Heat ducting

[snowmanx]

Just installed an Atwood 34000btu in the enclosed, would like to use white PVC tubing for ducting...

What are the pros and cons....will any pvc do?


Thanks for any input.

I used single wall 4" white pvc in my trailer. I don't know if double wall would be any better or not, it is more costly and heavier.

My understanding of the use of PVC for ducting, it causes the potential for pretty severe static electricity. I think you need to ground it somehow. I have heard of people running a length of wire (copper probably) down the tube and grounding it to keep the PVC from getting charged up.

I used 4" white sewer pipe in my first trailer. I am is the process of doing the same thing again. It will all be sewer pipe but the boot dryer. The sewer pipe is way lighter then schedule 40. Finding white sewer pipe is the hard part. Most Box stores only have green. I get mine at ace hardware.

Your making this sheet metal worker cringe.... Whats wrong with 4" metal pipe?

I know sheet metal is a better but PVC just makes for a little more eye appeal.

used pvc and metal ducting in 5 trailers now. had good luck with all of them. best setup I found for getting trailer to really heat up is to run a single run in top corner of trailer from where heater is to back of trailer. half way down trailer run a t and run half way down wall, continue the main line to back of trailer with an elbow and run it down to foot above floor. heat rises. this get's ma trailers warmer then a whore in church.

Used black abs pipe for my ducts and boot dryer, if I remember right it's rated for hotter temps than white PVC and black looks better too.

Here is what I did.

I used the PVC pipe with a aluminum dryer vent hose to connect to the heater. The down tubes are rain gutter spouts so the hot air will make it to the floor and dry the floor and sleds out. I ended up adding 1 inch holes in the large pipe to keep the heater from tripping out due to high heat.

I found down sizing the shorter runs to 3" pipe helped increase the flow to to longer runs I also ran down the wall at rear as heat rises real quick
