I have arthritis and cooler damp weather doesn't help it. My big thing about the catalytic is no battery power is needed so it would work as an emergency backup if you get caught somewhere with no way to keep power up. It also helps keep the thermostat at a lower setting by providing warmth in the area where I am sitting. FWIW if we the full custom route on our 80 I am seriously considering putting in a marine style fireplace

We have always used the stove top for heat when no power for fans on main unit.
Took off the black pot holders first.

I like the idea of a dedicated heater that uses no power though.

Portable Catalytic Heater

I just purchased a Paulin Tough PUP portable cat heater. I think they are fairly new. Maximum output is 8000 btu's. It's designed to be used indoors and has a low oxygen sensor that shuts the unit down if too much oxygen is consumed. It seems to be well made...steel construction. It will run off disposable propane cylinders or can use a standard adaptor for larger refillable cylinders.

I just tried it and it seems to work well. I think it will be a nice supplement to the furnace while boondocking, so I don't run the AS batteries down so quickly. The test will come over Thanksgiving when we boondock in Yosemite for 5 days with subfreezing nighttime temps.

I also bought an outdoor 14,000 btu unit that attaches to the top of a standard refillable propane cylinder. This will be nice for sitting around under the awning.

I spent 4 days bookdocking at the end of October, the weather was bad, with a rain/snow mix most of the time & temps in the lower 30's. (I know, what luck I have when choosing vacation time!) But my main furnace is dead and the catalytic kept us warm like a pro and didn't suck much propane. We stayed about 72 in the trailer with it on low the whole time. Amazing in how the same Airstreams you use to enjoy the great outdoors can help you forget about them too.

Are you specifically thinking of going during Thanksgiving, or would you like to hear about Yosemite in general? We go there every year, at different times, but never in summer as it gets to crowded. Spring and fall are best. We went for Thanksgiving for the first time last year and had a ball, even though it rained alot. It snows there too that time of year.

It's looks to be a stellar Thanksgiving weatherwise at Yosemite this year, Dave. I think I contributed to the nice weather by purchasing a new rain jacket, and (so nobody thinks this thread is hijacked), 2 CATALYTIC HEATERS! But, as with Sierra Nevada weather...the one thing you always know is..you never know.

The consensus is in. The PUP exceeded my expectations and woked great. I used it the entire time while in Yosemite. Nighttime temps were in the low 20's, and it kept the AS warm no problem. Even though I had a 12' hose to use with my 20lb refillable cylinder, I used disposable 1 lb cylinders the entire time. The reason is I purchased a $12.99 valve that allows you to refill the disposable cylinders from the 20lb cylinder. The refill process takes 1 minute per cylinder and fills it to about 75%.

Hi, sounds like a good time up there, such a beautiful valley.

So, how much was the PUP, how many disposible cylindars did you use, about how big is the catalytic area?

I was going to spring for the Olympic model, but if this (or something comparable) works in 20 degree temps, I may try it. Any further pros and cons or other brands you compared would be appreciated. My primary heater is beginning to have "issues" so I need to do something soon.
Thanks, Dave

Hi Dave,
They claim 2.8 hours on high (8000 btu) and 5.5 hours on low (4000 btu) mper 1 lb cylinder. I went through about 1 cylinder per day running it in the morning and evening so their claim sounds about right...no science here. I think the catalyst size is about 4- 6 inches square, but I didn't measure it, I'm just quoting from my feeble vacation ravaged memory. You can pick one up on line for less than $90 +shipping. The only other cat heater in this class is the Mr. Heater Buddy, which offers many of the same features.

My intent for using this was as a supplement to the AS propane furnace in order to save the batteries while boondocking. I think I ran the AS furnace for about 5-10 minutes the whole trip.

If you Google Paulin Pup, you can get more information.

Catalytic Safe?

Okay just read a arcticle where the writer say's he would never use a catalytic heater in an RV and now it has me worried as that is the only heat we have in ours. From what I have read one should open a vent one inch for every 1000 btu. Say roof vent open and a rear window open. Now I feel maybe I should just turn it off and use blankets through the night. What do yall do if using just a catalytic heater no furnace. Its finally gotten chilly here and we are going to Palmetto State Park in November. Just want to be safe.
thanks
James

James,
We returned last week from 8,500 miles from NC to Vancouver BC and back including Jackson, Yellowstone, Hill City SD, and two weeks in Ohio. We ran the Olympian Wave 6 for hanging around or reading, dining, and before showers. Ours spent this trip on the optional installed feet with a five foot flex hose. Zero problems and really comfortable.

We never sleep with catalytic heater on, nor with lit candles burning. Just not worth the potential risks. We always keep the window at one end open 1-3 inches and the roof vent at opposite end open a couple inches. Very comfortable, keeps the furnace off, warms you nicely.

A friend has had a Wave 4 in his AS 25 for years and says he wishes he had the Wave 6. Another friend has been thrilled with his Mr. Buddy catalytic for several years in his AS 34. We wouldn't swap for anything but decided on this recent nine-week odyssey we would take the feet off and mount the Wave 6 on hinges a few inches off the floor. Unclutters the doorway a little better and still allows directing the radiant heat where we sit.

One scare -- I smelled that "propane smell" one day pretty strong whenever I walked near the cabinet containing the gas piping. We'd been over some really rough pavement and maybe had jostled one of the flared tee joints too much. We were at an overnite stop in North Dakota and had stopped early that day. I retrieved several open-end wrenches, turned off the gas at the bottles, and proceeded to try and retighten all the flare fittings for the catalytic heater. I removed all the kitchen drawers to reach where I tee'd the new line in. I reached between the bottom of the oven and the top of the furnace to retighten the fittings at the new gas valve, and I retightened at the heater. Okay, everything is really tightened and ready for pressure. I leak tested thoroughly. No, no bubbles no leaks. Grab a brew and celebrate. Take a few deep gulps and enjoy another hacker repair saving the day.

But wait! I smell the damned gas perfume again, that nasty stuff they give the gas so you can smell it leaking. I go outside to clear my nose and head. Finish the beer -- priorities still straight. Go back in and sniff out the smell as carefully as I can -- I mean, I know the flared joints all tested tight. Rule out the oven cabinet and gas piping. Well, then what? Trace, with my not so great sniffer, and find the smell emanating from the cupboard upper section. Reach a store package, not very big, of a whole garlic clove. Yep, that's the smell. Good news, my gas piping is really tight. And, the garlic clove will live or die in the airtight tupperware. Next time we will just have to buy minced garlic in the glass jar.

The heater, used appropriately, is safe. You must ventilate the trailer while burning any unvented catalytic heater. You must adhere to the required clearance to combustibles, as for any heat source. A radiant heater is slow to warm your trailer but great at keeping you comfortable if it can shine on you. We love ours and would get another if we didn't have it.
