Kalfire G130/37S Gas Fire - Three Sided

The Kalfire G Series features proprietary 3D-burner technology that creates genuinely dynamic flame patterns, not static rows of flame. Combined with efficiency ratings up to 87%, H2-Ready hydrogen compatibility, and an exceptionally wide size range from 60cm to 170cm, the G Series offers both performance and design flexibility that few competitors match.

The 3D-burner is Kalfire's horizontally built gas burner that creates multi-layered, naturally moving flames across the full width of the fireplace. Unlike conventional linear burners with uniform flame rows, the 3D-burner produces varying flame heights and movements that closely mimic the unpredictable nature of a real wood fire.

The G Series offers five distinctive filling options: standard ceramic log set, exclusive ceramic log set with longer pieces for enhanced realism, contemporary white stones, modern grey stones, and premium Cryptonite crystalline stones with unique reflective properties.

The G Series is available in four configurations: Front-facing (single-sided), Corner Left, Corner Right, and Three-Sided panoramic. This allows the fireplace to suit everything from standard chimney breasts to corner features and central room dividers.

Kalfire G Series models achieve efficiency ratings from 73% to 87% depending on model and gas type. The G100/41F leads the range at 87% efficiency on G20 natural gas. Most models achieve C-rated energy efficiency, with some D-rated options on specific gas types.

For smaller rooms up to 60m3, the G60/48F or G100/41F are ideal choices. Medium-sized rooms between 80-140m3 suit the G120/41F, G130/37S or G160/41F. Large open-plan spaces over 140m3 benefit from the commanding G170/37S three-sided model with its panoramic flame views and 10.8kW output.

Kalfire G Series fireplaces require a balanced flue system with 130/200mm connection, professional installation by a Gas Safe-registered engineer, and adequate clearances to combustible materials. They feature closed combustion with external air supply. All models are CE certified and comply with UK Building Regulations.

Yes. All G Series models are H2-Ready for future hydrogen gas compatibility and work with multiple gas types including natural gas and propane. With efficiencies up to 87%, they extract maximum heat from every unit of gas, reducing fuel consumption and emissions compared to older, less efficient fireplaces.

Yes, every Kalfire G Series gas fire includes a comprehensive 5-year warranty on the firebox and manufacturing defects. Electrical components and control systems are covered for 2 years. Annual servicing by a qualified Gas Safe engineer is required to maintain warranty coverage.

The G Series offers three interior finishes: Flat for a clean, minimalist look; Design featuring sculpted architectural details for added depth; and Black ceramic glass for a dramatic, contemporary reflective effect that makes flames appear to float in space.
