Do you think 2500 is too much to pay for a medium sized cast iron pellet stove? I have this one room that is always cool in temperature. Has a lot of windows. And has an eight ft. ceiling. Sq. footage is 300. I'm thinking any stove I buy would run you out of there. Unless its on low all the time. Hate to pay 2,500 just to heat it. This room was an add on and the house furnace ducts couldn't be run to it.
