I would like to do a infloor heat system and could use any tips on best method. I will use a natural gas fired boiler and a circulating pump. This will be a 1000 sq.ft. pad insulated with 2" Styrofoam insulation under pad. Looking for possibly a do it yourself guide for the in floor lines.
Google is your friend on this one. I searched "hydronic heating" and came up with all the info you could possibly need.
I have helped put them in on the last few Habitat for Humanity projects I volunteered on and we did all of the prep work including the fill, r10 (2") Styrofoam, and wire grid. The plumbers then came in and tied the pex to the wire grid at the spacing specified. The volunteers then came back in with a skilled concrete guy and did the pour. Every home owner loved it.
It is definitely a DIY project. The only other thing the plumbers did was to pressurize the system I think to about 40 PSI and leave a guage on it so we could see if we damaged it during the pour. I think the inspector also used it to verify the system integrity.
Good luck with it.
