I have been trying to wrap my head around this fabrication and trust me, I really tried to appreciate what appeared to be a pretty cool project, however there is no place for this on our forum. This entire build is extremely dangerous and I will be locking this thread. I would also hope you have a great attorney, because the first person who gets injured or dies as a result of your informational video will undoubtedly sue the pants off of you.
Carbon monoxide is toxic (even deadly) at high levels and causes long-term health problems at low levels. Nitrogen dioxide, at even minute levels, may affect our immune systems and increase our susceptibility to respiratory infections. An oxygen depletion sensor (ODS) on unvented gas heaters and fireplaces shuts off the gas flow if the oxygen level drops below 18% (an indicator that not enough fresh air is getting into the house), but the ODS does not detect carbon monoxide or other hazardous emissions.
The second problem with venting combustion products indoors is that even the “clean” combustion products aren’t so good to introduce into our homes in large quantities. High levels of carbon dioxide make us feel drowsy and may cause eye irritation. Large quantities of water vapor released into our houses will raise the humidity level and can result in condensation on windows, concrete slabs, or areas of wall with “thermal bridges” through them. This moisture can result in mold growth, induce allergies and asthma among homeowners, and cause rot. The tighter the house, the greater the risk. A 30,000 Btu/hour unvented gas heater will produce about a third of a gallon of water per hour — about seven gallons per day if operated around the clock.
One should get an inkling that unvented gas heaters and fireplaces aren’t so good by reading the warning labels that come with them — suggesting that a window be opened during operation, that they not be operated for more than four hours at a time, and that they not be used as a primary heating system. Are those recommendations really going to be followed?
That unvented gas and kerosene appliances are a bad idea is no secret. A lot of scientists and health professionals have long argued that they don’t make sense. Our publication, Environmental Building News, and other publications such as Energy Design Update and Home Energy have argued for years that such appliances should, in fact, be banned by building codes.
