18.6Kw Air source heat pump with Copeland compressor for heating/cooling
Domestic series (with Built-in Water Pump) : This series of Domestic Air/Water Heat Pump adopts high efficiency tube-in shell heat exchanger and built in water pump inside the heat pump unit, which ensures not only high efficiency performance of the system but also easy installation work. Different from other ordinary Domestic Split System in installation, just simply connection the heat pump unit to the water tank through water piping, refrigerant pipe connection work is not needed. The water tank connection with this heat pump does not have copper coil heat exchanger inside, which saves the cost of water tank.
