In order to make the new L shape heat register work and connect to the same locations where the pipes enter the room, the pipe had to double back on itself. This is SunTemp brand, and they have hangers built in to support the return line above the heat fins. To save cost, I re-used the sections of heat register that were behind the TV and on either side of the fireplace to make a new length of register that you can see against the far wall. The result is that there is enough register for the size of the room, and it is all hidden behind the sectional. The register housings were all removed and spray painted with Rustolium Epoxy Paint (appliance paint) to give a fresh look and hard durable finish. The register housings were re-installed with screws rather than nails that pull loose that the builder used.
