Heat Loss Program

IronmanIronman Posts: 2,270Member ✭✭✭
Any of you guys know of a simple and cheap heat loss program that I could recommend to a home owner who wants to do their own calc.? Their house is so cut up  that it would literally take may a day to measure up everything and another day to run all the numbers. I'm swamped right now and don't have that kind of time.

Preferably a program that you plug the numbers into instead of trying to draw the layout with a mouse like Wrightsoft does.

You can choose to do what you want, but you cannot choose the consequences.

    Heat Loss Program

    Hi- You might want to take a look at this program.

    Very easy to use. The Residential version for commercial use is about $400 but they have the same version available for the homeowner at $ 49 which is useable for 2 months. There is a trial version you can download to check out the features.

    Try Siggy's Heat Load Pro

    I have the free version of this that comes with his book. It is enough to tease me and to convince me that if I were to do this kind of thing on a regular basis (I am not a professional, so I could not quite justify the cost), I would want the commercial (professional?) version of the software. The free version handles only two rooms on each of two zones, and you cannot save your work. It gives you a good idea of what the software can do, though.

    I think the book alone is well worth the money, so for me, the educational version is free.

    Heat Loss Programs:

    The Slant Fin program is great. I've used it for years. I'm sorry it isn't available anymore.

    I used the IBR/Hydronics Institute system for years and years and always wanted to find a program that was based on IBR. Every one I tried was for AC or warm air. The S/F program is actually the IBR method. I have it on my laptop and I can go through a house quickly. I've never found anything as easy to use.

    But, that's me.
