Chris, I too have the Oneida unit and can't say enough about how pleased I am with it, in a commercial environment. Have you considered a local HVAC supplier??Originally Posted by Chris McKimson
I ran a 7" main around 36' with 5 x Y's reduced to 6" and down to 4 or 5" at some of the tools, there is a heck of a lot of pipe, Y's, elbows etc. I suspect I have about $900.00 Canadian which was a huge savings for me.
I did look at PVC however I had PVC with the previous system and in the winter, with the wood stove going and the DC, man if you even came close to the pipe the static charge was enough on a couple of ocassions to burn my skin.....aside from being constantly annoying I didn't think it to be a real safe option for me.
Good Luck!
Andy
