Fast, cosy warmth – thanks to 3.4KW heat output

A 3.4KW rating denotes the heater's thermal output capacity and the rate at which the burner releases heat into a room. Consistent combustion creates steady convective and radiant warmth.

Rooms reach comfortable temperatures quickly, matching user comments about effective heating even on low settings.

Enhanced safety for indoor use – with Oxygen Depletion Sensor (OxySafe) and FSD

OxySafe monitors oxygen levels and triggers a safety response if levels fall, while the Flame Supervision Device detects loss of flame and interrupts gas flow. Both systems act automatically when unsafe conditions are detected.

Safer operation for occupied rooms, reducing the risk from low-oxygen conditions or accidental flame failure.

Straightforward control and authentic ambience – with easy ignition and real flame fire

User feedback highlights simple ignition mechanisms and intuitive controls that allow direct adjustment of the burner. A real flame presents visible combustion rather than simulated effects.

Quick to light and adjust, the heater adds a reassuring, stylish focal point to a room while remaining simple to operate, supported by a 24-month warranty.
