One organization has championed the growth of America's Vent-Free gas products industry. This organization is the Vent-Free Gas Products Alliance
The Vent-Free Gas Products Alliance is a coalition of members of the Air-Conditioning, Heating and Refrigeration Institute's (AHRI's) Vent-Free Gas Products Section.
The Alliance exists to assure that current markets are preserved and that barriers are removed in all trade areas for future growth of the industry. The outcome is increased use and sales of vent-free gas heating products and that consumers are informed about the benefits of using these products.
The Alliance is responsible for the continued success of Vent-Free gas products in the U.S. with more than 20 million units installed in the U.S. Because of their proven track record, Vent-Free gas products are now accepted in most states.
