Operation
Based on the thermodynamic water-ammonia absorption cycle
(H
2
0–NH
3
), the appliance produces hot water using outdoor air
as a renewable energy source (cold source) and natural gas (or
LPG) as primary energy.
The thermodynamic cycle takes place within a hermetically
sealed circuit, in welded construction, perfectly tight, factory-
tested, which does not require any maintenance or coolant
top-ups.
