Thermal transfer plate
Thermal transfer plate also called Heat Transfer Plates
They allow for a more even heat distribution across the flooring surface if compared to staple-up tubing installation.
They serve as a support for PEX tubing and eliminate the need for additional installation accessories.
They allow for a lower fluid supply temperature, thus increasing the radiant heating system’s efficiency and reducing the costs of heating.
Aluminum Heat Transfer Plates are a thinner, and are commonly used in sandwich-type radiant floors, where PEX tubing is placed between the finished floor (i.e. laminate, hardwood, etc.) and the subfloor. These plates are wide and short, which makes them ideal for such projects and allows for more versatility in installation.
The following image illustrates the heat transfer process during joist space installation using heat transfer plates. The image speaks for itself and gives very good reasons to consider using the heat transfer plates wherever it is possible.
