💨 Staying Warm Vent Free

Love the idea of having a fire in the fireplace, but thought it was impossible since you don’t have a chimney? Guess what, now you can. Add a vent-free gas heating unit to your home. More than 30 million families worldwide and over 4 million US households already rely on vent-free gas heating products.

Energy efficient

A vent-free gas-heating appliance operates without a chimney or vent, so no heat can escape — saving you money. It literally costs only pennies per hour to operate. You can install one just about anywhere, even an inside wall. A variety of vent-free gas products are available, including space heaters, fireplaces, fireplace inserts and gas logs. Use them in hard-to-heat areas such as a basement, garage, room addition, sun porch, or greenhouse. These appliances are energy efficient to 99%, and can provide warmth during power outages.

How do they work?

Vent-free gas heating products operate on natural or propane gas through a permanent line connected to a burner within the heating appliance and require no electricity. Appliances are equipped with a unique safety pilot system called an oxygen depletion sensor, or ODS. The ODS is the proven technological innovation that revolutionized the safety of vent-free gas heating appliances. The ODS automatically shuts off the gas supply in the rare event that the oxygen level in the room falls to unsafe levels. Vent-free gas heating products meet or exceed the most current and applicable nationally recognized standards and recommendations for indoor air quality.
