Heating Help

yea i basically selected the partially below grade and the heat loss was huge and it calculated like 74 feet of 15. The basement loss is around 40,000btus I changed it a bit but it still shows a great loss. the foundation is 32x22 7 ' ceiling.

I think what your doing is entering the foundation in as 8" block.If you click on the "poured concrete foundation"the window will allow you to select partial above and below grade.This will default to a lower factor.When I did that I came up with a load of 20K.I included 4 windows single pane @ 4sq'/window.Like Kevin said play around with it.It is a good program and you can't beat the price:) cheese

one more thing

I didn't enter an infiltration rate for that.....so do it yourself again:) cheese

Below Grade

You should be entering the average exposed area on a basement if you are not doing so. If you have a 7' basement and only 2' is above grade you should be entering the ceiling height as 2'. If you have a sloping property line you should use the average height that is above grade.

Slant fin Hydronic Explorer question

When sizing a heat loss with this program, are we supposed to size use the basement as its own floor? This is how my hvac-calc program works and the basement losses are usually pretty small. I used the Slant fin progam and came up with huge losses that required lots of baseboard. Any ideas?

own floor....

it gives you lots of choices....exposed wall,partially exposed wall,foundation.. slab;insualation above,below,edge...play with it a bit. kpc To Learn More About This Professional, Click Here to Visit Their Ad in "Find A Professional"
