Kalfire Gi Series Gas Fires

Frequently Asked Questions

What makes Kalfire Gi Series gas fires different from other smart fireplaces?

The Gi Series combines revolutionary Gi Technology that reduces gas consumption by up to 80% with patented KalSense intuitive control and genuine flame-enhancing features like Ember Glow and optional Natural Spark Generator. Unlike many smart fireplaces that prioritise tech over fire quality, Gi models maintain beautiful, dynamic flames while integrating seamlessly with home automation and smartphone control.

What is Gi Technology and how does it save gas?

Gi Technology uses three independent gas valves controlled by stepper motors to alternately increase and reduce gas supply in a sine wave pattern. This creates naturally fluctuating flames that look more realistic while dramatically reducing consumption. The Comfort button saves up to 80% gas, and Comfort+ dynamically manages flames to reach a set room temperature efficiently.

How does KalSense work?

KalSense is Kalfire's patented control sensor with a coloured ring indicator that shows fireplace status intuitively. It enables precise flame adjustment, thermostat control with automatic shut-off, and seamless integration with the Mood system for personalised fire settings. The coloured ring changes to indicate different modes and temperatures.

What smart home features does the Gi Series offer?

All Gi models include remote control, Wi-Fi connectivity, the free Kalfire Connected app for iOS and Android, and integration with popular home automation systems. The Mood function stores up to 10 custom fire programmes with names and colours, while SDA remote diagnostics enable faster, more efficient servicing.

What efficiency ratings do Kalfire Gi Series gas fires achieve?

Kalfire Gi Series models achieve 81% efficiency with B-rated energy performance on most models. The Gi 75/59F achieves C-rating with 75-79% efficiency depending on gas type. The Comfort and Comfort+ functions can reduce running costs significantly while maintaining attractive flame pictures.

Which Kalfire Gi Series model is best for my room size?

For smaller rooms up to 70m3, the compact Gi 75/59F (6.6kW) is ideal. Medium rooms between 70-120m3 suit the Gi 105/59F or Gi 105/79F (7kW output). For larger spaces or open-plan areas where panoramic views are desired, the Gi 115/55S three-sided model (6.7kW) creates a stunning focal point visible from multiple angles.

What is the Natural Spark Generator (NSG)?

NSG is Kalfire's patented optional feature that creates small sparks escaping from the flames and burning out slowly. This amazingly realistic simulation of a wood fire is unique to Kalfire and adds authentic crackling atmosphere to your gas fireplace.

What installation requirements do Kalfire Gi Series fireplaces have?

Gi Series fireplaces require a balanced flue system with 100mm air inlet and exhaust, professional installation by a Gas Safe-registered engineer, and minimum 180mm wall thickness with 50mm clearance to combustibles. The E-Box design conceals the technical unit under the hearth floor for a seamless finish.

Are Kalfire Gi Series fireplaces environmentally friendly?

Yes. All Gi models are H2-Ready for hydrogen gas compatibility and work with natural gas and propane. The Gi Technology's up to 80% gas reduction in Comfort mode significantly lowers running costs and emissions. The sealed combustion system and high efficiency ensure minimal environmental impact.

Do Kalfire Gi Series gas fires come with a warranty?

Yes, every Kalfire Gi Series gas fire includes a 5-year warranty on the firebox and manufacturing defects. Electrical components, KalSense sensors, remote controls and app connectivity are covered for 2 years. Annual servicing by a qualified Gas Safe engineer maintains warranty validity.
