The PROMETEY EKO MINI is a Bulgarian-made Eco Design wood stove rated at 6.4 kW nominal and 9 kW maximum heat output. Its firebox is lined with refractory bricks and the glass door keeps the flames in full view. The stove is free-standing, with a steel top plate and a Ø 130 mm flue connection.

80.5% efficiency, energy class A+

Conventional stoves without Eco Design work at roughly 60% efficiency, sending almost 40% of the heat up the chimney. Here only about 20% is lost, and the rest stays in the room.

Airtight build cuts wood use by about 30%

The body is sealed on all sides and air enters only through the intended openings, so combustion follows the regulator settings precisely. A season that would take 6 tonnes of logs in an ordinary stove needs around 4 tonnes here.

Air controls for 3–4 hours of overnight burn

The primary air control at the bottom of the door is opened for lighting, then closed. The secondary control above it gives fast warm-up fully open, nominal output at about 50% and a long, slow burn at about 10%.

30 x 38 x 29 cm firebox with refractory lining

The ceramic bricks store heat and keep releasing it after the logs burn down. Ash collects in a removable ash pan, which should only be emptied once cold.
