I really love my Woodstock. Fired her up tonight when spending time down here watching a movie. A wonderful little space heater and on natural gas, doesn't add much to my heating cost. This is vented outside, which to me is still preferable for those willing to spend a few bucks extra on installation. If you plan on staying in your home for awhile, the extra cost is well worth the lack of moisture and peace of mind of not having unwanted by-products in your space.
