Is it normal for the car's heater to only get hot when set to H1?

[StAmara]

It is normal for the car's heater to only get hot when set to H1. Using the heater does not consume fuel: The reason the heater does not consume fuel is that it transfers the heat generated by the engine into the car. Even if the heater is not turned on, the engine still produces heat, which would otherwise be expelled outside the car. Therefore, using the heater has no impact on fuel consumption. Precautions when using the heater: Since the heat from the heater comes from the engine, prolonged use can produce toxic gases like carbon monoxide, which can be dangerous for passengers. If you notice any unusual air quality inside the car, immediately open the windows or doors to ventilate and expel the toxic gases. Additionally, the heater can also be used to remove frost or fog from the car windows.
