I'm just a little sick of the bus being freezing cold in the middle of winter, and having nothing to warm the passengers up with. Can't say it does anything good for customer relations.

What do you do for the heating cycle?

If so, then the heating cycle wouldn't be reliant on coolant from the engine for heating? ie no long pipes from the rear mounted radiator to the air conditioning unit.
On the newer Transperth buses on cold days when the air conditioning is generating warm air, it seems to come out of the same ducts as cold air on warm days, - suggesting to me the system for cooling the passenger saloon is reverse cycle. Maybe the windscreen demisters still rely on heat from the engine as per the 0305s which have a coil below th ewindscreen and pipes running from the engine carrying the warm coolant?
