Pellet stove air intake

They recommend pulling air from outside for combustion instead of room
air. Doesn't it take more energy to heat zero air than 70 degree air?
The dryer doesn't make a vacuum in the house why should the pellet stove?

dryer certainly does make a vacuum in the house. where do you think all that air going out the vent is coming from?

My pellet stove uses inside air for combustion and I don't have a problem. But my old farm house in not all that air tight either.

Both of my pellet stoves are inserts in a central chimney. Outside venting isn't possible, and they work fine. And, like the last poster, this isn't an air-tight house.

Yeah, it's terrible. His house is inside a sealed garbage bag. Every time he runs the dryer, he passes out.

The dryer is certainly making a slight vacuum. If you are blowing air out, it has to be replaced somehow, usually through all the tiny leaks you have. The pellet stove (or woodstove, oil burner, gas furnace) will be venting the exhaust to the outside. As long as air is going out, more cold air is coming in. By moving the combustion air inlet to draw directly from outside, you don't take the already heated air and exhaust it to bring in new.
As for the energy, yes and no. You need a certain amount of Btu to get the air to the point it can be used for combustion. However, you are also going to take air that you paid to heat already inside the house and heat it up to burn and, as I sated, it will be replaced by cold outside air. It can even create serious drafts in some homes, depending on construction.
No house is air tight. Do some searching and you'll find information on testing that is done and how they house can be pressurized to find the leaks. Start here

Years ago I lived in a house that when the bathroom vent was on, it pulled air from the fireplace down the chimney. I wondered where on earth the smell of burnt wood was coming from.

My point was that, if the outlet is in the middle of the house, like our center chimney, there's no way to direct outside air to the comubstion chamber without being ridiculous. Pellet stoves draw combustion air from the bottom anyhow, where it is coolest in the house, and just that draw tends to pull warmth down from the ceiling to the living zone. A pellet stove is very different in dynamic from a wood stove; more like your oil or gas burner, which don't recommend outside air.You can hold your hand on the top of a pellet stove all day without any more harm than feeling ridiculous.

Want me to send you a photo of the outside air intake on my oil burner? Or from the gas burners at work? All installed at the manufacturer's recommendation.
It may not be easy to install in your case, but the reason it is recommended does not go away. Every cubic foot of air that goes up your chimney is replace by an equal amount of air from outside. Just one of those laws of physics that we cannot get around.
Oh, and my oil burner is in the center of the house and yes, the fresh air inlet is ducted to it via 2" PVC.
Outside air ducting has another benefit in that when the stove or burner is not in operation, there is no heat loss up the chimney from air just being drawn up through it and wasted. This saves heat and the associated costs.
Personally, I don't care what you do in your house but now you know the reason for it

I was thinking of putting the air intake up through the ceiling into the attic. There outside air can be drawn in from the roof vents and any heat leaking up through the floor can be sucked back down. Since the ceiling is right above the stove it's a short run.

I don't believe my house is air tight, especially with a cellar drain. There is no trap on the cellar drain because it don't go into a sewer. I'm sure air comes up that pipe just fine. There is a screen on the outside end to keep the little animals out. I guess it's too long a tunnel for the bugs.

Who can afford wood pellets or corn now at these prices? I thought these pellet stoves had gone away by now?

It wouldn't be for burning, it would be to prevent you from sucking your windows out when you turn on the dryer and the exhaust removes all the air from your house.
