The only thing I have is my Cayenne keeps the water circulating and heater running after shutting the car off until the water temp drops enough to match the outside temps. Very nice to come back to a warm vehicle.

My house does have a wood burning gas fireplace that might warm a large area. Don't know as I've never lit even a match in it or even opened the flu. Now, 20 years since moving in, would be afraid to light a fire in it until after having a chimney sweep clean it.
