About 48,000 BTU

You need to have load calculations done. Insulation, windows, location, outside temps, shade conditions, etc. will all affect the answer. For a shop with no windows and very good insulation or in a moderate climate, 48,000 btu may be sufficient. There are heating and cooling load worksheets available on the web if you know the R-value of your insulation and window type.
