1.3 Product Features

1.3.1 General

GREE air to water heat pump is a completely flexible, energy efficient home heating system that
extracts the heat from the outside air, raises this heat to a higher temperature and then distribute
swarmth around the home using under-floor heating, radiators or fan convector heat emitters.

1.3.2 Features


Wide Operation Range
Heating: -22~35°C; Cooling: 10~48°C; Water Heating: -22~45°C.

High-efficiency Component(Inverter pump, Inverter fan, Plate heat exchanger)
1. The A-class high-efficiency inverter water pump which complies with the European Erp directive,
can control the running frequency based on the actual load. Therefore, it can enhance the operation
effcieicy and control the water temperature more accurately.
2. The DC inverter fan can control the air volume accuratately and make the system run more stably
and save more energy.
3. The high-efficiency plate heat exchanger will improve the unit's performance largely at a low price.

All-in-one Design
1. The unit can integrate with terminal units, like the radiator, floor heating device, FCU, water
heating device, solar kit, gas furnace and swimming pool etc. Versatile functions can meet various kinds
of demands from different users and enhance applicability of this product.
2. The all-in-one structure design can save more installation cost, reduce risks of refrigerant leak,
and improve safety and reliability of the system.

Brand-new Controller
1. White appearance, exquisite design, and the wall-mounted design will facilitate installation.
