Understandably, it depends on insulation and other comparables, Like a home, compared to a garage or shop. I mean just roughly, so I know where on earth to place it to get the most heat for the nouns. ( inside the home ) Thanks!
Answers: You want to look at BTU output not BTU input first.Roughly you can figure 20 BTU per square foot if it snows in the winter time
