Additionally, fireplaces CORNEA A have accumulation heat exchanger, keeping heat energy for its subsequent radiation, thus increasing overall heat efficiency of the unit. The combustion chamber is cladded with fireclay fittings. Standard model is without grate, but it can be easily modified to a model with the grate. Standard flue gas outlet is on the top or in the back. Secondary air supply onto the inner side of the door is an efficient solution to avoid dirt deposits, hence, you will not be distracted from viewing into the flames. Primary and secondary air intake control is made using one control element. Sufficient air for an optimum combustion process will be provided by the EAI system (external air intake from the exterior). Besides, the stove can be fitted with one or several nice firewood storage boxes.
