Question Manual J calculation help...

We're refinishing part of the basement and going to add heat (NJ - nuff said). We already have 2 baseboard hot water zones so the basement will be its own new zone. I can do all the installation and piping easily enough but can't do the calculations for baseboard requirements. There is NO heating guy or plumber to be found that I can pay to do the calculations unless they do the whole shebang. Too many big jobs out there for them...

I got some free software from Slant/Fin, but I don't know enough for the proper inputs. I'm trying not to buy expensive software for a one-time calculation. Does anyone know a source where I can get the calculations to determine how much baseboard is needed so I can get to work on it?

Thanks guys!

If $50 isn't too expensive, you can download & run the program from You get support along with the program.
