Safety

Homes experience lowered levels of oxygen all the time – from fans, candles, drafts, etc. – which causes incomplete combustion in a gas-fired unit. Incomplete combustion produces carbon monoxide…and without an exhaust system, it has nowhere to go but outward. Some owners claim these units are harmless because their CO detectors have never gone off, but they are actually only triggered by high CO levels…meaning that low or moderate levels fly under their radars.

Performance

It’s commonly said that ventless gas units are 100% efficient, and are thus the perfect heating solution. However, one fact is always left out: it is required by law to keep the windows open while burning them, even on the most bitter cold days…literally throwing any claims of efficiency out the window. They also cannot be used for more than just 2 hours at a time.

Water Vapor

Another byproduct of combustion ventless units send into your home is water vapor. The high levels they release (about a 1/2 gallon per hour!) heavily collect on walls, furniture, and appliances.

Appearance

A common complaint among new ventless owners is that the flame looked better on the website than it does in their living room. Anyone can Photoshop a flame onto a log set, but a ventless unit can never look that way in real life. When a unit is vented, the fire is lush and dances between the logs like a wood fire. With ventless units, the burner must be completely seperated from the log set to allow the flow of oxygen. Not only this, but the lack of a flue (and thus an established draft) results in flames that barely reach past the logs.

Legality

The EPA simply does not support ventless units, no matter how well maintained. They are already outlawed in California, and will likely become illegal throughout the rest of the country by next year.
