Ancient fire pits were sometimes constructed in the ground, in caves, or in the center of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open fire burnt with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it outside 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 rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage instantly, however, as they were expensive to develop and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer place at the very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing up the smoke and from the building. The shallow design also improved greatly the quantity of radiant heat projected to the room. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and also deflected unnecessary ornamentation. Instead it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality stone. Stone fireplaces now have been a symbol of prosperity, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, based on the design.Historically they have been used for heating a home, 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.

On the exterior there's often a corbeled brick crown, where the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these kinds of fireplaces. There are also air quality control issues because of the amount of moisture they release into the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the place that's heated, and port all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also functioned as a gathering place within the home. These fire pits were generally centered within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of two parts, the surround as well as the add. The encircle consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Linear Fireplace on Pinterest Contemporary Fireplaces, Gas Fireplaces and Modern Fireplaces Video
Some fireplace units include a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a piece of metal that sits behind the flame 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 effect of heating of the air. 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 way to gauge the output of a fireplace is if you detect you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the first heat is provided through a big glass while the flame is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.linear fireplace
