I have been heating with a 30 year old Vermont Castings vigilant catalytic stove. This stove has been an alright heater but has been horrible for creosote production and we recently had a chimney fire even though i had just cleaned the chimney a month earlier and am using year and a half old wood. so, i am in the process of replacing my stove and pipe. The footprint of my house is about 800 square feet and it has a vaulted ceiling with a master bedroom loft for a second floor. The house is not the best insulated house i have ever been in. Given that i live in a very cold climate (northeastern minnesota) and rely on wood for my primary heat, i want to get a large stove that can easily heat my space. I am currently looking at four types of stoves. The Regency 3100, Regency 2400, Napoleon EPA1900, and The Enerzone 3.4. What are people's thoughts on these stoves? am i on the right track with these? Please let me know because i really want to make an informed decision that results in a good quality, high heat output stove that lasts for years and years. Thanks so much. appreciate it.
