Manifold piping

John Felciano

We've done a couple jobs like that with 3/8" tubing, without any problems.It's allot easier to pull and as long as the load is small it should do the job.Just watch your pump size.

Manifold piping

to radiators. We've got a house coming up soon in San Francisco; the basement is radiant in a colored slab, the first floor is radiant staple-up and the upper two floors are radiators. I want to install manifolds on the top two floors and then pipe the radiators off the manifold.

We normally would use 1/2" PEX, but 3/8" would be a lot easier. As long as the radiator is under 7,000 BTU's, I don't see a problem. Has anyone done this? Pros and cons?

Best wishes,

Alan

If you're woried about low flow...

just design at a higher delta tee. "Thou shalt design at 20F delta tee" is not the eleventh coommandment.
