Ancient fire pits were sometimes constructed in the floor, in caves, or in the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or annoying smoke within the house.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where an open fire burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside via a ceiling or wall. These could be put against stone walls, rather than taking up the center of the room, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a longer place on top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and from the construction. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Instead it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces now were a symbol of prosperity, which to a degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficiency, depending on the plan.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, some states and local counties have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control problems because of the quantity of moisture that they release in the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the area that is heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally centered within a room, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were composed of 2 parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burned, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.Fireplaces Outdoor Kitchens LanChester Grill Hearth Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace isn't, and never was, intended to warm the air. The best method to gauge the output signal of a fireplace is if you detect you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two stages. During the first phase the initial heat is offered through a big glass window while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.fireplaces
