Note that a standard electric water heater has a coefficient of performance (COP) of 1.0, meaning that it is 100% efficient. 1 kW of electrical input gives 1 kW of heat output.  100% efficiency sounds good, but not really. Depending on ambient temperature, a heat pump such as Chiltrix will have a COP of between 2 and >4 (200% to >400% efficient) depending on ambient temperature. That's why heat pump water heaters are becoming popular.

Adopting the European approach to air to water heat pump system design, the Chiltrix DHW multi-function method allows your heating/cooling system to also perform as a high-efficiency water heater. And the Chiltrix method has higher net efficiency than a typical USA-style self-contained heat pump water heater because the "cooling" side of the Chiltrix water heating system is outdoors and does not rob heat from the indoors during winter. The water heating function can be used with Chiltrix in any supported systen, for example with ductless fan coils, with radiant heating, radiant cooling, ducted air handlers, or with any combination of the above.

Note, neither CX heat pumps or DHW tanks are designed or supported for recirculating DHW systems. In many cases the Chiltrix system can work for recirculating hot water systems but we do not recommend them that way.
