Er.. No. The heat from the heater matrix is generated by the coolant flowing through it. It's pushed into the cabin by the fans. If the engine isn't warm, you won't get any hot air. If your car is sitting idling for 10 minutes, it won't be nearly as warm as it would if you've been driving it for 10 minutes.
An idling engine doesn't warm up very quickly, so all the wear conditions that are associated with a cold engine are maintained for longer e.g. low oil flow, rich mixtures causing bore wash coupled with larger piston/bore clearances giving increased blowby and oil dilution etc.
Which is what I said. In order to get the car warm quicker, get moving. The heater matrix requires airflow as well as the blower, hence why the blower is almost ineffective at idle and slows down the time the engine takes to warm up.
Get driving, blower off, the engine warms up even quicker again![]()

Your climate control unit shouldn't push any air at all into the cabin until the heater matrix can provide enough heat to heat the air to the required temperature.
If that happens through 10 minutes of idling on the driveway or 3 minutes of driving then so be it, but to say that the cabin heating systems are ineffective solely because the engine is idling is absolute hogwash.

I'd be surprised if anything remotely recent did that. I mean, if whatever kind of heat-exchanger this system used was to fail, the heater would literally be sucking exhaust gasses into the car!

The heater matrix is a radiator, as in water to air, it doesnt require airflow. To provide heat to the cabin the blower does that by drawing air through its core.
Hold on wut?
It doesn't require airflow, yet it provides heat by drawing air through its core. That would be airflow then. A heater matrix also takes natural airflow whilst a car is moving. Hence, older cars will supply heat to the cabin if set to hot regardless of whether the blower is on or not. If you're not moving and your blower is off, there is no airflow. If you're not moving and your blower is on and your engine is cold you are pulling any heat from the engine immediately into the cabin and it will remain cool / warm until the engine properly warms up.

NO car I have ever been in will supply hot air (to any noticeable extent) to the cabin with the blowers turned off. That is the point in them being off.
really, I can name a lot. Pretty much any car with a manual blower will supply warm air if the vents are open, set to hot and the blower is off. By your own admission you say to any noticeable extent, sure it's not going to be like a log fire, but its warmth none the less. Will it heat a cabin, no, but the airflow over a car whilst moving will push warm air from the engine into the cabin. It's not that hard a concept to grasp.
