Stamped Heat Transfer Plates
Stamped Heat Transfer Plates are 5" wide x 24" long. Manufactured from aluminum and have a nominal thickness of 0.019". Tubing channel is omega-shaped.
PEX heat transfer plates are commonly used in radiant floor heating projects ("sandwich" type or bottom of the subfloor).
Q: How many plates will i need?
A: A rough estimate for joists with 16" OC (On Center) spacing, would be (60) 2ft plates for every 100 sq. ft of space.
It is recommended, however, do do your own calculation, based on the fact that there will be (2) parallel runs of plates in a single joist bay, the plates are spaced a couple inches apart and there needs to be about 1.5ft of space left at the beginning and the end of the joist bay to allow for PEX tubing bends and turns.
Q: How to minimize noise associated with stamped plates?
A: Apply thin layer of clear silicone glue to the tubing channel to minimize noise. Some manufacturers may also recommend securing only one side (wing) of the plate, leaving the other one hanging and thus eliminating contact of PEX tubing with the subfloor.
Q: What should the spacing be between plates?
A: For parallel runs, PEX heat transfer plates should be 8" apart OC (On Center). Leave ~1" spacing between plates.
