Historical fire pits were sometimes built from the ground, within caves, or at the middle of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced toxic and/or annoying smoke inside the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open flame burnt with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it out through a wall or roof. These can be placed against stone walls, instead of taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, however, since they were expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting out a longer place on top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing the smoke up and out of the building. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's layout 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. Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time have been a symbol of prosperity, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, depending on the plan.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house 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, where 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 in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric 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 kinds of fireplaces. There are also air quality control problems because of the quantity of moisture that they discharge in the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the place that's heated, and port all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were fire pits than contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally 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, necessitating a standardization of fireplaces. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s most new fireplaces were composed of two components, the surround and the insert. The surround consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.Best Fake Fireplace Logs Nice Fireplaces Firepits Video
Some fireplace components include a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also increased with the use of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal method to estimate the output of a fireplace is in case you notice you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two stages. During the first phase the first heat is offered through a large glass window while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fake fireplace logs
