2.2 Hydraulic circuit – tap water
Hydraulic diagram for tap water
When the card receives a signal from the flow meter indicating a tap-water draw of over 2.5 l/min, the
boiler starts working normally for tap water. If heating was in operation, or the pump was anyhow working,
the boiler will in any case give priority to the tap water, stopping the pump. The tap water does not
exchange directly with the products of combustion, but via the heating water in the exchanger, avoiding
sudden changes in temperature.
