DC inverter heat pump with EN14825 certificate-A++ energy class




COP 5.97 for 9KW DC¬†Inverter¬†air source¬†Heat Pump with Heating and Cooling and domestic hot water¬†functions, with R410a refrigerant and¬†most advance European technology to work well in Minus -20¬ļC

Much more Higer efficiency than normal air source heat pump.


Palm EN14825 test certificate issued by Intertek lab. A++ energy class inverter air to water heat pump.

Palm EN14825 certificate

Main Features:

1. Much more higher COP than normal DC inverter heat pump
2.  Installation is easy and flexible..
3.  Can be connected with solar water heater system.
4.  All water access parts are stainless steel or copper to keep safe, healthy and non-pollution

5.Secondary heat source auto switching function enable Palm AEO to heat together with the existing or second heating system.  Inner thermostat to Swift automatically between 2 heat sources base on the target outdoor temperature preset by the user.

6.Seasonal auto switching function to separate Winter heating  and Summer cooling circulation water for comfortable and more energy saving.


7. Weather Compensation Function, Auto target water temp curve according to different  ambient  temp.
