2ft long x 5" wide, 1/2" PEX Aluminum Heat Transfer Plates (100/box), Omega-Shaped, Made in USA
Brand: Everhot
Part#: HTP122-100
Temporary Out of Stock
Usually ships: Upon availability

2ft long Heat Transfer Plates are manufactured from stamped aluminum and are 5" wide.
Nominal thickness of these plates is 0.018".

Compatible with 1/2" PEX tubing (5/8" OD).

Can be used for subfloor or sandwich type radiant heating installations to improve heat transfer properties of the system and lower the water supply temperature, thus reducing the heating bills.

Recommended spacing for parallel tubing runs is 8" OC. Edges of the plates should not touch each other or intersect.

Everhot Omega-shaped heat transfer plates offer superior heat distribution when compared to V-shaped or U-shaped channel plates and are manufactured in the USA.

Great price for a good product
"I am using this for a ""sandwich"" radiant floor install, where the plates are installed above my subfloor with 3/4in boards filling in between the plates, and then hardwood flooring will go over the top. The Omega shaped groove is important, and the 1/2in pex snapped in to these plates as expected. These plates are thin aluminum, compared to others that I found available, but my research indicates that there is only a little gain in performance, for considerable added cost, when considering heavier gage plates, so I am confident that this is an adequate and cost effective option. I will be ordering these for the remainder of the installation."

Best price I could find online
There was no place local that had these in stock & after shopping around online, PEX Universe was by far the cheapest. These plates have clean edges but they're still stamped aluminum so do be careful when installing. The omega shaping is great for getting a good bite around the tubing for good thermal conductivity. I'm running a bead of 100% silicone before putting the tubing in to provide even better thermal transfer & to eliminate any noises caused by aluminum & polyethylene expanding & contracting at differing rates. I'm also putting a thin layer of silicone on the top side of the plates that touch the underside of the subfloor for the same reasons. You can buy heavier gauge aluminum plates but they are far more expensive & from what I've researched don't do all that much better than the thin ones like these.

Great product
This is the first time installing radiant floor heat and these plates went up with ease. The feel heavy enough to conduct the heat across the floor, yet they are easy to work with.

Works good
We used these with our radiant floors using the sanwitch method. We built most of our plates using aluminum flashing from a hardware store which is much cheaper, but if you don't have the time and patience to do it yourself this is the way to go. Saves lots of time and pex snaps in nicely. This was one of the cheapest places I've found to order these.

Ask a Question
You say "Edges of the plates should not touch each other or intersect." Why is that? And is there testing that backs that up?
Helpful? Yes 5 No
The main reason why plates should not touch or overlap each other is to avoid any noise due to expansion and contraction with temperature changes in the system.

With the heat transfer plates fot 1/2 pex how far should they be spaced apart end to end
Helpful? Yes 4 No
About 2"-3".

I plan on using these in a sandwich installation. Is there anything I need to do to with these plates to prevent noisy temperature changes?
Helpful? Yes 1 No
You may add a few beads of silicone sealant into the plate channel where PEX tubing goes.

How are these plates attached to the subfloor for an underfloor heating application?
Helpful? Yes No
With screws or staples.

How much heat do they give off? BTH/HR/°F or W/m*K
Helpful? Yes No
Plates themselves do not produce heat, they simply facilitate heat transfer from PEX tubing surface to the flooring surface. Since aluminum is a much better heat conductor than air, heat is transferred more efficiently (faster and easier) and therefore, less energy is wasted. The advantages are: (1) Radiant system can run at lower temperatures - energy savings; (2) - Response time is increased - time factor; (3) Floor surface is more evenly heated - comfort increased; As for the output - it will depend on factors such as tubing size, flow rate, water temperature, etc.
