Garage addition, furnace question

[wallster]

Hello everyone! We built our garage in 2012 and now we're adding on. We have a 24' x 24' garage (576 cu ft) with 8' ceilings, drywalled walls and insulation in the crawl space and walls. Our 50K btu/hr Mr Heater BigMaxx (natural gas) heats it up very well (and the doors are also insulated). We're adding on a 20' x 24' addition that will be insulated and drywalled as well. That makes the overall dimensions (24' x 44' or 1056 square feet).
Since the heater is rated at 50K BTU, and is designed to heat 700 square feet, will it work based on the walls, ceiling and insulation or do I need to upgrade?

Thanks,

Wally

Location? I'd try it and see, my guess is that it will be OK the vast majority of the days. Especially if you insulate and air seal well.

Should be fine, especially in temperatures above zero.

Location would help the experts.
It will likely heat the area , but may be slower to get there, which isn't necessarily a bad thing

Thanks for the reply. The heater is located towards the rear of the garage that will become the middle of the garage and the garage is located in Buffalo NY. We get a few days that are subzero but our winters have been pretty mild compared to the past. I leave the thermostat on 56 degree and if I'm spending some extended time in there I bump it up to 65 degrees. It doesn't run long or often unless it's unusually cold outside.
