Don't know if there is a formula for this and I'm not looking for a typical
heat loss calculation. The scenario is this: Garage is 24' X 24' with 12'
ceiling. There is sheetrock and insulation in the ceiling and three walls.
The garage has two standard overhead doors. Temperature is aprox 32 degrees.
I want to raise the temperature to 60 degrees in about one hour. How many
BTU's do I need?


Thanks for any help, Roy
