Making an rv furnace quieter
Every rv furnace we have ever had was noisy. Has anyone done something to quiet there furnace. I have considered trying to wrap the blower area in insulation. Anyone had any luck?

I'm not sure what the definition of 'loud' is for a furnace. Mine is fine. Electric space heaters are much louder, and annoying.

myredracer- I like your mod. I’d ask you how it’s done but then there might be a safety kerfuffle on the forum...
Forced air heat is like warming a rock with a hair dryer. It requires noise.
I boondock mostly. I use a Propane catalytic converter (Big Buddy) Not expensive, portable, quiet.
Requires some common sense “supplied by user.”
Here's a few pics. The one under the stove (Stelpro IIRC) was the exact width as the stove and all I had to do was remove a piece of wood between the stove and door below and it dropped right in. Each heater has it's own thermostat. The setup is just like in a house and is evenly heated throughout. The demand controller is under the dinette seating next to the converter/panel in the 4th pic and has a current sensing relay and the low voltage relays (24 VAC) for the t'stats. The bed & bath fans (King Pic-a-watt) are like in the last pic and you can see the squirrel cage fan. It has rubber vibration isolators which also helps. I ran all the wiring completely concealed in the ceiling and wall cavities. Looks like a factory install!
We never dry camp so this works well for us. Have never once tripped a 30 amp breaker. We're both hearing impaired and the TV is much easier to hear clearly without the furnace blasting away plus we sleep a lot better. Being an EE likely helped doing this mod... :)
