I was watching this old house last weekend and rich T. had this guy on there with a new program that was awesome. He put the blueprints for the project into his computer along with window data insulation data Square foot data and it told him exactly what size heating and cooling unit to go with. But this program want one step futher. It actually showed the radiant floor heating system room by room laid out in the computer plus the cooling system laid out also. So all you have to do is look at it, It will show how to loop the radiant floor heating in each room. Also where to put the duct work in all the rooms. There going with high velocity for cooling which in a way looks kind of like the duct work on back of a dryer. The program will also give material list calculation and everything. It was a awesome program they showed on a laptop computer. I wrote down the companys name.
