Solar water heating tanks or other indirect tanks with coil heat exchangers can be used for domestic water heating with Chiltrix air to water heat pumps if they have a proper design. Chiltrix also offers a totally unique ultra-high performance stainless indirect tanks designed specifically for air to water heat pumps, the DHW105, DHW80. The DHW40 is available as a stand-alone indirect tank and is not part of an official water heating package at this time.

The Chiltrix line of 2205 Duplex stainless inner tank offers the highest corrosion resistance of any available stainless steel tank material. The Chiltrix DHW80 tanks (75 gallons net of coil) and DHW40 (36 gallons net of coil) are designed to outperform every indirect heat exchanger tank or solar tank on the market, with .43 ft^2 per gallon of coil surface area, the fastest heat transfer, and truly exceptional durability. The DHW 40/80 tanks convoluted coil also disrupts laminar flow for a further increase in thermal performance.

^NOTE 1 generally, the DHW40 tank is for an ADU or tiny house, 1-2 occupants. Tank size is not linear to apparent capacity, meaning, for example, reducing tank size by 50% reduces the number of supported occupants by more than 50%,
*NOTE 2 DHW40 is not compatible with CX50. This tank is best used with the smaller sized CX units.
