I purchased a house built in the early 90s and it has a wood stove in the basement (which was a major selling feature for me). However, after looking all over the internet I can't seem to find anything out about the stove. It's a Paragon brand model P-80 or P-60. I'm attaching a picture of the tags on it. Can anyone tell me anything about this brand/model of stove. Is it very efficient or should I look to replace it soon?
