1500 but never run on highHow many watts are the food warmers?
I just installed a 9000 BTU unit (smallest one you can get) in my 1-bay garage. All the calculations I found showed the 9000 BTU unit was more than enough for my 225sq ft space. Even with an un-insulated roll-up door and un-insulated attic (just 5/8 drywall), it keeps it 72 degrees just fine. I think if you have 96 sq ft, then a 9000 BTU unit will be more than enough even if it's leaky and has windows, etc.
