    Overview

    This 25 MJ/h Portable Gas Convection Heater is designed to deliver powerful, efficient warmth for larger living spaces and open-plan areas. With a high gas input of 25 MJ/h and a 6.1 kW output, it can heat rooms up to 97 m2, making it a practical choice for homes needing fast, even comfort during cooler months.

    Using convection heating, the built-in fan helps circulate warm air throughout the room, reducing cold spots and creating a more consistent indoor temperature. The heater is available in both Natural Gas and LPG models, giving households flexibility based on their gas connection requirements.

    Everyday operation is made simple with a touch glass digital control panel and included remote control with display. Users can choose from Auto, ECO and Boost modes to suit changing comfort needs, while the 24-hour delay on/off timer allows heating to be scheduled in advance.

    Safety is built into the design, with flame failure shut off to automatically stop the gas supply if the flame goes out, along with a safety tip over switch that shuts the heater down if it is accidentally knocked over. A child lock adds extra peace of mind in family homes.

    Available in Graphite, Silver and White, this portable unflued gas heater combines strong performance, convenient controls and modern styling for reliable home heating.
