The Element4 Lucius 140 Gasfire is engineered for large-scale interiors where both visual depth and powerful heating performance are essential. Featuring a double burner system, the flames extend across the full depth of the fireplace, creating a rich, layered fire experience with exceptional realism. This configuration allows one burner to be switched off independently, offering precise control over both heat output and flame intensity while maintaining an impressive visual effect.
Delivering a substantial heat output of up to 16.5 kW, the Lucius 140 operates on natural gas (G20/G25) and propane (G31), making it ideal for expansive living spaces and open-plan designs. Its outstanding 90% efficiency ensures that high performance is paired with energy-conscious operation. The minimum installation depth supports modern architectural integration, while optional features such as the Powerfan allow installation flexibility beyond traditional flue limitations.
