1.
The water vapor in the pellet stove exhaust is actually visible. That thing is so efficient that it normally only has visible smoke on startup.
2.
Both the pellet stove and the boiler need to run in order to keep the house comfortable. (Technically the boiler would do the job just fine by itself, except that family members on the 2nd floor would be wearing shorts while the folks downstairs would be wearing sweaters. Oh, and I'd have to own a very productive oil well to pay for the fuel oil.)

The dog actually does his business outside in a timely fashion rather than looking like a wooly statue sniffing the breeze for 10 minutes before finally pooping.
4.
Dog poo must be removed quickly from hard surfaces like sidewalks before it freezes in place. (Although a few frozen turds might discourage the neighbors from dragging sleds down the sidewalk when it snows. It is quite annoying when they do that, because it glues the snow to the concrete.)
5.
It becomes necessary to knock over the ice stalagmite that forms below the next door neighbor's furnace exhaust before it grows so tall that it blocks the exhaust.
6.
The cars don't start very well, and once they do it takes at least 15 minutes of driving before the heat works. The heat also gets left on maximum temperature for the whole trip, and passengers suddenly think lap blankets are stylish.
7.
You can make seafood, chicken soup, ribs, whatever you desire without making sure that trash day is the next day. Trash in the outside can doesn't stink, because it's frozen solid. However if you live somewhere with bears and other predators, you'd better have tamper proof cans.

Meal planning includes thoughts of which things will take a long time to bake, thereby heating the house some more.
9.
It is really cold outside when the cat is not at all interested in sneaking outside and can't decide whether to sleep in a bed with the electric blanket running, on the hot register, or on the couch in front of the pellet stove. Poor Duke - so many choices, what will he do? What am I saying? He's a cat; he'll try all three, and then try to climb into the clothes dryer just to be annoying.
