1 870 and 1 932 pounds the panels are then transported to the installation site on standard shipping pallets the number of panels on a pallet and resulting weight of a pallet can be readily varied depending on transportation abilities the area in which the radiant heat system is being installed is provided with an under layer 29 as shown in fig2 under layer 29 may be a plywood subfloor in other situations as shown in fig2 and 21 it may be a concrete subfloor under layer 29 is leveled with any imperfections in the subfloor filled with an epoxy or other appropriate filler and swept clean the length of conduit 21 needed for given area 44 is determined based on the area dimensions and anticipated conduit routing the appropriate number and types of panels are transported to the installation site the number of panels required is based on the square footage of the subject area and the dimensions of the panels to be used the types of panels used will depend on the channel configurations which are most appropriate for the predetermined routing of conduit 21 also the dimensions of channel 20 must be appropriate for the size and dimensions of conduit 21 being used as shown in fig1 different types of panels and channel configurations may be used depending on the desired routing of the conduit through the subject area because of the small size.
