Heat Exchanger

The copper heat exchanger has different size and number of fins according to the appliance model (12, 16
and 20l/min)and also different copper pipe connections if in high output range (16, 20, 26 l/min). This
configuration ensures the sealed heat transfer from the flame heat to the water that flows through the copper
pipes.
