Ambient -25c Winter Dc Inverter Air Source Heat Pump for heating and cooling home 5KW to 20KW







Sundez DC inverter heat pump is the ideal solution for house heating and hot water so far, with advanced 

DC inverter technology, saving 40% electricity than normal on/off heat pump in practical operation. The whole 

system is optimized with variable fan speed, while the temperature compensation function contributes to a 

more comfortable indoor environment. It can work with solar, boiler or electric heater according to practical 

condition of the heating system.



1.  With Advanced DC inverter technology, it saves 40% energy than normal heat pump in practical operation.

2.  5 modes to manage heating, cooling and hot water, fits your need all year round.

3.  With temperature compensation function, the water setting temperature adjusts automatically as the 

    house's heat loss changes.

4.  Automatically variable fan speed to optimize heating efficiency.

5.  Can work with room thermostat or master controller.

6.  Can work with auxiliary heater.

7.  Split design with water system indoor, preventing water frozen problem.

8.  Fast plug for wire connection between indoor unit and outdoor unit, simplifies installation and avoids mistakes.

9.  With controller interface, plate heat exchanger, circulation pump, flow switch, water pressure gauge in indoor unit.

10. Allows absence of buffer tank.

Quality Control


1. Complying with ISO standard. Quality Ensured. 


2. Complete Inspection for each unit before out of factory, covering water system and electricity detection and testing, ensuring 100% right product before shipment.


3. Strict quality control during production. We have liquid soap detection, halogen detection, electrical detection and water-soaking detection during production to avoid gas leakage and electrical problems .  


4. Full inspection on bigger parts such as compressors, condensers, evaporators, expansion valves, flow switches, controllers etc.. Selection inspection for small parts such as sensors, pressure switches etc.. 


5. Well noise control by using mute cotton for casing plates and soft rubber feet for floating compressors, some of the models use compressor isolation shields.


6. Well insulated with insulated cotton for every pipe and parts, include compressor, dryer filter and each pipes.


7. We have passed TUV  and SGS inspections. We have CE, RoHs, IEC, CCC, CB certificates for most of our products. Some of our products have en14511 test, en14825 test.
