Usage
The DORY 20 warm air and radiant stoves are ideal for heating and supplemental heating of workshops, storage rooms, industrial buildings, construction sites, as well as living spaces, guesthouses, restaurants, halls, club rooms, and recreational facilities.
These stoves can burn wood or wood briquettes.
Thoughtful Design and Rapid Heat Delivery
The DORY 20 stoves are equipped with a warm air heat exchanger and a radial fan, which, in combination with the CB secondary combustion system, ensure very high efficiency.
- Warm Air Heat Exchanger: The heat exchanger efficiently extracts heat from the flue gases, significantly reducing overall heating costs. A wiper element inside the heat exchanger allows for easy cleaning of the heat exchange surfaces. This wiper can be operated with a lever, ensuring long-term functionality and maximum efficiency of the stove.
- Rapid Heat Delivery: Another advantage of this design is the quick heat entry. Just a few minutes after ignition, warm air is distributed throughout the heated space.
- Fan Placement: The fan is strategically located at the lower rear of the stove, preventing damage during a power outage.
Clean Combustion
The combustion chamber, lined with strong fireproof bricks, maintains high temperatures in the combustion chamber and, along with the two-chamber CB secondary combustion system, ensures clean combustion that meets the strictest European emission standards.
- Low Emissions and Fuel Savings: The DORY 20 stoves produce very low emissions and have up to 40% lower fuel consumption compared to conventional stoves of similar performance.
- Durability: The fireproof bricks also protect the internal metal parts of the combustion chamber from high temperatures, significantly extending the stove’s lifespan.
Simple Performance Control
The performance of the DORY 20 stoves can be easily regulated by adjusting the primary air supply through a controllable damper in the door. The primary and secondary air supplies are optimally set at the factory to ensure efficient operation.
- Control Unit: An optional control unit can be purchased to regulate the fan speed that blows hot air from the stove. This unit can be operated in either automatic or manual mode. In the automatic mode, which is preset at the factory, the fan speeds are adjusted based on the current temperature of the stove.
