Overview

Reduces the Impact of Heat Emissions on the Environment

When the air conditioning unit is cooling indoors in summer, it will discharge a large amount of waste heat outdoors. The Withair’s heat pump three in one unit can recover these waste heat and release them into the water to produce sanitary hot water for bathing or kitchen use. The hot water is obtained free of charge, which not only saves energy, but also reduces the impact of outdoor heat emissions on the environment.
Energy Efficiency

Withair® heat pump three in one unit can provide indoor heating and domestic hot water at the same time in winter, also produce hot water independently, so Withair’s heat pump three in one unit is not only a heat recovery central air conditioning unit, but also a heat pump water heater with high efficiency, energy saving, low carbon, environmental protection and safety.
Quiet Operations

Unique designs, including inverter-driven compressors and natural convection heat distribution, ensure quiet operation of Withair® indoor and outdoor units.
Wide Selection

Withair® heat pump three in one unit is widely used in hotels, schools, hospitals, bathhouses, dormitories, nursing homes, barber shops, restaurants, villas and so on
