Size the system correctly to ensure savings. Systems with lower capacity heads or ducted systems are needed for heat pump installations in smaller unit types, such as those in multi-family buildings.
Introduce cooling to improve resident health and comfort. Adding cooling with heat pumps reduces exposure to extreme temperatures, and increases overall resident satisfaction.
Include thermostat logic for heat pump controls. The ability to allow separate temperature limits for each mode helps combat the rebound effect and improves energy savings while still maintaining thermal comfort.
When installing air source DHW heat pumps, consider how the location and configuration of the existing space will impact airflow, thermal comfort, and noise levels of adjacent spaces.
