Vent-Free Blue Flame Heater with Modulating Hydraulic Thermostat

Bring reliable warmth and exceptional comfort to your home with the Vent-Free Blue Flame Gas Heater, a premium supplemental heating solution designed to combine efficient performance with convenient temperature control.

Available in 10,000, 20,000, and 30,000 BTU models, the Blue Flame Series delivers consistent warmth while offering flexible installation options for a variety of residential spaces.

Unlike radiant heaters that primarily warm nearby objects, blue flame technology heats the surrounding air, allowing warmth to rise and circulate naturally throughout the room. The attractive white cabinet and visible blue flame create an inviting appearance that complements both traditional and contemporary interiors.

Equipped with a hydraulic thermostat, the Empire BF Series automatically regulates burner operation to help maintain your preferred comfort level. The 20,000 and 30,000 BTU models feature modulating controls that adjust flame intensity as heating demands change.

Designed for dependable operation, these heaters deliver 99.9% heating efficiency and require no electricity for basic heating operation, making them a valuable supplemental heat source during power outages.

Choose from dedicated Natural Gas or Liquid Propane models, with optional blowers and floor stands available to customize your installation.

Whether you’re adding warmth to a living room, supplementing an existing heating system, or enhancing comfort during cooler months, the Blue Flame Heater combines practical functionality with trusted American craftsmanship.
