Eberspacher Operation

How do the Hydronic range work?

As soon as the heater receives its start pulse the following procedures are triggered by the central controller;

1. Automatic safety check.
2. Burner motor starts, preliminary ventilation of the combustion chamber
3. Ignition starts and fuel solenoid valve opens
4. Atomiser spays diesel or heating oil EL into the ventilated combustion chamber. This mixture is ignited by a high tension spark to produce a flame.
5. The hot combustion gases flow through the heat exchanger, which transfers the heat to the engine's water cooling system.
6. This thermal energy is forwarded to the passenger compartment via the vehicles own water/air exchanger. The residual warmth continues on to the engine.
7. The heater is electronically controlled and works intermittently. In other words, the burner comes on for different lengths of time depending on the heat required.
