The hot water for the heating system and for the domestic circuit is produced by a primary circuit
and a secondary (domestic) circuit that are activated according to demand.
PRIMARY CIRCUIT (BOILER CIRCUIT)
The primary circuit with the relative control and safety devices is activated with each heating or
domestic circuit demand for water.
- OPERATION
The copper blades of the water-gas exchanger (10) absorb the heat contained in the flue gas
produced by combustion.
Those blades then transfer the heat to the water being circulated inside by the boiler pump (7).
The water is introduced directly into the plant or can be deviated inside the cylinder coil (3).
This depends on the position of the electric 3-way valve (23) which, depending on the demand,
allows water to flow through the plant delivery (M) and return (R) pipes or deviates it to the coil (3).
