I presume you use the heater in winter, Louis...
ONQ.
I seem to remember reading that the diesel mix is different in Winter to cater for freezing temps....
- You use your heated seats [assuming you have them] which are electric and separate from the aircon system.
No, less friction. Hot tyres, hot road surface = more friction, more grip and higher fuel consumption.... The only possible reason I can think of is that somehow there is more friction when the road is colder...
Lots.... But I'm sure there are other reasons...
Some cars use electric heaters in the passenger cabin, most use a heater matrix (additional radiator) plumbed into the cars cooling system and some expensive cars use both with the plumbing taking over from the electricity once the engine reaches operating temperature....
- Even if the heat is from the engine, its not direct, its probably via a heat exchanger and I expect that is a pumped system also - more electricity....
AFAIK, these were first invented to prevent the cylinder heat splitting due to the extreme cold of winter in these countries, where the temperature drops below the usable range of the anti-freeze in the car cooling system.<snip>
Are there possible solutions to the problem?
- Engine pre-heaters powered from the mains that plug into and heat the engine block, coolant and oil before you start the engine, used extensively in Scandanavia, Canada and the US. Think of them as "super" glow-plugs that are fitted to diesels anyway
Ah sure just leave the car there and pull the bike out from the boot and off ye go...
- Block off the radiator fins with card-board until the engine heats up (old lorry driver's trick that might not do your warranty any good) and then hop out in the middle of the M50 to remove the card-board

Well worth 0.5l/100km...I can't imagine life without them now
