Catalytic Space Heaters

Even in Alaska, it gets chilly during rainy days in the Summer, so my wife says. While camping out on the Kenai River, we/I was forced run my Honda 2k Generator a lot during the cool days and evenings, in order to use the Space Heater. Lot's of gas and noise.
We traveled during the month of September to Montana and came back to Alaska the first week of October. With my 26 ft uninsulated Keystone fifth wheeler, it did get cool and uncomfortable at night, when we spent an evening along the roadside pull out.
Looking at Pro's and Con's of a Catalytic Space Heater that would not draw any Electric, while pulled over for a night.
Any input would be appreciated.

I used a catalytic heater for years and they worked good. the problem I found with catalytics was that the pad collect dust and there is not a good way to clean them. When this happens they don't put out as good. I have gone to the blue flame heater. They seem to work better and are easy to keep clean. Both are non vented heater but we normally keep a vent open and I am confortable with them. I would suggest looking at the blue flame before you buy.

I forgot to add you should get one with a thermstat,they are easier on gas. WE leave for a short time we feel safe leaving it on a low setting. We don't often leave a heater on at night but when one of us is puny or it is extra cold we have left it on low at night.

We use a WAVE 8 catalytic heater when boondocking. I have the gas plumbed into the rig with a quick disconnect then use a 8' gas hose. We call this heater our "fireplace", as it puts out a lot of heat. We can move it around and point it at us. We use a pillow case to keep it covered when not in use to keep the dust out. But I've also heard good things about the Blue Flame heater.

Here's another option for you. We have used a "2-brick" Vanguard ceramic heater for 4 years and would not be without one. I plumbed a "T" into the gas line running to our range top with a hard shut-off underneath, and a quick-disconnect sticking out the front of the cabinet. When not being used, the heater rides behind a chair, out of the way. Propane use is minimal.

When we first bought the heater, we were in a 31' class A and had to run it on a very low setting because it would just put out too much heat! We're now in a 40' class A and it still does the job very well. A 3-brick heater would be overkill unless you really like things hot!

One big advantage of the ceramics over the catalytics is that there are no issues with dust. The Vanguard is made in USA so if parts are ever an issue, you can supposedly go to Ace - the Chinese copy has metric parts??? (Do not know this for a fact, just passing on hearsay here.)

We picked ours up in Quartzsite during the 'season' at 'Grandma's Heaters', which is now located on the Hwy north of Main St., near the Pit Stop.

I also have a 3 brick ceramic I used in my 34 ft hithc hiker, now have it in a 12 by 14 shed. I agree Idon't really need a 3, on real cold morning I wput on 3 to knock the chill off and turn iback down to 1 or 2. My 3 brick would not work at 7000 ft, worked grea on one or 2.
