Which Radiant Heat Transfer Plate is Right for me?

    There are a lot of variables to consider when trying to decide which radiant heat transfer plates to use for your project.  One of the main things to keep in mind prior to starting is what products are currently on the market.  For example, depending on which tube size you were hoping to use, a transfer plate may or may not be available to compliment your installation.  Here I have compiled a list of plate sizes that are widely available for ½” PEX tubing and the pros and cons of each plate.

4’ length by 4” width omega shape

                                         

Pros:  Omega shape maximizes thermal diffusion as there is less space between the tube and the plate.  The omega shape also allows for easier installation as the plate “snaps” into place with the tube, when compared to “u” shaped plates.  Longer plates also reduce gaps between each plate, as there is less space for heat to escape when compared to shorter length plates.

Cons:  Longer plates may be more difficult to install than shorter plates.

2’ length by 4” width omega shape

Pros:  Omega shape is ideal for all installations in that, as mentioned above, they maximize the amount of heat produced and are easier to install as the tube stays in place while you work.  The main benefit of shorter lengths is ease of installation.  Overall, it is a lot easier to lift and keep a 2’ plate in place over a 4’ plate.

Cons:  While the length allows you install the plates easier, it is not ideal as far as reducing thermal gaps in your project.

2’ length by 4” width “U” shape

Pros:  U shaped plates do tend to be cheaper in price

Cons:  Though you’ll save a buck or two U shaped plates are not ideal for projects.  Your tube will not easily stay in place as you’re installing, which could prove frustrating.  Also, the tube may sit further away from the aluminum.  This will cause thermal gaps and the money that you may have saved by going the cheaper route will be lost when the bill comes.

4’ length by 5” width omega/U shape

Pros:  Benefits from 4-foot length and omega shape as mentioned above. 

Cons:  Some people may think that paying more for a 5” wide plate over a 4” wide plate is beneficial as you can cover more ground with the plate.  What some fail to realize, however, is that most of the heat is dispersed where the tube meets the aluminum plate.  Paying more for a wider plate does not really make much sense as the aluminum only aids in heat being dispersed throughout a certain radius.  In other words, this is where you can save the money on your project. 

4’ length by 12” width omega shaped plates

Pros:  You will definitely cover more ground with these plates.  Each plate has two omega shaped channels that snap into the tubes.  Along with the length and omega shaped benefits, you’ll have your project done in less time. 

Cons:  These plates due tend to run a bit higher in price.  Also, the size of the product probably makes installation a bit harder.
