I was wondering what the best course of action for me to take to help heat my house during the winter months. I live in Western Maryland where winter months average around 20-30 degrees, lows in the teens to single digits every once in a while. My house is a rancher with 13' cathedral ceilings on half the house with a square footage of approximately 1650 square feet. The house is also insulated fairly well. I currently have a wood stove in the basement which is also 1650 square feet so realistically I am heating approximately 3300 square feet. The basement is currently unfinished but will be finished in the future. Would it be better for me to shell out the money for an outdoor wood stove or invest in a high priced cat stove i.e. Blaze King. I checked the prices on the Blaze King's and they are really pricey but if I save in the long run it will be worth the investment. Any input would be great.
