Description

The ZOSIA ECO Insert has a large combustion chamber made of cast iron. It is ideal for homes that have recuperation systems due to its tightness. Its technical features also contribute to the fact that the insert meets ecodesign requirements.

This multi fuel log burner has been designed to provide efficient heating while maintaining ecological combustion. It is also durable and long lasting.

CONVENIENT USE

An air curtain is also included in the device. The airflow is evenly distributed, sweeps glass, and reduces soot deposition. You can maintain a clean and attractive window for many years.

The ash can be collected in a container, and the grate is fitted to the insert. This makes it easier to keep the insert clean. The insert also has a removable fence that prevents wood from falling into the hearth, making cleaning the fireplace much easier.

The  multi fuel log burner insert fireplace is equipped with two back plates, allowing for straightforward disassembly.

The handle is perforated to prevent excessive heating. This feature has a positive impact on the comfort level of using the fireplace.

This insert is designed for modern heating systems and can also be used as an insert for wood-burning fireplace installations.

 

MAXIMUM ENERGY USE

The multi fuel log burner insert has externally mounted radiators that are densely spaced. This solution increases the area of heat transfer to the surrounding environment and also increases the mass of the fireplace.

The deflector extends the exhaust pathway, allowing for the burning of fuel particles. This process increases combustion efficiency and ensures better energy use while minimizing harmful substance emissions into the air.

The insert has a triple chamber combustion venting system. This makes the process of burning wood in the insert both environmentally friendly and economically efficient.

An air inlet of 125 mm size is used to supply primary air from outside. The air intake is at the bottom of the insert.

The holes in the rear wall provide a secondary air supply, which facilitates a system of afterburning. This system is responsible for both the combustion of gases and reducing harmful substance emissions into the environment. The system improves the efficiency and reduces CO emissions.

The device has a system for cleaning the glass. Thanks to the air curtain, airflow is distributed evenly and the glass is swept. Soot is kept to a minimum. The glass will remain clean and effective for a longer period of time.

All three systems have independent venting controls for the combustion chamber, allowing the user to better control the combustion process.

The insert multi-fuel stove and efficient wood burner provide improved heat efficiency for everyday use.

ECOLOGICAL COMBUSTION

The unit meets both the Ecodesign standard and the BImSchV2 standard, which limits the CO emissions.

The eco wood-burning stove has been designed to provide cleaner combustion, reliable heating efficiency, and environmental consciousness.

 

SAFETY AT THE HIGHEST LEVEL

The cast iron insert front is fitted with a decorative heat-resistant glass that can withstand temperatures up to 660°C. The glass installed has a certificate for quality and safety.

Cast iron walls and radiators with a thickness of 8 mm are made from high-quality cast iron and have a densely packed design to ensure maximum heat and safety.

This robust cast-iron fireplace insert can also be used as a cast-iron log burner or dependable log insert to heat long-term.

 

ECOLOGICAL COMBUSTION

Due to the construction of the  multi fuel log burner  insert and the triple combustion chamber ventilation system, the insert meets the Ecodesign requirements. Moreover, the tight combustion chamber makes the insert a perfect solution for homes with recuperators.

The Zosia Wood Burning Fireplace Insert – 12kW is ideal for homeowners searching for a dependable 12kW multi fuel stove, modern insert stove wood burner, practical multi fuel stove insert, and powerful wood burning fireplace insert with efficient heating performance.
