How an Eberspächer HYDRONIC water heater works
As soon as the heater receives its starting pulse, the following processes are triggered by the central control unit:
- Automatic safety check.
- The glow plug is warmed up
- The metering pump conveys fuel
- The burner motor starts smoothly
- The fan delivers combustion air
- Fuel-air mixture ignites (flame formation)
- The hot combustion gases flow through the heat exchanger that delivers the heat to the coolant system of the vehicle's engine.
- The heater is controlled electronically and works - according to heat requirement - in several power stages
