• The burner motor starts, the combustion space in pre-ventilated, the glow plug is warmed up, the metering pump conveys fuel.
• The glow plug ignites the fuel-air mixture, the flame is formed.
• The hot combustion gases flow through the heat exchanger.
• The hot air fan draws in room air or fresh air.
• The heat of the combustion gases is transferred by the heat exchanger to this hot air.
   

How the Hydronic coolant heater works: 

• Automatic safety check.
• The glow plug is warmed up.
• The metering pump conveys fuel.
