Options for furnace replacement

As many of you know, I am currently having a new frame and subfloor installed in my 68 safari. When I was at the shop, I noticed that there was a large crack in my furnace that looked to be several years old.

I would like your opinions on something to replace the furnace. I do not anticipate a great deal of winter camping, but something for the chill in the early spring or mid fall would be nice.

What are my options? Electric baseboard heaters, wood burning like carlos ferguson, catalytic? Ease of use and installation would be a plus....perhaps I could just get a few ceramic heaters from walmart and use them instead!

Thanks....and good to be back on the forums.

Steve

I have used catalytic heaters as primary heat for several years. I don't camp in a location/time of year where I have to worry about water system freeze.

I'm currently looking for something for my '72 GT. It's smaller than my 25' Safari was and am looking at the Mr. Heater series. I would return to the catalytic idea, but I don't have a good safe surface to mount it on.

Catalytic would be my first choice in your scenario.

If anyone has experience with the Mr heater line I would appreciate your input. The "Big Buddy" seems that it may be the way to go for an extra$40 -$50 and double the heat of the smaller unit.

Dave

PS - I just ran across an older post of yours this AM, and was wondering how your project is going. ??

I fell while working on the tradewind and subsequently shredder the surgical repair that I had done in October. I will not be able to work on it so I am selling it. The local AS dealer offered me $2000 for it, but I am not that desperate yet.

Went to look at the coach in the shop and I am trying to figure how I am going to put humpty dumpty back together again.

Hi Dave,

I've been using the smaller Mr. Heater...

for years. I usually heat the trailer with the furnace and then maintain the temperature with the Mr. Heater. I don't like the furnace because of fan noise, battery drain and constant on-off cycling.

During my last outing at Tuolumne Meadows in Yosemite, the morning temperature was usually 23 degrees and we stay nice and toasty.

For the first time Winter camping in my 26' Airstream, we brought along a 1500 watt space heater on our trip to the 2007 Texas Vintage Rally last week to take the load off of our propane supply. With temps close to freezing on the first night, I don't think the furnace cycled. The next night, with temps at or below freezing (shore water line froze), the heater cycled on a couple of times. I think two 1500 watt space heaters would have probably kept the furnace off.

If this idea appeals to you, make sure you have two, 120 volt breakers available to support the load.

Steve,
I'm sorry to hear about your fall. Those types of incidents affect us in so many unexpected ways. Good luck with the Safari. Keep posting...
Dave

Mark, thanks for the reply. That's the kind of specific experience that I'm looking for.
Anybody else want to chime in on small portable propane heaters?
I don't want to hijack the thread - These answers will help with the original question perhaps.
Dave

Tom,

My electrical has been completely removed, so I will have to start from scratch. I am hoping to find an electrical diagram somewhere ...especially since my unit didnt have a converter or battery when I bought it. I assume the ac power comes in directly to an ac distribution panel for the Air conditioner, dc converter, and the 110 outlets. A question scince I am not too electrical saavy. If I have my 30 Amps coming in, will it just evenly distribute between the two breakers? Anyone know where a good diagram is?

I get worried about not having some kind of heater that runs off LPG. In a rare case that I may boon dock, or have to make an emergency pitstop it would be important to have heat.

Keep those thoughts coming.

Dangerous?

Are there issues with asphixiation and using these small portable units?

Not the ones shown in the post (#4) above. They are designed for interior use and have a low O2 shut-off in case there were a problem. They emit no CO. (Carbon Monoxide) Crack a window for ventilation.
Catalytics also need to have some ventilation due to O2 consumtion, but also produce no CO.

the "mr. Heater" IS a catalytic heater. hence the identical attributes...

cool thing about it is that you could use it somewhere other than your trailer...like, in case of a power failure at the house, or whatever.

I think I read that you can also buy an accessory connection for it that will allow you to use the propane supply in your trailer, rather than the small bottles of propane...which may not last all night long on a cold night.

Yes, there is a connector for a larger bottle available, it's extra.

I wasn't sure how they define catalytic. My old one had the mat "burn surface", the Mr. Heater is ceramic.

This image from my '67 owner's manual probably covers your '68:

even if it isn't a fabric "mat", there must be a platinum catalyst in there somewhere; this is what makes the chemical reaction that allows combustion without CO.
