How much fuel is consumed by idling with the heater on for one hour?
1 Answers
Idling with the heater on for one hour consumes approximately 0.6-1L of fuel. Under normal circumstances, using the heater does not increase engine fuel consumption. The heater relies on the engine's heat dissipation system, where a small fan in the engine compartment blows the heat collected by the cooling system into the car. How to use the heater When the coolant temperature gauge reaches the middle position, you can start using the heater. However, it is recommended to first use the external air circulation mode to expel the cold air inside the car, then switch to internal air circulation after 3-5 minutes. Hazards of idling with the heater on: Since the engine is idling, incomplete fuel combustion may produce carbon monoxide. If the windows are closed, the concentration of carbon monoxide inside the car will gradually increase, potentially leading to carbon monoxide poisoning for the occupants. Additionally, this can increase engine carbon buildup.
