They draw in cold air from the floor and blow heated air back out into your home. This adds an element of conductive and convective heating to the radiant heat typical of a basic fireplace. Grate heaters have been called many things: heatilator, hearth heater, fireplace blower, fireplace grate heater, Fireplace Furnace, tubular grate heater, etc.
Even a very efficient traditional fireplace only operates at about 15% efficiency. This is because most of the hot air generated by the fire travels up the chimney due to convection. A traditional fireplace can also draw hot air in from the room and expel it through the chimney, further lowering the efficiency. The design of the direct vent ...
Proponents claim the exhaust gas mostly consists of carbon dioxide and steam, because a rocket stove in general is more efficient at burning fuel. [14] [16] The low thermal transmittance of the heat exchange mass allows slow release of heat after the fire is out. Some people claim their rocket mass heaters are capable of sufficiently heating ...
The fireplace insert was invented in 1742 by Benjamin Franklin, which he called 'The Pennsylvania Fireplace' (also known as the Franklin Stove), in the United States.He came upon the idea as a means of using coke (a smokeless fuel made by the destructive distillation of certain types of coal) and incorporated the use of an electric blower to improve efficiency.
To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating process in two phases.
