Homes experience lowered levels of oxygen all the time – from fans, candles, unnoticed drafts, etc. – which causes incomplete combustion in a gas-fired unit. Incomplete combustion produces carbon monoxide…and without a vent, it has nowhere to go but your living space. Some ventless users claim that they are harmless because their CO detectors have never gone off, but the truth is that CO detectors only go off if high levels are detected…meaning that low or moderate levels produced by a ventless unit fly completely under their radars. Many people who have had ventless gas units in their home for a period of time have reported anything from frequent headaches to severe health problems. However, since there is technically not enough evidence to definitively make a connection, many people decide for themselves that it must not be true. Our number one priority is safety – when it comes to playing with fire, we want to avoid taking risks when selling you a product.
Many people have heard that ventless gas units are nearly 100% efficient, and are thus the perfect solution to home heating. However, there is one fact that 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. If you do not keep them open, the risk of carbon monoxide effects skyrockets. Not only this, but they are not meant to be used for more than just 2 hours at a time!
Another byproduct of combustion that a ventless unit sends into your house is water vapor. Many people presume this would be beneficial by acting as a humidifier, but this is not the case. The high levels of water vapor released in the air (about a 1/2 gallon per hour!) heavily collects on walls, furniture, appliances, etc. causing not only mold and mildew growth but damage to your home.
A common complaint among new ventless owners is the fact that, on the manufacturer’s website, the flame looked spectacularly better than it does in their living room. Anyone can Photshop a flame onto a log set, but there is no way to make a ventless unit look that way in real life. The burner of a ventless unit must be completely seperated from the log set to allow the flow of oxygen. With a vented log set, the fire is lush and dances between the logs like a wood fire. In ventless units, the flame often isn’t even high enough to reach the logs!
The EPA simply does not support ventless units, no matter how well maintained. They are already completely outlawed in California, and will likely become illegal throughout the rest of the country by next year.
Worried about efficiency? Our vented gas units are so revolutionary they can be up to 89% efficient!
Don’t want a vent to take up space? The experts at Dean’s can work with you to determine the most efficienct placement of a unit so there is minimal venting. Some units can even be vented straight out the back!
On a budget? With our wide array of gas products, one of our salespeople can help you make the best decision for your price range.
Still want a ventless unit without a shadow of doubt? Consider an electric unit or even one of our new EcoSmart bioethanol-fueled burners (bioethanol is a fuel based on corn and sugarcane that burns completely cleanly). Both of these options are virtually 100% efficient, need zero venting, often do not require extensive installation, and are most importantly safe for you and your family. Ask one of the experts at Dean’s to fire one up and see these safe and efficient ventless solutions for yourself!
