Heat exchangers
Heat meter.
The Resonor primary network (carrying water at a pressure of 20 bars and a temperature of 180°C) interfaces with the secondary subscriber network (carrying water at a pressure of 5 bars and a temperature of 90°C) via substations.
The primary and secondary networks have independent piping. Heat is transferred to the secondary network by means of heat exchangers at the substations.
