Little Buddy Heaters

Postby schenier » Mon Jan 25, 2016 10:18 pm

Hello,

We're in the middle of our build and I realize now that a heater without shore power is just not feasible. That being said, has anyone used a little buddy heater in their TD? I was thinking of mounting a CO2 detector as well, but well frankly, I'm scared of killing us all in our sleep. We are planning to use the TD to go skiing. There will be 3 of us in there. How warm do you stay with just bodies and good sleeping bags?

A sleeping adult human produces about 250 BTU/hour. That's equal to about 73 watts of electrical heating per hour. At rest but awake about 400 BTU/hour.

I really don't like non vented fuel consuming heaters and the smaller the space the more I dislike them. Too much potential danger for my liking.

I use one to take the chill off a cold garage but I don't use it once I'm out in the garage.

Never ever use a unvented heater in a TD!!! Some boys in MN just DIED using a unvented heater in a fish house.
I can up with a propane radiant tube and a propane radiant dog dish heater that is fully vented.

The tube does not have the reflector behind it in the picture.
I try to make it easy to build. The dog dish heater does work better in that it drafts better.138445116155116153116475

Any combustion source inside a teardrop strikes me as just a really bad idea!

There are a number of potential solutions most not inexpensive.
I have an Espar diesel heater as does one other member 7819378194

Since we have a water heater I have installed a bypass through an automotive heater core using a solar hot water pump and computer case fan. My idea but a couple of folks beat me to trying it out.

An external boiler could also be used with this set up using what ever heat source, real caution would need to be exercised in keeping it from getting too hot or a boiler explosion (you do not want a sealed system).
This could be the least expensive and if you want to pursue this idea I have been thinking about how to do it safely and we can discuss it.

Both very cool ideas Shadow Catcher and Kenneth, I'll spend some time looking into that. I love that it is designed specifically for the dog. I don't think I could sleep, even after turning off a non vented heat source. Like you all said, just too much potential. I may still get one for the galley because making my coffee in the snow will make me cranky. The heater is designed for tents and was recommended by an ice climbing friend, but it still makes me super uneasy.

The insulation we are using is R9, which seems low compared to a house obviously, but it's quite through.

One of our favorite ski spots gives free campsites (with electric) during the winter. I'm thinking the best course of action is to try it out there, bringing a small ceramic heater as a back up, but see if it's comfortable enough without it. Most places are not so generous. My main concern is the 5 year old, I think us two grown people would be fine.

I am thinking that a buddy heater could be used with the dog dish style heater with the buddy outside on a shelve, pointed into the dog dish with wind screen around it. Not the most efficient but safe!!

We have used our Little Buddy in our tent when the temp hit 5 degrees F. We only use it for a few minutes before we go to sleep and after we wake up. Five minutes max.
We make sure the tent is properly vented and have tested the oxygen sensor regularly to make sure it is working.

We have purchased a small 12v ceramic heater to use in the TD, but will use it as above- sparingly.
Pile on the covers (we use two 0 degree sleeping bags zipped together and a fleece sleep sack in the tent) and you will be fine.

the atwood rv propane furnace or any rv appoved furnace s the way to go............ most are around 400 new and a lot less used..........the rv industry standard and recombined thing to heat any type of camper or motor home your teardrops no different. they are co2 fully safe and fully vented its why they are standard on modern rvs.................if you heat with a buddy portable cermanic they do have a low oxygen shut off but in snow and deep cold you want heat all night and they cant be run all night only before bedtime.............
also with a portable cermanic heater they are just for pre heating before bed. don't leave on on all night long...........also tip over fire danger with them too.
the deisle heaters are nice but way pricy they start out on ebay at like 10000 bucks 8 or 900 to 1500 a pop...............


I use a road pro trucker 12 volt heater and 12 volt electric blanket inside a army mummy bag here in Wyoming...........but its only for summer time camping..

just a sleeping bag and lots of clothes and blankets is okay for summer not when the temps drop below 22 here in Wyoming in late sept. not at all when your skiing or in snow............


if you got a 120 hook up just get a tiney 1000 watt heater form wally world they will run you out of a teardrop. and are cheap..........no 120 I highly recombined a on board normal rv industry standared propane forced air furnace...................rvs even old ones all have them for a reason...........and fairly affordable to the desil one..





the rest is stuff I don't recomind and am not sure they will work or are reliable..... I am myself not into these ideas........but its just me and my opeions and your all free to disagera. with me............its your world and not mine and I am not starting any squalbes. I have a full right to my 2 cents this post is all just my personal opeions after 5 yeasrs camping in my own teardrop in Wyoming what works for me may be over kills for a guy in texas. again I am not here to start world war 3 this is just what I like to do...........slow

if I were you and I wanted to be safe and no co2 and wanted something to heat the tear I would not compermize and would do it right..........being cold is no fun in northern cold climates..............and sleeping bags and -minus 40 below bags are for summer time........you got a set of wood walls and a good matteress a back packer cant take on his back ..................its a advantage why not do it right..........

slow..........just my 2 cents after 5 years in my own teardrop.

a trip to a junk yard cant net you a rv forced air propae furnace for lie 200 or less in working shape sometimes you can snag a junker rv for like 100 bucks and get lucky and get a used on to tear out for penneys. ebay can cut them down from 400 to 200 in fairly good used condition..............slow

I do this rowret all summer long its works its cheap..........but when you talking snow and temps in the teens it doest put enough heat out.......that's the problem...........most of them like I got are only 300 watts they beat a dash heator from wally world but they are still to small for winter time..............they are summer time heaters.............and I got my tear wired in to my suvs battery so I can run it about half a hour than shut my suv off and go to bed. but then its just another 30 mins off that and your like down to 11 something or 50 percent on a deep cyle.............these 12 volt trucker heators I am not kidding and honest are battery hogs...........that's why I only leave them on a half a hour with out the suv running....................they are designed for a semi with huge batterys and more than one..............and no trucker is going to shut a semi off at a truck stop in the winter time...........so got a huge 24 volt high oupute altenater in that semi behind these heators...................again they work great for teardrops...........and no you cant run mine all night long in my teardrop..........ujust 30 mins when I shut my suvs engine off..............they are good for temps down to only 28 or 25..........22 is the most I have tested mine and it is in a overly insulated teardrop to..........like 2 inch foam insulation............
