Here in south carolina, we really havent had much cold here so far but there have been some nights that were about 35-39 degrees. We have had about 4 of those nights , and some nights where it was in the 40's. When it's that cold and I come into the cave, my little 1500W patton electric heater does just good enough for me to put it near my feet and keep me fairly warm so I could get on the computer and stuff. I also have on good clothing also so that helps. I do want in there to be comfortable enough to watch a movie when I want to and might have some guests over sometime and want people to be comfy. The cave is an 18X21 and 378 sq ft. As long as its 50 degrees or better, I really don't even need this small heater on.

I have been looking at some nice forced air kerosene heaters online and want something just to be able to heat in here decent or bring the temp up from say one of those 35 degree nights or days and then turn it on low or off and let the small electric one keep it warm some at least. Will it be safe as far as fumes and stuff in here? I do have a vent about the garage door, a window, and there are plenty of drafts where air can come in and go out so there is plenty of ventilation. It won't run all the time I'm in here anyway and if I'm just checking email and stuff on the pc, I usually dont be in here no more than 2 hrs and usually the electric heater is fine for that. If I'm watching a movie, the most I would be in is about 4 hrs or so. I will provide a pic or link to one below. Probably won't be one that big though as far as btu's.

Also, I might not even get a new one since I won't use it that much. Then again, I might wana get one that size since my new 24X41 is 984 sq ft and if I'm ever doing any work in it or cleaning or waxing my car I could take the heater in there. I pretty much want to do something inexpensive instead of spending $330 bucks before taxes on a through wall AC/heat piece. I like the idea of having a large air master 30-40 inch fan to where I can in the summer put up the garage door and open the rear door of the cave and let it blow that air through. Or I can leave doors closed and open the window and let that fan go to work. I like the idea of the kerosene forced air and Air master fan vs the through wall unit. Actually pricing might be not too much less but at least with the kerosene and air master I can actually have the doors open if i wanted to and still get good heat and air.

My shop is 24x30 i use a 40,000 btu propane forced heater because i didn't want to smell kerosene or diesel fumes. But you won't be able to watch a movie with it running there so loud you can't hear yourself think. :thThumbsU

I have been in heating for 40 years and if you want to stay around for a while, then don't try to heat that small of space with a Kerosene heater.

so as far as inhaling fumes if you dosed off, with propane is it safe in that regard? Also can the propane tank be inside?

I agree with paul, I would not put any type of heating source, that uses fossil fuel, in any space where it will be occupied by myself,family or friends unless it is properly vented. Un unvented heater releases carbon monoxide and moisture into the air. You only need 12,700 btus to heat that area basing that you have an 8' ceiling and it is 2"X4" construction with insulation. Think this out and look fo a good used vented space heater or vented wall heater. Good Luck.

Yes the tank is inside you get about 6ft of hose with the heater. Like stated have some ventilation. I hope next year to get a ceiling mount vented heater

so is there any safety issues with propane inside as far as does it give off carbon monoxide? And My cave is vented. Its not by any means perfectly closed and every crack sealed lol. Plus the vent above garage door. Also a window and a rear door as well that can open if i needed to

I almost croaked using a propane camping heater in a small room in my garage,the kind that has a metal pie pan shaped reflector...fell asleep watching TV,and was lucky I woke up when I did...the room is by no means air tight either!.....any heater that burns something creates carbon monoxide...the torpedo kerosene heaters are not good either,I have a 50K and 110K btu pair I use in the larger area of the garage,but the stink they make will nauseate me very quickly,and can suffocate you in a short time in an enclosed area..they are noisy too,something to consider if your trying to watch TV or listen to a radio....every time I use one I get dizzy and nauseous...a wood fire is not as deadly as fossil fuel can be,but is still plenty dangerous if you let enough smoke build up inside...

Electric heat is expensive as heck,but is probably the safest...I know a guy who used a clothes dryer for a heat source in a small "office" room that worked good,but was costly to operate--forced hot air heat is dry and can lead to sinus problems and frequent colds.....another guy I know rigged up a hot water heater to baseboard heater radiators (an electric one) and has been pleased with it....he put some anti-freeze in the system so it dont have to be left on constantly to avoid freezing problems...

People heat with LP ventless all the time--I have one in the living room for a backup.Never hurt us?If they were killers,wouldn't got one.In my shop I use wood heater,like they've had on the market for humpteen years.On real cold days I start up my keo.const.heater (with door part open)to knock off chill while the wood heater heats up.Don't like the keo.types in my house,they do smell a tad and sound like a freight train:trink40:

I've been using a Propane heater for my 12 X 24 for a few years now, I added a tarp to close the space to 12 X 12 on really cold days (32 or less) not often. Works well, Shop is NOT air tight (the tarp moves)
But I am warm (66 deg right now Outside 48.) Heater is on the LO setting.

just get a regular kerosun model, not a forced air. when properly adjusted they don't stink, at least to me. and they are designed for indoor use.
I have a 30 year old Kerosun 8500 btu kerosene heater. It probably needs a new wick, and a good cleaning. There is a brief smell when you first light it, and then again when you shut it down. Otherwise, it burns clean, scent free, silently, and fills a 12x24 sunroom with plenty of heat for a comfortable work environment. In October when I lost electric for several days after the snow storm I set it in my entrance way and kept my whole first floor at about 60° through the night. Not exactly toasty, but fine for us hearty PA folks.

i was just about to ask if the regular kerosene ones and the forced air were the same cause we used the regular ones in our home growing up and we are still here lol.

I really will think about the kerosene forced air just having it to mainly heat up the cave right away and when it is up to a nice temp say even from 35 to about 50, i can turn it off and just use the electric. If it drops back down too much over course of watching a movie, i will turn it back on for maybe 10-15 mins then back off. That's why I dont want to really get a new one but if i get a used one I want to make sure its in good shape and not an unsafe one from someone who was trying to get rid of it for some reason ( like if i were to get from a pond shop).

Another reason I was considering the forced air kero is for my 24x41, I have 3 garage doors and 2 windows and if I'm ever doing anything in there and needed to warm up, that should be perfect for that building. It's just a 4 car garage and not a workshop or anything but if i want to do something in there I can and be out of the weather.

These questions seem to come up annually.

My experience with a 19,500 BTU/hr tradtional kerosene heater, with more than quadruple the recommended 1 sq/in per 1,000 BTU ventilation (36 inch wide window open 6 inches). 19x26 garage, smoke detector, CO detector. After 6 hours of use I had a splitting headache. Verdict? Low oxygen. Just as deadly as CO.

Wear a Carhart, and use an electric space heater with a fan to keep your hands and immediate work area clear.

Oh, and BTW, a kerosene heater will emit CO if the wick is fouled or improperly adjusted - read the manual if you don't believe me.

I have a 20 inch windchill fan from walmart that blows crazy air, I will have that fan in there blowing and have the heater right near the garage door, maybe even have the window up, plus the vent I have above the garage door so ventilation should be good to go. Also, I cant see that heater running for more than 30 mins at the most at a time, maybe an hr because i wont need it to keep running constantly. I will have the electric one on as well, upfront near the couch area and where my pc is, so that will keep it decent while the forced air is off.

I would stay away from the bullet heater, while they do a great job on heating the fumes they give off are pretty nasty.

In my 30x30 I had a heater simular to this one, but mine had an electric blower & an exhaust vent that you could run outside. it had an internal tank & also a fitting where you could run a tank from outside.

Its something that I suggest you look into.
