Hi Boondox:
My wife and I heat our entire house, much to the dogs delight with an Englander Pellet Stove. We have had the stove for over 5 years and it's paid for itself many times over.
We have the stove located in the living room and to heat the upstairs, we keep the door on the staircase open. My wife like to keep it about 72 degrees inside.
We use about 4 tons of hardwood pellets a season. At $150.00 per ton, that's a lot less than the price of propane or even natural gas, both of which have seen pretty hefty price increases lately. I tend to add a mixture of shelled corn to the pellet fuel in the colder months. The corn burns hotter than the hardwood and gives more heat.
I heat my shop with propane so I do use about 400 gallons each year, plus now, our standby generator is hooked to the propane supply also.
At one time, we heated with a woodstove, but I find wood to be pretty messy in the house. The wood has bugs in it and it's really messy cleaning out ashes.
The pellet stove on the other hand is an easy cleanout. You just shut it down for about 4 hours and vacuum it out with a shop vacuum.
The Englander looks like a regular woodstove. It even has a glass door on the front so you can watch the flames.
