Automatic Heating
As soon as water temperatrue for shower drops to the setpoint, the heat pump starts working so as to ensure constant shower.
Short Heating Time
Hot water can be supplied in a short time within 1hr as the inlet water temperature is greatly higher than that of tap water.
Extended Shower Time
With sufficient hot water supply and fast heating technology, the heat pump covers the hot water requirement of a whole family.
Easy & Clear Control
The clear controller display, specially designed by VKIN, makes it easy for users to power on/off, set temperature, timer and heating/defrosting mode. Available in hybrid/heat pump Only/Electric Only/Powerful/Vacation pre-set operation modes for easy control.
Compressor Overload protection
When the compressor is working overload, the unit will stop working to protect the whole system.
Heat pump provides up to 60℃ hot water for you constantly by circulating heating. It’s specially designed for the residential demand. With the features of stable hot water supply and high energy efficiency, it’s a perfect choice for domestic hot water.
The Heat Pump Water Heater can produce as high as 60℃ outlet water. While in the market, most of the domestic water heaters make only 55℃. The 60℃ high outlet temperature enables the water volume for use to increase by 30%.
Continued excellent performance at low-ambient outdoor temperatures through use of DC Inverter technology.
When water inlet volume is low, the unit stops to protect the system. When the water volume recovers, the unit starts working again.
When the unit is standby and water inlet temp. is lower than 4oC but higher than 2oC, the water pump starts up to protect the system.
High/Low pressure switches will switch off the heat pump automatically to protect the whole system when the pressure is over high/low.
When the compressor discharging temp. is higher than 110oC, the unit will not work until the temperature is lower than 85oC.
System power supply connections at indoor tank, for easy installation. Water connections at top of tank for easy installation. Refrigerant lines run from indoor and outdoor unit, just like ductless heat pumps, for easy installation.
