Even if the garage is attached, there will be an exterior door between the garage and the house proper that will be as heat loss resistant as your front door. So I don’t know how you get anymore heat loss than you would from any exterior door in the house. In fact, that door will have LESS heat loss than your front door because it’s shielded from the elements that your front door isn’t.
Honestly I was half joking, but seriously don’t most homes have extra insulation between the garage and the rest of the house? Are you guys heating your garages?
They do. A garage with a closed door acts like an air gap, meaning you get some extra insulation for free. It’s far from perfect, as the garage door itself can’t have particularly thick insulation, and the interface between the door and the frame is difficult to seal completely. Still, even an uninsulated garage with a closed door will typically be a bit warmer than the outside in the winter.
What’s special about the door or do you mean just opening it? If the latter, that still won’t prevent it from collecting at the ceiling and you’d better hope you remembered to open the door.
The majority of garages I’ve seen have a garage door so the fumes don’t just build up in the garage.
Which means that your home then has increased heat loss because the garage door is open.
Would you have a large impact on your home from having your garage open for 15 minutes or so every day?

Eh, I don’t even have a garage, and my place stays warm just fine. It’s just a few minutes
What the hell are you talking about? Listen to yourself
