Heating system configurations

The split air to water heat pump is designed to work in mono-energetic or bi-valent heating systems. It provides efficient 

control and reduces energy use while maintaining comfort in the building.

The functionality of the split air to water heat pump depends on the installed components and the selected configuration 
and it can be configured and upgraded to meet many application requirements.

11.1.1 

System configuration

 

 



Mono-valent system

The split air to water heat pump is sized to provide 100% of the heating requirements on the coldest day the year.

 

 



Mono-energy system

The split air to water heat pump is sized to provide 80% of the heating requirements on the coldest day of the year. An 
auxiliary heater (inside the unit) is used to provide the additional heating required on cold days.
