Our household heat pump water heater adopts high efficiency tube and shell heat exchanger and has built in water pump inside the heat pump unit. This ensures not only high efficiency performance of the system but also easy installation of work. This product is different from other ordinary domestic Split System which is simply installed to connect to the heat pump unit and then to the water tank through water piping. The refrigerant pipe connection work will not be necessary to heat the water. The water tank connection with this heat pump does not have copper coil heat exchanger inside, which saves the cost of water tank.

As a manufacturer and supplier specialized in household heat pump water heater in China, We also provides commercial air source heat pump, split air source heat pump, solar water heater, among others.
