Closed and open hearth for fireplaces and fireplace indoor dates open fire rather conventional, and more accurate expression of open or closed fireplace hearth. Open fireplace hearth - fireplace having open access to the firebox and fire. In the fireplace open access to the fire can be on one side (in the classical fireplaces) and fully open (suspended contemporary fireplaces). Fireplaces with open fires (open combustion chamber) give off heat, until light fire, and in most cases serve to create comfort. Open fires are associated with an open fireplace firebox made of brick, but may be open and insert a metal cassette with no doors.

Closed hearth for fireplaces - closed combustion chamber design of the fireplace. The air supply for combustion by mechanical levers, allowing to regulate the duration and intensity of burning. The design of a closed furnace with afterburner function Flue gas fireplace makes a more efficient and environmentally friendly. Door with heat-resistant glass vyderzhivat temperature to 800 * C. In some models have sealed burners mechanism lifting up the door glass (the guillotine), which allows operate the furnace in the open.

The effectiveness of open and closed furnaces fireplaces fireplace inserts efficiency of open lower as control intake air into the fireplace and the intensity of the burning complex. Heat in the open furnaces kept up until the fire is burning in the fireplace. With open fireplaces need to monitor the flow of oxygen for combustion, fire maintained. Heating of the room is as radiant heat from the inner walls fireplace firebox and convection heat from the heated liner (not all devices and structures). Modern closed hearth for fireplaces are economical and highly effective, thanks to the closed door of the firebox. Heat-outer surface of the furnace can heat a large volume of air by convection. Closed fireplace inserts cast iron or steel has a high heat output, efficiency above 70%, in fact, are not subject to deformation at high temperatures.
