I need to determine the BTUs for a 16x12x9 ft room w/ three 3 6x3 ft double-paneled windows, with wall insulation fair/average in southern Wisconsin, hydroponic heating system.

With that much glass in one room and being in a colder climite, I would have a heat load calculation done on the room to be sure. Search the net for home heat load calculations.

Hello and Welcome big_daddy to the Do It Yourself Web Site.

On average and with all dimensions taken into consideration, the formular is:

40 BTU's per square foot.

Therefore, {if my calculations are correct... }

16 x 12 = 192 sq. ft. x 40 btu's = 7,680

The amount of BTU's needed to heat that room should be 7,680.

Regards & Good Luck
