Expansion tank
It is connected via a pipe with a threaded connection close to the air separator. For the 24kW version, it is
above the boiler and for the 30kW version, it is in front of the boiler, inside the frame. The expansion tank
contains a diaphragm in contact, on one side, with the system water and, on the other side, with the air under
pressure (pre-loaded to 1 bar) inside the tank. By the expansion of the diaphragm and ensuing compression
of the air, the tank compensates for the thermal expansion of the water in the heating system.
30kW 10-litre version
24kW 6-litre version
Exchanger
The exchanger is a copper laminar assembly. It comprises a thickly finned portion and four circular pipes
connected together in series. The water exchanges directly with the combustion gases and makes the system
safe via a safety thermostat set to 100°C and the limit thermostat (88°C) located in the exchanger. Due to its
shape and design, the heat gets evenly distributed over all the finning, with consequent benefits in terms of
exchange efficiency and the life of the exchanger. A special surface treatment protects the exchanger against
oxidation and corrosion.
