Prity K3 GT D Wood-Burning Stove – 8.1 kW

The Same Precision Firebox. A Bolder Presence in the Room.

The Prity K3 GT D shares its firebox, output, and certified efficiency with the K2 GT — but it's built for a different kind of room. Where the K2 GT is tall and narrow, the K3 GT D is wider, squarer, and more imposing: a stove that commands attention rather than blending into the background, available in black, burgundy, or ivory to match any interior.

With 8.1 kW of heat output and 80.4% efficiency, it is suitable for spaces of up to approximately 62 m², depending on insulation, ceiling height, and room layout. The EU Energy Efficiency Class A+ rating puts it among the most efficient solid fuel appliances available in its category.

How Much Space Can It Heat?

The K3 GT D delivers 8.1 kW, suitable for heating spaces of up to approximately 62 m² in well-insulated modern homes — ideal as the primary heat source for a large living room, open-plan kitchen-living area, or a substantial rural property room. It also works exceptionally well as supplementary heating in larger homes.

Convection Above and Below

Unlike simpler stoves that rely on radiant heat alone, the K3 GT D works on two levels. Louvered convection vents at the top and bottom of the body draw cool air in at floor level, warm it against the firebox casing, and release it from the upper vents — creating a steady convection loop that distributes warmth across the room more evenly than radiation alone.

The result is a stove that feels warm throughout the space quickly, not just in the immediate line of sight of the glass door.

The firebox itself is lined with heat-retaining vermiculite panels for sustained heat output after the active burn, and fuel consumption at rated output is just 2.5 kg/h — economical for a stove of this heating capacity.

Austria-Eligible. EU Ecodesign Class A+.

At 80.4% КПД efficiency, the K3 GT D meets Austria's strict §15a efficiency requirement and qualifies for sale across all primary EU markets. Its A+ energy class and 71% seasonal efficiency (ηs) confirm it exceeds the EU Ecodesign minimum comfortably.
