● Working of All-In-One Thermodynamic Heat pump 1. The refrigerant coil R134a gas circulates through the thermodynamic panel where energy is absorbed from the ambient temperature transforming the liquid into a gas and carrying the heat back to the thermodynamic unit. The gas compressed within the system which increases the pressure and therefore also the temperature. 2. Simultaneously a water pump pushes water from built in water tank into the thermodynamic blocks heat exchanger after which the hotter water returns to DHW cylinder. This flow continues until domestic hot water temperature reaches 55°C. Once this is achieved the system goes into standby. 3. Built in sanitary hot water storage tank flled with water is used as hot water source for domestic use. Maximal effciency and low maintenance costs are achieved with state of art system. ● Product advantages 1. WIFI remote control Under wifl signal, you could remote control the heat pump by phones, computers or ipads for adjusting the parameters. 2. Optional Solar heater copper coil Combine With solar water heater system，less power consumption. ● Wide Application
