Booster heat pump: when to use for DHW or temperature boosting

A booster heat pump is used when a low or medium temperature source already exists, but a higher final setpoint is required.

Example

It can take water from a low-temperature network and raise it to a temperature suitable for DHW.

Advantage

It allows the main heat pump to operate efficiently at a lower temperature, while the booster covers only the final temperature lift.

Applications

Hotels, apartment buildings, and facilities with high DHW demands.
