A few years ago I remember a big deal being made about BMW's new heater system that retains heat for a number of hrs for quicker cabin warm-up in cold climes. IIRC it had some sort of ceramic insulation material that was ultra effective at holding the heat for a long time.
Does anybody have any experience with this? Is it any good? Has it been used on other vehicles?

I like cars, and technology, but sometimes it gets out of hand. Just use a plain old heater core, so it doesn't cost $2,000 for a replacement. Gimmicks like that strike me as a fine idea until it fails, and now you've got an expensive, complex system to repair instead of a plain one.

I use anti-ecodriving when starting the car cold. That means, I use the first and second gear all the time until the car is warm and nice. To low gear = lots of friction heat into the engine cooling water. Takes maximum 2 minutes until I have lots of nice heat from my 65 hp engine.

about 'not letting cars warm up', well, that is fine and dandy when it is warm but when you start the car and the temp gauge says -32C when you get in in the morning, i think its best to let it run for a few minutes.

For quite some time, BMWs have had a "REST" button = residual heat, where it just blows air over the heater core dumping...residual heat...into your car. It may seem like a gimmick feature, but if you're just running into the mall for an hour or something, it's great. Keep in mind that most BMWs have a gigantic battery (in the trunk, opposite side of the driver, to counteract his/her weight since most of the time, it's only the driver in a car), so draining it isn't really an issue.
The newer ones have a "normal" heater core style heater, but some (mine is an '07 7 series, not sure about the rest) have a regular electric heater as well. Since the 7 has a V8 engine, it takes some time to warm up, so it's great having hot air right away. I think most portable heaters may be referred to as "ceramic heaters..." not sure on that though, but seeing as how the system is basically a portable heater stuffed into your HVAC system, that'd be what you're talking about.
