I see a lot of computer heat loss / gain programs and i wondering which are the better ones? Are they simple or user friendly? and how much do they cost?

programs

I have used Elite software and others,I now used hvac-calc
very easy to used and price right.But it will not do audits
Other then that worth the money.Check it out at
WWW.hvaccomputer.com down load and give it a try.

I like...

the FREE ones. They make the most cents!! (pun intended...)

We tested a whole bunch of them once from different sources against the same floor plan, and they all came real close to each other. Less than 2% difference as I remember. It's basic mathematics. Infiltration is really the only variable, and they all treated that fairly judiciously.

The major tubing manufacturers also offer their own versions of programs if you indulge in their tube.

I like Wirsbos program.

My designer/estimator likes the Kitec program, which runs on Exel.

There are some out there that will actually figure out how much of what lengths of rolls you need and manifolds and blah blah blah...

Trust your instincts. They're natural.

Heres a Google Search of free heat loss programs. http://www.google.com/search?hl=en&ie=UTF-8&oe=UTF-8&q=free+heat+loss+programs&btnG=Google+Search

Enjoy, and learn!
