Ancient fire pits were sometimes constructed in the floor, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where an open fire burnt with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it out through a ceiling or wall. These can be put against rock walls, instead of taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings handily. They didn't come into general use immediately, however, as they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a lengthier area at the very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant heat projected into the space. Rumford's layout is the foundation for modern kitchens.
Rather it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces at this time were a sign of prosperity, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, depending upon the plan.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which divides up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, some states and local businesses have laws limiting these types of fireplaces. They must be suitably sized to the area to be heated. There are also air quality control problems due to the quantity of moisture that they discharge in the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that is heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the purpose of fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were usually centered within a room, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, instead of their size.
From the 1800s newest fireplaces were composed of two parts, the surround and the add. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to houses.Dimplex Media Console Fireplaces GDS33L3DX1113 Joseph Media Mantel Fireplace Becker Furniture Video
Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace is not, and never was, designed to warm the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to estimate the output signal of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is provided through a large glass while the flame is burning. During this time the construction, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace media console
