Ahah!!! We were right, he does think it's an electric heating element!:rotfl: (Just kidding TD
)
Anyway, my analogy wasn't looking at thermostats or anything any more complicated that a heat source (boiler/engine) and the heating element (radiator/heater matrix). The heat source is on, the heating element is hot. The heat source gets turned off, the heating element stays hot because of the hot water inside it. How difficult is it to understand?
Try a kettle. You turn it on, it gets hot. You turn it off, it stays hot. As many people have said, it is latent heat. The heater doesn't instantly go cold because the water in it is still hot.
That was what the OP was asking before you confused matters. If they have the heater on, will it stay hot when the stop/start turns off the engine? No thermostats, no turning it on after the engine has turned off, it is already on and hot.
The heater matrix in this case is hot because of the engine coolant being pumped through it while the engine is running. After the stop start activates and turns the engine off, the water in the heater element stays hot and slowly transfers it's heat to the cold air being drawn in by the fans.
Once the heater element has cooled down (depending on the size of the heating element and the volume of air flowing over it) the engine starts again and hot water from the rest of the engine passes through the heater element and it gets hot again. This cooling cycle can take between 2 and 5 minutes, it is not instant.
There, hope that helps you understand how a car heater works.

So, do you agree with the description or not?
