4. Features
4.1 Safety
a. Complete isolation between water and electricity. No electric shock problem, more safety.
b. No fuel tubes and storage, no potential danger from oil leakage, fire, explosion etc.
4.2 Easy operation
The system can be controlled simply through the wired controller.
4.3 Automatic control:
Automatic start-up and shutdown, automatic defrosting. Save you much extra operation.
4.4 Rapid speed to produce hot water.
4.5 High efficiency and energy saving.
The unit adopts heat pump principle, which absorbs heat from outdoor air and produce heat water, thermal
efficiency can be approximately 4.9.
4.6 All-the-weather running.
Within the temperature range from -15℃to 43℃, it will not be affected by night, overcast sky, rain and
snow.
4.7 Modular design, maximum connection 16sets basic unit
