Historical fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/or irritating smoke within the house.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open flame burned with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside through a ceiling or wall. These can be put against stone walls, rather than taking up the center of the room, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use instantly, however, since they were expensive to develop and maintain.Benjamin Franklin developed a convection room 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 a lengthier area on top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design also improved greatly the amount of radiant heat projected to the room. Rumford's design is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces now have been a sign of wealth, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, based on the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick act as a drip route 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 difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a significant health threat. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
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 types of fireplaces. There are also air quality control issues due to the quantity of moisture they discharge into the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the area that's heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits than modern fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the home. These fire pits were usually based within a room, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. Along 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 that has been used for generations. It was smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of 2 components, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was fire burnt, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into houses.Fireplace Remodel Traditional Living Room Indianapolis by Natural Valley Recycled Granite Video
Some fireplace units incorporate a blower which 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 can also be enhanced by means of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced 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 effect of heating of the atmosphere. An open fireplace isn't, 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 best method to gauge the output of a fireplace is if you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two phases. During the first phase the first heat is provided through a big glass window while the flame is burning. In this time 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 2 daily firings are enough to guarantee a constant room temperature.fireplace remodel
