Rainier70, How does the buddy heater create or put in moisture. It think the temperature differential the heater causes just condensate what is there? Am I thinking of this incorrect ?

Maybe because you have to leave a window cracked open and it draws moist air from outside?

this is a 12 volt dehumidifier. Would this help?

Isn't H2o a by-product of burning propane? Along with CO & CO2? Also, as O2 is consumed, more comes in to replace it, bringing in more H2O in the form of vapour?

I just Googled it. Burning propane does produce some water. I learn something new every day.

Is it true that one molecule of propane has about 4 of H20? My chemistry skills are seriously poor.


The condensation physics would be the same... just more humidity to condensate now I suppose.

McDave, did you have to Google the song?

Yes burning propane does increase water vapor. So does breathing. That 12 volt dehumidifier must draw a lot of juice. My home dehumidifier can almost double my electric bill. I shut it off after I got my bill!
I wonder how those granules in a plastic tub work.

All a dehumidifier is just an air conditioner that blows the room intake air through the evaporator coils and then back over the condenser coils to make it a close zero sum game from a temperature output perspective, yet you get the condensation on the evaporator coils to pull out humidity. An AC is also a dehumidifier... it is just that the cooled air is returned to the room and the condenser coils are cooled from outside air and returned outside.

If the concern is condensation, then insulation is needed. Not much you can do about the humidity unless you want to run the generator and use electric heat or a gas furnace that exhausts outside.

[Padilen]

Yes, I know AC's and dehumidifier's both remove moisture.
I do want a solar panel, inverter and a generator that's smaller and quieter than the 2 old ones I have. But money isn't available for those.
I'm wondering if my "bathroom" computer fan will remove moisture from showering. And if it will help when using the mister buddy. I'm going to be test camping soon and try it.

I'd think the fan you installed will at least remove some of the moisture (steam), but it has to get air from somewhere to push outside, so it will be pulling outside air in to maintain the pressure.

I really wouldn't need to have one where I live, but I have seen these really compact, wall mounted , wood burning (pellets) stoves that seem to work really well. I believe they even draw the air from outside so you are just left with a dry radiant heat that does not introduce CO2 or decrease ambient oxygen in the trailer. If I lived in a cold place, I'd seriously look at one of those.

[Rainier70]

Yes, burning propane does release water vapor.
It shouldn't be too serious of a problem if you use good ventilation and insulation. It is just another factor to keep in mind. In high humidity areas it can be more of an issue that in the drier west etc.
Good insulation helps with preventing condensation on surfaces like the ceiling. I have seen uninsulated ceilings "rain" with a propane heater....nasty!

You shouldn't have any problem on walls and ceiling, but you will still get some on your windows.

[Tommy B]

Oh YES It can get so bad I have to towel off the ceiling so it doesn't RAIN on me if I bump the C.T.

I Can still access my bare aluminum ceiling for the most part and may insulate that next summer when funds are available.

I will utilize the maxair fan vent and door window to vent the moisture. I did not have that before. Although it will let in cold air some It may help some. Ill just crank up the heat, vent, and find a happy medium for now.

Great thread. Learned a lot.

[McDave]

Any place where the warm air and cold air come together is prone to condensation. Heat "travels" in moisture. Cold air has less moisture and draws the moisture/heat from the warm air. The purpose of insulation/moist barriers is to keep the two air masses separate. If you insulate and seal the roof, you separate the warm/cold air masses and prevent/reduce the condensation. Also, since warm air is less dense it wants to rise, taking the moisture with it. Probably the most likely place for condensation would be the inner ceiling/roof.
In Montana, it's already cold enough to require some heat late night/early AM. When on shore power/gen. I have the
Coleman Mach III, it has a heatstrip and really is pretty effective since it moves a lot air at the roof/ceiling. I also found a catalytic type LP wall heater, but haven't installed or tested it. My plan would be to mount wall heater as per install instructions, and provide for a "fresh" vent below heater, and to vent exhaust out ceiling vent. Hopefully the heater will consume air from fresh vent, rather than cabin air, and exhaust hottest air (spent exhaust fumes) and thus allow radiant heat to warm cabin air without exchanging much cabin air. We'll see.
I don't have a lot of cubic feet to heat, 6'x6'x12'=432 cu ft, minus cabinets etc. and am well insulated and sealed so it shouldn't be that hard to heat and maintain, until it gets really cold.

McDave

This is the type of LP wall heater I have.

McDave, Howdy;

In my first RV/Home, I had a similar type of cat. heater as a back-up. I was living in
central Utah in a valley close to 6,000' elevation. Temps would dip into the minus
20 and 40 at times and I found that it worked very well. I sort of thought of it as a
Swamp Cooler for HEAT. Gotta have a place for the air to move to. It's
the creating the flow of air that makes a lot of the difference.

Hey I'm kicking you all out! !
It's Sort of my thread.
Nah it's great good info sharing.
I was looking at my posts on another form. I actually had stated that the portable AC I bought also had a dehumidify setting. It's amazing I have to read my posts to know what I was doing, and planning, almost 2 years ago.. . So before I had moisture I had a solution.

I've been told if I didn't over load I wouldn't know how to load. I have had 1 tons that I did so I try and take care with this 1/2 ton. I added air bags to help with sag. But yesterday I got this load of wood. It was to dark to get a pic. Of course I didn't think of it until after I got it unloaded.
.
Technically just over a face cord. But green and wet. We're I measure at with load on truck and 20 psi- not enough was 24&1/2 empty 30&1/2 20psi.
Also why oh why is my bed 6'3"
I had no place for my tool box after loading wood. So like any good hick

I had straps but 15' no short ones so my strap was the last of my roll of duct tape. Worked!

Finally was able to check the clearance for the kayak trailer wheels. If they will work to roll my CTC into pole barn.

It will be close, my floor Jack still had weight on it, it was stuck under axle. I'll have to remember not to place it there when I swap them on. I may have to lower the air pressure to squeeze it in. But it's going in that pole barn for winter.
