# How much heat loss for this space?

Remember, you get what you pay for...

Where is the value of having something done for nothing?

We are EAGER to help, but you've had your share of "free advice" from this place, have you not??

I'm a builder, not a heating pro, but I wonder whether I can get somebody to run some calcs for me that can help steer our project.

For a one-story house with walkout basement below the main floor, my question relates to the one large common space (foyer-stairwell-greatroom-kitchen) that is on the main floor.

The rooms-without-walls space consumes 574 square feet of the main floor, the rest of which is just a small hallway, bath, and bedroom.

Here are the facts on the space: 574 sf floor/ceiling, ceiling entirely under roof and insulated to R50, exterior walls total 88 ft of length (all 9' high), insulated to R21, ceiling height averages 11'-5" (vaults from 9'0 to 13'9), window and glass door gross area is 227 sf (U = 0.35 low e2 argon-filled glass).

The siting is such that none of the windows face south. The house is in the deep pine woods, and the winter design temp is somewhere around -15 degrees F.

I am looking for some clue as to how much heat is going to need to be pumped into this space, so I can see how to do it with either HW baseboards, or panel radiators, or a combination of the two. The answer may greatly affect my design for window locations, wall trim, etc.

All help is appreciated.

I know about the heat load req to size boiler, but . . .

Thanks for the reply. I really wasn't asking for help sizing a boiler,........

Id be real surprised if someone here does it for you.

Try the \"Heat Loss Calcs\" Tab

above on this site. Go ahead! No fear- you can do it!

Follow the directions and walk yourself through it. Don't forget infiltration and any other heat transfer surfaces such as over a basement or crawlspace.
