I came up with this simple way to stop wasting furnace heat in the bedroom of my 26BH. Why heat the bed area when it's not being used?
All it takes is a cardboard box to create a diverter that redirects the furnace output from the bedroom and into the main living area.
Check out the pics.
The first pic shows the unaltered furnace register. Second shows the cardboard box I used, with one end opened up. Third shows the box in place over the vent, directed towards the living area. Fourth shows diverted register with privacy curtain closed.
The bedroom area stays much cooler than the living area when I have this setup in place. It seems to make the furnace cycles shorter and less often. Good for battery and propane conservation!
Just to let you know, I modified my 26BH somewhat by removing the folding couch and the half-height wall that was behind it. So this won't work this way if yours is stock. But you might be able to figure out a different way to divert the heat.
I suppose you could just cover the register to close it off, but I'm not sure if it would take the engineered design out of spec and cause a safety issue, or possibly even damage the furnace.
