Y'all seem to be assuming that this person is going to be spending a LOT of time in the bathroom... LOL.

That said, I've seen episodes of shows (on HGTV, if I remember right) where they installed much smaller EcoSmart fireplaces in bathrooms - under the assumption, one would assume, that they would not be on for very long. The size of the fuel source is small enough to limit that, I believe (at least on the couple I'm looking at for my house). I'm guessing those were more for ambiance than a heat source. The fireplace in on this page seems way out of proportion to the space - can't imagine someone actually having that in a bathroom on a regular basis. I'd bump in to it! And that would cause a whole slew of new problems.

A CO monitor/alarm is a good thing to have, too.

Good points Frank. Also Jabroney, if you re-read my post I didn't say it sucked the air out of the room I wrote that without a good source of fresh air this unit could be dangerous. If this unit has no chimney to the outside how could it remove the air from the space? If you are going to argue at least get your facts straight. Do you sell these units? Is this why you are so adamant about this? Or are you just someone who believes the laws of nature and physics don't apply to you. You asked for Franks credentials, I'll offer mine. I have a BS in Renewable Energy Sciences and an AAS in Renewable Energy Technology. Indoor air quality is an integral component in Passive and Active Solar Design. Please check out Franks' sources and educate yourself a bit.

My source being a degree in chemistry... I didn't say it "sucked the air out of the room". Basic chemistry - the fire creates carbon, the carbon reacts with oxygen, creating carbon dioxide - as long as there is enough air available. This reduces - by using up - the available oxygen. When the level of oxygen becomes low carbon will react with just one rather than two oxygen molecules, creating carbon monoxide instead. Sure, a drafty shack would delay this, but a good fire can still "eat" oxygen faster than a drafty shack can replace it from outdoors. Remember that the draft is lessened due to the air pressure differences and temperature differences.

But sure, I am not a credible source. I can understand why you take a needlessly hostile and aggressive and somewhat less thought through approach to my statements... So rather than to lower myself to your level and keep arguing about this, I'll leave you with some facts from other sources.

200 americans die each year from this sort of thing, as reported by CPSC Document #5010 which you can find here: http://www.cpsc.gov/CPSCPUB/PUBS/5010.html

Carbon monoxide itself contributes to about 5613 deaths each year in America as reported by this report: http://jama.ama-assn.org/cgi/content/abstract/266/5/659

Or you can read Goldfrank's toxicologic emergencies, ISBN 0-07-136001-8, that also talks about how a semi-enclosed building is more than enough to die from carbon monoxide poisioning with an indoor heater...

Enough of my time wasted, bye bye.

Really, Frank? What's your source? My point was the previos poster's claim that this fire would suck all the air out of the room - not the CO build-up

Doesn't need to be airtight, Jabroney. There is a lot of people who die every year because they put fires indoors, even in a drafty shack the concentration of gas can build up to deadly levels by something as simple as the air pressure difference between the building and the outside. A small gap here and there would not save your life if you put this thing in there - an open door or window would be needed. Or a chimney.

Are you clowns for real? who has ever heard of an airtight bathroom?

Like the previous poster said this is pretty much a suicide device. Burning ethanol creates carbon dioxide and water - if you keep burning it in an enclosed space you will create carbon monoxide due to lack of oxygen. Lack of oxygen means... death.

Burning ethanol might be clean, but it is no more healthy than burning wood.

I'm sorry that should have read Carbon Monoxide instead of Carbon Dioxide.

Very pretty. Please remember that any combustion inside a house creates Carbon Dioxide (CO), whether it is wood, charcoal, ethanol, candles, etc. This unit inside a small enclosed place, such as a lavatory, without a good outside air source could be dangerous.
