ZOSIA ECO insert is a fireplace with a large cast iron combustion chamber. Due to its tightness, it perfectly suits homes with recuperation. Moreover, its technical characteristics make a contribution that the insert meets the Ecodesign requirements.



The device is additionally equipped with a clean glass system - thanks to the so-called air curtain. The air stream is distributed evenly, sweeps the glass and minimizes the deposition of soot on it. This allows you to maintain a attractive and clean window for a long time.

Keeping the insert clean is easier with a fitted grate and a container where the ash is collected. In addition, the insert has a removable fence, which prevents the wood from falling out of the hearth and makes cleaning of the fireplace easier.

The fireplace insert is equipped in double back plate, with easy disassembly of the inner back. 

The special perforated design of the handle protects against excessive heating, which has the influence on the high comfort of using the fireplace.



The insert is equipped with an externally mounted densely spread radiators. Due to such a solution, the heat transfer area to the environment is much higher and at the same time the mass of the fireplace is increased.

Burning of fuel particles is accomplished due to the equipped deflector which extends the exhaust path. This process also increases the efficiency of combustion and guarantees a better use of energy and at the same time minimizes the emission of harmful substances into the atmosphere.

The device has a triple combustion chamber venting system, therefore the wood burning process in the insert is ecological and most importantly economical.

The supply of primary air to the insert is performed from the outside due to the built-in air inlet (in size of 125 mm). The air intake is located in the bottom part of the insert.

Secondary air is supplied by the holes in the rear wall of the furnace, which creates an afterburning system. The system is responsible for the burning of the gases and the reduction of harmful substances emissions to the environment. It improves the efficiency of the fireplace, what have a direct influence on very low CO emission.

The device is equipped with a clean glass system - thanks to the so-called air curtain airflow is spread evenly, the glass is sweeped and soot settling is reduced to minimum.This allows you to maintain an effective and clean look of the glass for a long time.

The combustion chamber venting control regulation is independent for all three systems so that the user has better control over the combustion process.  



The unit meets the requirements of Ecodesign standards and the restrictions of the BImSchV 2 standard, which determines the maximum CO emission.



Cast iron front of the insert is equipped with decorative heat resistant glass which can withstand a temperature of up to 660°C. The installed glass has a certificate of quality and safety.

Densely spaced radiators and furnace walls made of high quality 8 mm thick cast iron guarantee safety of operation and maximum use of heat.



Due to the construction of the insert and the triple combustion chamber ventilation system, the insert meets the Ecodesign requirements. Moreover, the tight combustion chamber make that the isnert is perfect solution for homes with recuperators.
