I have a room in my pole barn that I am building for my man cave. It is 14 x
20. I have R19 insulation in the walls and R38 in the floor and ceilings. It
is on the second floor and the ceiling is about 7' tall. I am located in
central Ohio. How would I figure out what size heater I need to make it
relatively comfortable to work in when it is cold out. Near as I can figure
I need about 14,000 BTU, do you think this is correct?
Thanks,

I think you take (square feet of surface X deltaT inF )/R-value = btu/hr
