Camper furnace evolution over years

[John Linck]

I was told by Scamp sales folks that their furnaces are quieter these days than years ago. Has the industry evolved to be more sensitive to noise? Or has Scamp moved to a quieter model? My last Scamp was a 1991 and noisy.


Seems furnaces are too big (btu output) for little trailers and way too noisy. Back in 1974 I had a small, simple, gravity furnace that cost $75.00 and was dead silent, worked without electricity, maintained an even temperature in my small camper and had a sealed externally vented combustion chamber. Don't remember the brand but it would be perfect in a small trailer today.

I expect technology to evolve in a good way. My iphone makes my Commodore 64 feel like a handful of counting stones. Seems furnaces have regressed. The only modern innovation I like is the flame-out gas cutoff valve. Wouldn't be surprised if my old furnace had that too.

Best Autumn to you all, john the toymaker

just replaced my suburban with a attwood 8012 II (Squirrel cage fan in attwood ) 75% quieter than suburban prop fan. See suburban has a new NT-Q series out (suppose Q is for quiet) dont have any experience with them

Escape installs Atwood 8012's in all their trailers, 15/17/19/21/5th wheel

The Atwood 8012 is the smallest "size" which is readily available - the "12" means 12,000 BTU/hour of heat input rate. It is quieter than the 7912 (and consumes less electrical power) because it has a lower-power fan, which it can get away with because - unlike all the other models - it can't be used in a ducted system. Perhaps Scamp changed from the 7912 to the 8012?

I think what has happened to furnace selection is that RVs have grown in size and the smallest units are being forgotten by the industry.
