Heat Pump Features

Air to Water Heat Pump




SPRSUN air source heat pumps are designed for domestic/commercial space heating & cooling in the air conditioner market where lowest air temperature is above -10℃.


 ● Efficient and Energy-saving 

Air to water heat pumps absorb hot energy from the air freely, while the electricity is only used to drive the compressor to pump up the heat from the air, so they consume just a quarter of power of traditional electric water heaters, saving a lot of electric cost for users.  


 ● Green and Environmental Protection

By using air source energy and electric power,there is no harmful gas being discharged during the operattion of heat pumps. R410A refrigerant guarantees fluoride-free emission. 


 ● All-weather Operation

Stable operation without being influenced by windy, rainy or snowy weather. 


 ● Endurable 

Copeland scroll compressor, Danfoss electronic expansion valve, Eaton AC contactor and thermal relay as well as other brand components of the heat pump guarantee high product quality and a long lifespan. All of our screws and clips  (both external and internal) are stainless steel. The cabinet we are using is made of  GALVANIZED STEEL, making the product more rust resistant and durable.


 ● Multiple Protections

For example, if water flow is not enough in the system, the system will show high pressure protection and stop the heat pump automatically to protect the compressor from being damaged. Also, there is high current protection: if the power supply is not stable, the heat pump will show the high current error to stop the heat pump and avoid compressor damage.


 ● Linkage Function

 External signal on/off function


 ● Guaranteed Safety

Complete isolation of water and electricity avoids electric shock, explosion and poisoning. 


 ● Convenient: 

Air to water heat pumps are easy to install. They can be placed in many places, such as garages, balconies, kitchens, etc.
