how big is to big?

Hey guys was just wondering I have a 20x24x10 with valted ceilings. Gonna fully insulated I wanna know what size (btu) natural gas heater do I need for a radiant heater to keep it nice and warm?

I would go with forced air heat, lots of calculators online for figuring that out

Radiant heat like any type of heat has it's pro's and cons. Typically more efficient than FHA but more expense up front.

I would guess 45k would be more than adeaquate without oversizing.

I heat my 24 x 24 x 10 nicely when it's 20* outside with a 25K BTU radiant tube heater. I went small mainly because with a 10' ceiling, I didn't want to bake when I'm working under it.
