Frequently Asked Questions

What is the warranty for the Firebull S12 stove?

Firebull S12 stoves offer a three-year warranty that covers all manufacturing defects and ensures trouble-free operation.

Does the three-year warranty also cover the door glass?

The warranty does not cover the door glass, as it is considered a consumable material that can be mechanically damaged during normal use.

What is the lifespan of the Firebull S12 stove?

Firebull S12 stoves have an expected lifespan of up to 20 years. To achieve this longevity, it is important not to overload the stove and to operate it in accordance with the maximum specified output to avoid overheating or heating the unit until it glows red.

Does the Firebull S12 stove comply with current standards, and if so, which ones?

Yes, the Firebull S12 stove complies with current standards, including EN 13240:2001, ECODESIGN 2022, and the German BImSchV Stage 2 standard. These certifications confirm that the stoves are not only highly efficient but also environmentally friendly due to low emissions and optimal fuel utilization.

Can I use the Firebull S12 stove as a primary heating source?

Yes, Firebull S12 stoves are ideal for use as a primary heat source. Before purchasing, we recommend evaluating the output and heating capacity to ensure they match the space to be heated.

What is the heating capacity of the Firebull S12 stove?

The Firebull S12 hot-air stove has a heating capacity of 180 - 500 m³, making it suitable even for large rooms.

What fuel is suitable for the Firebull S12 stove?

The Firebull S12 convection stove allows for the combustion of wood logs or briquettes up to 72 cm in length, with the ideal fuel length being 60 cm.

How long does the Firebull S12 stove burn on a single full load?

When using dry, unsplit wood logs of the optimal 60 cm length (maximum 72 cm) and setting the air dampers to low-power combustion, the Firebull S12 stove can maintain a fire for up to 4 hours without the need for further stoking.

How long will the Firebull S12 stove burn from the last full load until it completely cools down?

The Firebull S12 hot-air stove can burn for up to 10 hours after the last load of dry, unsplit roundwood with a maximum length of 72 cm. This performance is achievable with the air dampers correctly set to minimum combustion and after operating for at least 8 hours, allowing sufficient hot embers to accumulate in the firebox. Once completely cooled, however, the fire must be restarted, for example, using matches.

How often must ash be removed from the Firebull S12 stove?

Ash needs to be removed from the Firebull S12 stove approximately once or twice a month. The stoves are designed without a grate or ash pan; therefore, the fire burns directly on the bottom of the stove. After cooling, a new fire is started on a layer of ash. Ash is removed only when it reaches the level of the lower part of the loading door, where it might begin to fall out. A shovel, metal bucket, or ash vacuum cleaner is used. Repeated re-combustion results in minimal waste, and the ash also protects the bottom of the stove from high temperatures
