Does anybody have a good link/program for a good heat loss calculator to size a heating system? Thanks

    http://www.slantfin.com/homeowners-page/ipadapp.html is a good place to start.

    Only complaint I have with the Slant/Fin program is that you cannot give the windows a cardinal direction. You posted this in the steam section. Are you replacing a steam boiler? If so, a heat loss is not necessary. You'll need to measue radiators to get the correct boiler size.

    If you need help, I've been known to do heat load calculations for people.

    I'm curious. Are most guys recommending Slant-Fin's calculator because it's readily available for anyone to use? And free?

    That, plus the fact that it's potentially comprehensible for a homeowner.
