As Toledo Jim says, diesel engines generate less waste heat, especially the reasonably modern ones.

I have a turbodiesel panel van from 2007 (so not particularly new) and live in a cold climate, it actually has a supplementary a supplementary diesel-burning heater that kicks on automatically to warm the coolant enough to provide cabin heat. With temps around freezing this doesn't kick in and it can take the engine 10 mins of driving to hit 80c / 180F. On a cold day at say -20c / -4F the extra heater is whining and whooshing away otherwise the engine would be very unhappy indeed.
