How many square feet will a 20,000 btu natural gas radient vent free wall heater with blower- heat?

Question

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 to place it to get the most heat for the area. ( inside the home ) Thanks!

Answer 1

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
