Heat Loss Program

I relied on my copy of the Slant/Fin heat loss program that I had for years and now I have a new computer with a new operating system (Windows 7).  I'll be trying to move it over, but in the event that I can't, does anyone know of an equal?  It was easy to use and FREE!

    not free, but very

    affordable. This ids the heat load program that Siggy built. I like the wall input screen. It allows you to build up any wall including basements with different bury depths, etc.

    I believe Upinor has one.

    I had one installed in my laptop which has since crashed and I have not re downloaded it. Check their site. It is FREE!
    Too bad common sense isn't very common.

    Thanks, guys.  That helps.

    I have since been able to start my computer in "XP mode" and salvage my Slant/Fin program.  In time, I'll upgrade.

    All the best,
