Do ventless heating products harm indoor air quality?
Ventless heaters, fireplaces, stoves and log sets are proven to meet today’s most rigorous air quality standards. The American Gas Association Research (AGAR) laboratories investigated the impact of emissions from ventless gas products on the home environment. The researchers took into consideration the climate in the country’s five Department of Energy heating regions, various types of housing constructions and different volumes of space to be heated. After running hundreds of thousands of computer-based scenarios, results were confirmed by tests run at the American Gas Association test house facility. AGAR researchers concluded that “ventless gas heating products performed well within nationally recognized guidelines for indoor air quality.” This research shows that ventless gas heating products meet applicable emissions requirements, even when used over extended time periods, among sensitive populations and with units whose maximum heat output exceeds the requirements of the space.
