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.
c. No cross contamination potential, the condenser coil
wrapped around the stainless steel
inner tank
4.2 Max. outlet water Temperature: 60.

2. Operation range
Mode explanation: there are 3 operation MODE: ECONOMY, HYBRID and E-HEATER
ECONOMY MODE: Water firstly is heated by compressor, if can’t get target temp when ambient temp. too low or too high
(limitation figure is shown above), element will start as a secondary heat resource.
Hybird mode: In case of massive hot water consumption, compressor & element will start at the same time.
E-HEATER MODE: Water is only heated by element;
