Interesting idea...or suicide! Heating dump valve.
While trying to figure out ways to keep the waste valve assemblies above freezing, I had sort of a neat idea...or is it.
With the furnace running, the exhaust on the outside of the trailer throws out a lot of heat. Seems sort of wasteful. I had this idea that I could take a length of aluminum drier duct and without attaching that right on the trailer, which I know would be dangerous, position duct a few inches away from furnace exhaust and then have the opposite end pointing at the valve assembly.
Obviously by the time the heat makes it to the end of the aluminum duct, the temperature would be greatly diminished, but I figured it would just need to blow out air that is above 32 degrees.
Thought I see what you guys think.
Sometimes I wish I were living in the stone age. Then I would know I'm the smartest person in the world.
