Cassette fireplace

Cassette type fireplace is an indispensable device for those who need maximum comfort and aesthetic side of the issue. It is rare to find a country house without a cassette fireplace, because this product is considered to be the most effective means for heating with wood. It is relatively easy to operate and does not cause much trouble during installation.

The basis of the cassette fireplace design is a metal sheath, inside of which there is a fire chamber (this is the cassette) made of steel or cast iron, as well as a glass door. The firebox and the shell must necessarily share the airspace. This is necessary so that the external part of the device does not transfer heat from the firebox.

The glass door provides the highest rate of efficiency - as much as ninety percent. It prevents air from escaping through the chimney. The door is equipped with small special openings, due to which exactly as much air as necessary is needed for the wood to burn.

  • The closed version of the fireplace will not upset you with such a significant drawback. Steel with refractory ceramics is used to create the unit, therefore, even having turned off the device, you will enjoy the energy emanating from it.

Cassettes differ in two more parameters: for continuous operation and periodic.

The glass door can have a different shape - rectangular, prismatic or semicircular. The choice of the door is a matter of taste, because this characteristic has no effect on the quality of work.
