To reduce carbon emissions to the environment and curb global warming, an R290 Full DC Inverter Heat Pump has been developed. Compared to R410A refrigerant with a GWP of 2100 and R32 with a GWP of 675, R290 has a GWP of less than 20 and is recognized by the industry as the most development potential and eco-friendly refrigerant.
The perfect performance can meet user's needs of house heating, cooling and domestic hot water throughout the year (by 3-way valve):


Under low ambient temperature, the performance of normal heat pumps is limited. This unit can operate stably and efficiently in extremely cold regions of -25ºC, maintaining high COP and outputting 75ºC hot water.

The Full DC inverter technology enables the unit to intelligently adjust the operating frequency and control the water temperature. It saves up to 50% energy compared to ON-OFF units and up to 75% compared to traditional boilers.
Core Components: DC Inverter Compressor, Stepless Fan Motor, DC Inverter Water Pump.


Passed the ERP A+++ energy class test. Energy efficiency grade reaches A+++ at both 35°C and 55°C. The SCOP can be as high as 4.86, ensuring ultra-high efficiency.


The IoT cloud management platform connects with Wi-Fi or DUT for remote monitoring. It records all operating parameters and provides real-time error reports for quick solutions.
