I would like to install radiant tubing w/ transfer plates under the floor. The floor joists are 24" OC. Transfer plates are 4" x 48". I'm using 1/2" PEX.
I was told by suppler to space the tubing 8" which would give me 3 runs of tubing per bay. Any harm in reducing the spacing so I could have 4 runs? This would essentially be 2 loops which would be easier to install.
Transfer plates would not touch. It would seem I would be putting more heat into each bay. It's perhaps overkill. My concern is whether it will work or affect heating capabilities.
I intend to insulate each bay leaving at least a 2" air gap beneath tubes.
Thank you.
