Empire builds a full line of heaters for nearly every application – from vent-free models (in blue flame and infrared) to wall furnaces and console heaters in direct-vent and B-vent. At more than 90-percent efficient our UltraSaver models provide more heat for your energy dollar than any other vented system you can buy. All of our Empire-branded heaters are made in the USA.

Vent-Free systems draw room air to support combustion in a clean burning blue-flame or radiant-plaque system.  Rated at 99.9 percent efficient, vent-free heaters release nearly all of the available heat energy into the room.

To ensure safe operation, all vent-free systems include an Oxygen Depletion Sensor (ODS) to automatically turn off the heater if room oxygen level drops to an unsafe level.

Our Blue Flame heaters warm the air, which rises to create natural circulation in the room. Ideal for any supplemental heat application.Choose one of our imported HearthRite blue flame heaters to warm your room for a great value.

The BF10W and BF20W produce an inviting atmospheric warmth quickly and efficiently.

The BF10W is equipped with a hydraulic thermostat with a constant 10,000 Btu input, while the BF20W is equipped with a modulating hydraulic thermostat that modulates from 8,500 Btu to 20,000 Btu for continuous temperature control.

              Replaced same brand propane heater

              We had our first propane heater for 25 years. We felt it wise to upgrade for efficiency. We are very happy with the new one from US Fireplace. Thank you.
