Harlin,
ok...after reading your post and going to the link. I now know what you are referring to as in "blue flame heater".
I have used one in the past, actually a couple years ago. no vent is needed at all. it's the same concept as a natural gas stove....just a larger scale, since is has a larger surface area that heats up. mine ran on liquid propane, and produced good heat. however the model i was using was quite old in the sense that all it had to regulate the heat was a knob that you turn similar to what you would find on a gas BBQ grill. if you wanted lower heat you turn the knob lower, if you wanted hotter the exact opposite.
the only negatives i saw was that you always needed to check on the gas/propane level...by lifting the tank as there's no visual read to tell you when the tank is out. maybe one could add an inline pressure gauge to check the level of the tank or if you had a natural gas heater you could run it to your existing gas line? it also produces a faint odor similar to that of a kerosene heater....and if you ever used one then you will know exactly what smell i am talking about. also there needed to be at least 3ft or more in front of the heater to prevent something from catching on fire.
the good side is that you don't need electric (not sure on the newer model that use a thermostat) you just hit the igniter and you got heat. it does put out quite a bit of humidity...i actually had to open the windows to air out the room as the windows would get all fogged up.
i wish i had a picture to post to show what mine looked at. it was a big box, and on the front it had the mesh layered with fiberglass.....very simple design, but worked.
it might be a good idea to invest in one as a back up heater just in case the power ever goes out....you could run one on low heat for several days before having to change out the tank, and that was with a turn knob model. so i would imagine one with a good thermostat would last even a week or so on low heat.....just enough heat to keep the animals safe until power gets turned back on.
hope that was helpful....just my experience & 2 cents,
Pitoon
>>Hey Mike,

>>I found some answers here. Although it would be nice to find answers from an unbiased source...(one that is not trying to sell anything)...this site was fairly informative. Perhaps they might be fine for the reptile quarters?

>>Looks like they are designed for indoor use in the living area as a supplemental heat source. (Like for that room that almost every home seems to have...the room that never seems as warm as all the others.)
>>Anyway here is a link.
