3 FUNCTION
Function Description
High efficiency and energy saving
The energy consumption is one fourth of electric water heater and one
third of gas water heater of the same capacity.
Safe and Reliable
Electric energy drives refrigerant in air source heat pump water heater.
The refrigerant absorbs heat energy from air which is used for heating
water, so the water-electricity isolation is completely realized. Potential
fault like electric leakage, gas poisoning, explosion and dry
combustion for gas water heater will never happen on air source heat
pump water heater. It is safer and more reliable than the conventional
water heater.
Easy Installation and Maintenance
The unit can be installed on balcony, rooftop, yard, basement and so
on, no special machine room needed. It can be installed in any place
without direct sunlight. Intelligent self-diagnose system is provided for
easy maintenance.
All-day Operation and Wide Application
Heat pump water heater makes use of sensible heat and hidden heat in
the air as low-temperature heat source, so it can continuously supply
hot water all day, no matter in which season or what the weather is like.
It is designed to work at wide ambient temperature range from -7 to
43 .
Intelligent Control
Microchip control, easy operation interface, and various kinds of
history operation data can be tracked.
Multi-modular network can control up to 16 host units; parameters of
each unit can be freely set
Daily timer on/off function and complete safety ensure reliable
operation.
