The answer is yes, your car heater does use fuel to operate. But it recycles heat which is already being used to power the car from the engine, so the extra fuel used by the heaters won't be an excessive amount.The moment the coolant system gets heated, the car’s heater uses it in its favour. Talking on “ does car heater use gas,” one should know that engine runs on gas, so yes, car heater uses gas.
Does a car heater use fuel?
To put it simply, your car heater does actually use some fuel. However, the heater utilises excess heat formed during engine operation, so the amount used is negligible. When the internal combustion engine is running, the heater in your vehicle obtains heat from the car cooling system.
How does the heating work in a car engine?
The Heating Mechanism The moment the engine starts up, heat is generated. The cooling system in the car gets its heat when the engine gains its momentum. Have you noticed that when you start your engine, it takes about several minutes for the heater to give away heat?
How do cars heat up without using petrol?
The fan that makes the heat pass inside the car uses electricity from the battery. And to charge the battery, it also uses some petrol, but very little. “By taking advantage of the heat dissipation from the engine, heating a car is practically free.”
How does a water heater affect a car's fuel consumption?
The cooling of the water in the heater must change the temperature of the engine's coolant. The engine's efficiency must vary with temperature. Therefore, even before the elctrical power which drives the fan is considered, the heater affects the engine's efficiency, and hence, fuel consumption.
