In the 1980s, Empire became the first to market a gas-fired heater that achieves 80-percent efficiency, and in 2006, Empire marketed the first vented gas fireplace to achieve 90-percent efficiency. From early floor furnaces (a forerunner to central heating systems) to console heaters to wall furnaces, to gas fireplaces and log sets, to the super-efficient Mantis fireplace system, Empire has adapted to market requirements.
