Technical documentation
The hot water for heating and home use is produced thanks to two separate circuits, selected
according to need.
The central heating circuit, with relevant control and safety devices, is operated every time a
central heating request is made.
- OPERATION
The heat contained in the gases produced by combustion is absorbed by the copper blades of the
water-gas exchanger (7) which, in turn, transfers this to the water circulating inside thanks to the
boiler pump (17).
The hot water is then transferred directly into the central heating system through the supply pipes
(M) and return pipes (R).
