Historical fire pits were sometimes constructed from the ground, within caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor flame pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits developed into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open fire burned with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside through a wall or roof. These could be placed against rock walls, rather than taking up the center of the space, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general use immediately, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting a lengthier place on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant heat projected to the space. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and also deflected unnecessary ornamentation. Instead it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time have been a sign of wealth, which to some degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, based upon the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.
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 types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws restricting these types of fireplaces. They must be suitably sized to the area to be heated. Additionally, there are air quality control issues due to the amount of moisture that they discharge in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the place that is heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the house. These fire pits were usually based within a space, allowing more people to collect around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, as opposed to their size.
By the 1800s newest fireplaces were made up of two parts, the surround and the add. The encircle comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance into homes.Necessories Colonial Outdoor Fireplace Fireplaces Chimineas at Hayneedle Video
Some fireplace units incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced with the use of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, and never was, designed to heat the air. The best method to gauge the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two stages. During the first stage the first heat is provided through a big glass window while the flame is burning. During this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.outside fireplace
