9. What temperature range can Hien heat pumps operate in?
The operating temperature depends on the specific model.
Hien’s R290 product materials identify stable operation at low ambient temperatures, with some product materials highlighting operation at approximately -20°C. Specific models and configurations should be evaluated against the required climate and water temperature.
For projects in colder regions, buyers should evaluate:
Minimum ambient operating temperature
Heating capacity at low ambient temperature
COP/SCOP at the target climate
Maximum water outlet temperature
Defrost performance
Backup heating requirements
This information is more useful for product selection than relying only on a nominal heating capacity.

Outdoor design temperature
Indoor target temperature
Heat distribution system
Hot water requirement
For domestic or commercial hot water, calculate:
Number of users
Daily water consumption
Required water temperature
Peak hot-water demand
Cooling requirement
For heating and cooling applications, determine:
Cooling load
Required chilled-water temperature
Indoor terminal equipment
Operating schedule
Industrial requirement
Industrial buyers should additionally specify:
Required process temperature
Heating capacity
Process flow rate
Operating hours
Existing heating system
Required return temperature
The final model should therefore be selected based on engineering requirements rather than simply comparing the nominal kW rating.
