HIEN’s product portfolio includes R32 air-to-water heat pumps and commercial heat pump products.

3.3 Residential Heating and Cooling Heat Pumps

Residential heat pumps can provide space heating and, where supported by the selected model, cooling.

These systems may be suitable for houses, apartments, and other residential buildings using compatible hydronic heating or cooling systems.

When selecting a residential heat pump, buyers should consider the building’s heat loss, local winter design temperature, required supply-water temperature, and domestic hot water demand.

HIEN offers residential heating and cooling heat pump products for different application requirements.

3.4 Commercial Heat Pumps and Heat Pump Water Heaters
