So, we love our first pellet stove so much, we're thinking of getting a second one for the walk-up family room that's 24x24 with cathedral ceilings and lots of windows. The first stove is in the livingroom and heats that side of the house very well, including heat rising upstairs. This second stove is strictly for the family room where the kids hang out. I'm not looking to spend a lot of money on a fancy stove since it'll only be in use when the kids are home from school and weekends. Of the four listed above, can you tell me which one you would pick and the reason why? Those are the four that's readily available to me and I can have installed earliest next week or the week after. I'm looking for most reliable and easiest to operate/clean. Thanks!!
