Aha! I found it. An Atwood Excalibur. I’m going to look into it. Thanks.

Please elaborate.

Was a functional CO detector present?

Sadly, there are a lot of macho men on this forum that take the unnecessary risks in order to save a couple of bucks in propane that believe it won't happen to them.


There are also a lot of men and women who understand how unvented catalytic heaters work, and how to use them safely.


And you are willing to apply for a Darwin Award on the basis of a 25 cent sensor? No Thanks! When is the last time the sensor was tested?

BTW I won't run a generator while sleeping either--which is why I want a high capacity battery bank using SiO2 batteries.

The situation was a chimney blockage in a gas fireplace in London, UK. I doubt there was a monitor--but my daughter knew the symptoms, and left the house.

Oops, I just notuced that Atwood was sold to Dometic (ugg…) and they no longer make the 2 speed furnace - my guess, probably because it met customer’s needs in a good way…Either way, my camper came with a 30k btu Suburban (waaaay oversized) and it turned out that the Atwood when in low mode (15k btu) does a far better job with much less noise while saving a bunch of energy and reducing nagging interior drafts.

Well it does seem the two stage Atwood units are no more. I can’t find them anywhere. Everyone says no longer available or sold out.

Hi,
The platinum cat vented catalytic heater is yards more efficient.


I'm not even sure they're selling those any more.

There is a website, but it doesn't have any info on where to actually buy one.

ETA: Apparently, someone is still selling them on a built-to-order basis.

Camco and Mr. Heater make unvented catalytic heaters that are readily available - and they are even more efficient than their vented counterparts. They don't require any electricity, so there is no drain on your house batteries while dry-camped.

I use the Camco 3000 BTU model in my little 17-footer, and like it immensely.

Well, since you live down south you might just consider a smaller more efficient furnace - trust that I have no regrets about downsizing, even when in the snow…Check for operating amps…

Maybe I missed it, but are you doing "full time" RVing? If so, then investing in a better heating source might be best??

I have a 2019 Rockwood TT and it has the same type of propane heater that my family had in our 1977 Taurus TT... The only difference was we had to light a pilot light and keep it going on the old Taurus. The new rigs are all that auto spark deal. Same the the water heater... Same basic unit, but still just blows a huge flame into a chamber and it heats what it heats... [emoticon]

I'm only a fair weather camper, so basically between May and Sept... It does get a bit chilly at night at times, and if the little portable electric heater can't keep up, I'll turn on the RV furnace and that does really keep the rig warm... It's just loud and probably does use a lot of propane.. So does the water heater, but my new TT has a 120v heater as long as i'm plugged in, so I use that for hot water...

Anyway, I'm sure there are a lot of more efficient heating options out there, and to fit into an older rig is just making it fit and work I would think..

Good luck in the end and stay warm! [emoticon]

I would only add that if your present furnace tends to cycle on and off all too frequently, then from my own experience it suggest you too need a smaller unit…

I don't fulltime but I like to camp offgrid whenever I can. My furnace seems to be properly sized. When its cold out (20 degrees) it will run maybe 60% 0f the time. The coldest I've been is around zero and that ran 85 to 90% of the time. Looks like I need to live with it.
