Radiant Heat Transfer Plates
These PEX heat transfer plates are manufactured from aluminum using stamping method and are designed to improve performance of the radiant floor heating system by dispersing the heat from PEX tubing into the flooring above. Omega-shaped. Made in the USA.
About Heat Transfer PlatesPEX heat transfer plates improve performance and comfort levels produced by the radiant floor heat system. They are snapped over PEX tubing and secured to plywood or wooden subfloor surface with nails, screws or staples. By dissipating the heat from PEX to the flooring, plates allow for a more even distribution of heat and effectively reduce or eliminate cold spots on the floor. With increased heat transfer efficiency, the system can run at a lower supply temperature, resulting in lower operating costs.
Aluminum stamped heat transfer plates are 5" wide, have a nominal thickness of 0.019" and feature an Omega-shaped tubing channel, which has better heat transfer efficiency and installs quicker and easier then U-shaped plates.
Heat transfer plates can be used both for subfloor installations where PEX tubing is attached to the bottom of a subfloor, and for underfloor (“sandwich”) installations where PEX is installed between the subfloor and finished floor.
When installing these plates, avoid cutting them, as abrasive edges may damage the tubing when it expands and contracts. If cutting is required, the tubing channel should be reamed out with pliers and smoothed with a round file.
Frequently Asked Questions about this product: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, to perform your own calculations, considering that a single joist bay will have (2) parallel runs of plates spaced at 0.5"-2" apart and that a “buffer” space of ~1.5ft on both ends of the bay is needed to route the PEX pipe to the next bay.
Q: How to reduce noise associated with PEX heat transfer plates?
A: Applying a thin layer of clear silicone glue to the tubing channel prior to installing PEX will help to reduce noise level. Some manufacturers also recommend securing only one side (wing) of the plate, leaving the other one hanging and thus eliminating direct contact of PEX tubing with the subfloor surface.
Q: How far apart should I space these plates?
A: For parallel runs, radiant heat transfer plates should be spaced at 8" apart OC (On Center).
