Direct vent technology has become a staple in new home construction.

According to the U.S. Environmental Protection Agency (EPA), homeowners today are increasingly concerned about indoor air quality, which if compromised, can trigger respiratory ailments like asthma. The EPA states that indoor pollution sources that release gases or particles into the air are the primary cause of air quality problems in the home. It is also proven that insufficient ventilation can increase indoor pollutant levels by not circulating enough outdoor air inside the home to dilute emissions, and by not carrying indoor air pollutants out of the home.

Unlike unvented or vent free gas fireplaces, direct vent technology expels 100 percent of the fireplace’s combustion exhaust, moisture and odors outside of the home. Indoor air quality is not compromised because a sealed combustion system keeps by-products, such as carbon monoxide, nitrogen dioxide and excess moisture from entering the home.

In the late 1980s, Heat & Glo invented the direct vent gas fireplace, revolutionizing the hearth industry. Recognized by the Energy & Environmental Building Association as one of the top 25 technology breakthroughs in residential construction, direct vent technology has become a staple in new home construction.

With a broad range of sizes and easy placement advantage, direct vent gas fireplaces, stoves and inserts produce highly-efficient heat and can be installed almost anywhere in the home. They are the most requested type of hearth system by U.S. consumers today.

“In addition to being the focal point of a room, homeowners want their fireplaces to create warmth while maintaining indoor air quality,” said Dave Miller, Heat & Glo brand manager. “This is made possible with direct vent systems, which drive 100 percent of the fire’s combustion exhaust outside the home, protecting indoor air.”

Heat & Glo’s direct vent gas technology also helps builders earn green building points. It is the preferred technology in every green building program, including the National Association of Home Builders (NAHB) Green Home Building Standards, U.S. Green Building Council (USGBC) LEED® for Homes and ENERGY STAR’s® Indoor Air Package. It is also an American Lung Association Midwest Health House® program Clean Air Choice™.
