Is it harmful to warm up a car with the heater turned off?

Hello,

Given the relatively cold temperatures this time of year, I've gotten into the habit of turning off the heater until the engine reaches around 70-80°C as indicated on the display.
The engine gets noticeably warmer, my fuel consumption decreases on my route (30km) by 5-10%, and I can easily do without the cold air at the beginning.

But: Is this somehow harmful to the engine? Could the faster heating, for example, damage the cylinder head gasket (due to different expansion of the engine block and cylinder head)? Or could there be any other problems?

Thank you.

problem 1 (less severe): you are cold

problem 2 (very bad): your wife/girlfriend/someone else is cold


-> What do you do when the engine starts on a hot summer day?

question answered?

See you, Gremlin

Problem 1.5 (good for the engine): You're getting a cold in the cold interior and leaving the car running!

Problem 1: I also get cold even when the heating is on. In fact, I get colder, because it gets really drafty when the engine is cold. That's why I don't mind.
And because the engine heats up faster when it is first turned off, it actually results in warmer air coming out sooner.

Problem 2: I take it and put it in my warm right arm.

During the peak summer months, the engine's temperature rises. Whether it's going from 20°C or 10°C to 90°C might not make a significant difference. But what about at -10°C?
Well, then I'll just keep going. And if the ZKD expires, I will sue you.

Hm, dann solltest du mir so schnell wie möglich eine Rechnung ausstellen, aber ich glaube kaum, dass du Gremlins und meinen Stundensatz bezahlen könntest....

Main thing is, it's lower than the VW. Then one could really think about it if needed.

Forget it...

...your budget exceeds the necessary food expenses....

btw: what about a stand heater?
