Hi Everyone,

I have found your posts incredibly useful and informative and am now hoping I might get some advice! I am a new-owner/builder and was wondering what the best radiant system/tubing you would use for a new construction large home. We will have a large great room with many windows! Basement,main and upper level will require radiant and currently we have a 16 zone design. A big caveat is that we could get the pex for free, but don't want that to be our main motivation. What would you do?

Thanks again,

Sarah
