Air to Water GHP Unit Inputs and Outputs
With internal air-side and water-side heat exchangers the ECWP71J unit provides a source of cooled or heated water from the air source heat pump as well as providing an output of heated water from heat energy reclaimed from the gas engine inside the unit.
Air to Water GHP Unit Operation Modes
The unit is can operated in cooling or heating mode and switch over between operation modes can be done remotely without the need for intervention at the unit.
