Under Floor Radiant Heating • Free samples of ThermoFin are available from the website at this • link: http://www.radiantdesignandsupply.com.... • Contact the manufacturer, Radiant Design Supply, formerly Radiant Engineering, radiantdesignandsupply.com, to purchase ThermoFin, or for more information on custom design of hydronic radiant heating systems. Patented ThermoFin is made in the USA. See the Heat Exchanger blog on the website for a product comparison study. • http://www.radiantdesignandsupply.com... • Unlike gypsum, the ThermoFin plate temperature remains very uniform even at high heat flux. This kind of performance is due to the plate thickness and the conductivity of aluminum. By contrast, gypsum and concrete do not conduct well. • If you need to cut a plate, the interior edge of the “C” channel, where the cut was made, should be de-burred. This will protect the tubing from sharp edges. • ThermoFin plates are typically placed 8 inches on center or 6 inches on center under the sub-floor in the joist bays. Remove • any nails in the sub-floor that would interfere with the plate fitting flat and tight to the wood. • Attach the ThermoFin with self-drilling screws placed 12 inches to 18 inches apart down both sides of the “C” channel along the scoring marks that are extruded into the ThermoFin. The length of the screw should be selected to prevent penetrating the topside of the subfloor. • The ThermoFin provides a rigid, flat surface that can be tightly pressed against the floor to facilitate heat transfer. • A short piece of PEX tubing can be snapped into the adjoining “C” channels in order to ensure alignment. Allow a one inch gap between the ends of the plates. • If there are obstructions in the axis that the ThermoFin is running, the ThermoFin can be stopped short of the obstruction and continued on the other side. • The PEX tubing that snaps into the ThermoFin is flexible and can be routed around most obstructions. • The ThermoFin can be installed to the outside edge of the joist bays near the rim joist to increase heat transfer to the edge of the exterior walls. • The PEX tubing can be “dropped” out of the “C” channel before the end of the ThermoFin to make the bend through the joist. • After all the ThermoFin is installed, the holes in the joists should be drilled. All holes in joists should be drilled prior to running the tubing. • The typical diameter of the hole is 1 3/8” regardless of the pipe size. It is important that the joist holes line up well. • A plastic isolator, commonly used in plumbing and heating installations, should be placed in each joist hole that the PEX tubing runs through. • Isolators are especially important in long runs through several consecutive joists. The isolators protect the PEX tube and help to eliminate any potential noise from expansion and contraction. • The PEX tubing must be pulled through all of the holes and around • any obstructions before it is snapped into the ThermoFin. • Connect the PEX tube end to one side of the manifold set and start • inserting the tubing in the ThermoFin at the end of the loop. A rubber mallet or air driven palm hammer is required to press the tubing into the ThermoFin. • Work continuously to the opposite end of the loop and connect it to the other side of the manifold set. Do not cut the PEX tubing until it has all been inserted into the ThermoFin. • It is highly recommended the installer follow a detailed layout map (provided by Radiant Engineering for our system designs) where zoning and flow balancing has already been addressed. • In general, runs of 1/2 inch PEX tubing should not exceed 250 feet. The tubing should be pressurized with air to 50 p.s.i. 24 hours prior to covering. The tubing should not lose a significant • amount of air pressure during this time. • Radiant Design Supply, Inc. formerly Radiant Engineering • copyright 2015 Radiant Engineering Inc • Bozeman, Montana USA • http://www.radiantdesignandsupply.com
