Air to Water heat pumps for Hot Water (D Series: Direct Heating)
D series of Domestic Hot Water Heat Pump adopts advanced variable flow rate control technology, keeping a constant water temperature in the cold climate and hot climate. Unlike cycle heating heat pump, the outlet water temperature from direct heating heat pump directly reaches the setting temperature. Therefore it’s much faster than cycle heating models to produce hot water. The fast de-frosting technology enables the system work well in the low temperature, moist ambient conditions.
It adopts high efficiency tube-in-tube water heat exchanger and incorporates a built in German Wilo pump for easy installation work. The unit is capable of producing hot water with a maximum temperature up to 60°C. It can be retrofitted to existing geyser to replace electric water heater, saving more than 2/3 energy.
