

Chiltrix DHW80 was designed to be the longest lasting and highest efficiency indirect tank on the market.
