Solution

Usually, the hottest part of the fire is the ember bed and not the flame. Many fireplaces produce less warmth because conventional flat grates have a design in which the heat emitting embers are blocked by the firewood. If the embers are not visible, radiant heat is not being emitted into the home. Furthermore, the embers that are exposed are usually lying on top of the grate, aimed up at the chimney, and this is exactly where the heat is going to travel. In addition, elevated grate fires commonly draw in freezing make-up air from outside to feed the wild chimney draft; actually dropping the room temperature.

A conventional flat grate burns wood fast and inefficiently because the entire pile of wood quickly becomes engulfed in flames all at once like a primitive camp fire. The rate of burn is also accelerated because the draft enters from the underside of the grate. This fans the fire wildly and radiates wasted heat up the chimney. Special elevated grate burns wood slowly by maintaining a tall, yet shallow, stack of firewood; optimizing fireplace efficiency. Gravity slowly feeds wood into the lower chamber of the grate where it is burned. The reserve wood at the top of the stack is not directly in the line of heat with the burning fire below, keeping it from combusting prematurely. The end result is a steady, efficient, heat emitting fire.

The Wall of Fire grate maintains a vertical wall of heat emitting embers, positioned to face the living space. This means the hottest part of the fire is aimed directly into the home. Only the smoke and flame are aimed up the chimney; the exact opposite of a flat grate. The intensity of the heat is maximized by the draft which enters the lower front of the grate and in turn, fans the embers like a bellows. On average, heat output is more than doubled compared to a similar sized flat grate. This is all achieved without the use of fans or blowers, just simple physics. Because of this, Wall of Fires grates are an ideal alternative to expensivefireplace inserts. Wall of Fire grates direct considerably more heat into the home compared to what is lost up the chimney resulting in a positive room temperature increase.
