Propane RV furnaces with ducts are common. Cold air return is available, but less common.

The Espar/Webasto type heater can be VERY load outside. These heaters are common on boats in the PNW. The worst of them will keep the whole anchorage awake at night. The best sound about like a propane RV furnace. It depends somewhat on the installation, manufacturers offer mufflers for the exhaust.


ya if some one doesnt use the mufflers, with two stacked straight through mufflers they are only 52 decibels and that was on a 5K unit, I bet my propain furnace in the 5th wheel is in the mid 60's.

I have run both. Both have good and bad features, but I am leaning towards my Espar being better then the RV furnaces that I had. Now my Espar is located in my van so this will change a few things then a truck camper.

One of the GREAT benefits is the ability to run multiple ducts BUT even bigger for me is having a cold air return. I can take cold air from the coldest part of my vehicle and heat it. My RV furnaces all took air from the front of the furnace to heat and with them being a foot or two from the floor the floor was always cooler. Maybe other units had this ability but my two units did not.

I like that my Espar uses gas as it stays liquid in extreme cold better then the propane. I like only having one fuel to worry about in my van. Using one of the diesel units with separate fuel tank would work but I would be back to two fuels to make sure were topped up.

Inside noise I would say is a little quieter then the propane. Maybe half the noise on my worst RV propane unit and a quarter on the less noisy one I had in my RV.

BIG issue is the noise on the outside. The Epsar is like a CF-18 kicking in the afterburners when it fires. Does keep people from camping on that side of me. Maybe an issue if you run it in a campground.

Myself I would not put a duct in the cab over. Heat rises and it would get REALLY toasty up there.

A second thought would be a vented cat heater if you are looking for quiet.


stack two mufflers, the strait type not the offset and it cuts the outside noise down to the low 50's which is way quieter than any propain furnace I have had.

Cat heater is out of the question, I want combustion air to be totaly seperat from the heating air. there is a reason they are not factory in rv's anymore pus with the dog and a grandkid I dont need singed hair or burnt fingers.
