    The type of work I do can mean sitting idling for a long time in situations where you would want the heater running. All the stop starts I have had had had a button to disable it although these are mostly VAG cars

    Doesnt matter. The car will restart when it cant keep the heater at the setting you have it at anyway.

    What? The heater runs of the engine heat and wont circulate without the engine running.
  • My kia proceed EcoDynamic has stop start tech, it has a button to deactivate it permenantly just to the right of the drivers side dash with the light adjustment and cabin light adjustments are. It wont come on with the demisters are (when activated) or when the aircon used climate control is on. it wont come on when the vehicle is regenerating DPF, and it wont come on when the vehicles engine is not upto temp.

    Latent heat in the water system.

    Once the car drops below a cabin temperature the car will restart.

    Heat retained by passing an air flow over the coolant?:rotfl: the heater doesnt work when the engines off;)

    *sigh*

    The car is at a certain temperature with the heater on, right?

    With the engine off in stop / start mode the fans will continue to run.

    Once the car can no longer sustain that temperature when the car has switched off due to stop / start, it will restart the car.

    That may take a minute, it might take 10 minutes. There will of course be hot water in the water system - you do know it doesnt cool down instantly, dont you? So it will use what latent heat remains in the cooling system in the mean time.

    You'd have been one of those people who laughed when it was first suggested the world was round wouldnt you?

    Stop start won't work in an iq if the windscreen demister button is on, even if fan isn't on. The off button is a temporary off function, next journey it will be on by default.


    Aircon will switch off when stopped.


    Over 5 years / 36k miles, stop start has turned the engine off for 28 hours 20odd minutes as pf this afternoon, so a fair bit of petrol saved and fewer squirrels killed to death.

    Little light hearted thoughts....

    How much extra fuel have you used carrying the extra weight of the stop start system :)

    Answer 1 = Not as much as carrying my sandwich box?

    Answer 2 = More than a Big Mac meal?

    Answer 3 = More than its saving :)

    The heater wont work like that, it would be stupid to think it would. Your not smart enough for me to talk to any more
