1 Product summary
1.1 Working principle and applicable areas
Circulating air source heat pump water heater adopts the heat pump principle, consume some
electricity as complement and get the heat through ambient low-grade energy (low-temperature air
energy) through thermal circulation. Transmit the heat to condenser through compressor and then
release high-temperature thermal source for generating hot water. The working principle is same as that
for heat pump air conditioner. The different is that the heat pump air conditioner absorb heat from natural
environment and then supply it to indoor air, while heat pump water heater is using this heat to generate
hot water. Its EER is at least 3 times higher than conventional electric water heater. Heat pump water
heater is a highly efficient, energy saving and environmental friendly product.
This unit is mainly for factory, hotel, restaurant, hospital, beauty parlor, laundry, bath center, large
scale floor heating project and so on.

1.3 Product features
◆
High-efficiency and energy-saving
Adopt heat pump technology, which can transfer the consumed electricity into three times of thermal
energy for heat water, high-efficiency and energy-saving. The operation cost is 1/3 of that for electric
water heater and 1/3 of that for gas water heater.
◆
Safe and reliable
Electricity is only used as the energy for driving medium, while the energy used for heating water is
absorbed from the air by medium. Therefore, the heating method is indeed water and electricity
separation, safe, stable and reliable.
◆
Convenient for installation and convenient for maintenance
The unit can be installed on roof, yard, basement and so on. This unit is with powerful self-diagnosis
function, convenient and easy for maintenance.
◆
All-day operation and wide application range
This heat pump water heater takes sensible heat and latent heat in air as the low-temperature
thermal source, which can provide hot water continuously 24 hours a year and all the year around.
