I am hoping that the supply of pellets is not going to be an issue for years to come. At the very least, we will have 2 ways to heat the house. Whichever is cheaper is the one we can use. I am looking forward to that hot air coming out of the stove and not hearing the furnace run! When I had looked at the Quad's the dealer checked the temp of the air coming out of the stove. It was up near 150 F. Sounds good to me!
