Pex in heating system

Dave Belisle

We use PEX all the time for baseboard zones.The copper drops through the floor and then we change to PEX.

With the new energy codes builders will insulate there floors and not there foundations . So we are putting the PEX up in the joist above there insulation so we don't have to insulate our pipes.

On indirects we come up to the joist with copper to keep it neat and the run with PEX.

pex is rated at 200 degrees at 100 psi I think. Why not? WW

At 20 F the glycol

content must be considered...

I'm sure the typo meant 200F NOT 20?
