Historical fire pits were sometimes constructed in the floor, in caves, or at 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 house.Fire pits developed into raised hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had 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 allow the roof vents to be covered so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it out through a wall or roof. These can be placed against stone walls, rather than taking up the center of the space, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, as 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 that greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer place at the very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and from the construction. The shallow design also improved greatly the quantity of radiant heat projected to the space. Rumford's design is the basis for modern fireplaces.
Rather it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time have been a sign of wealth, which to some degree remains the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. 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. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

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 exterior walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws restricting these types of fireplaces. There are also air quality management 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 liquid propane or natural gas. They are totally sealed in the place that is heated, and port all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were generally based within a room, allowing more people to collect around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, as opposed to their size.
From the 1800s most new fireplaces were made up of two parts, the surround as well as the add. The encircle consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance to homes.Best 25+ Stacked stone fireplaces ideas on Pinterest Stone fireplace makeover, Stone fireplace Video
Some fireplace components incorporate a blower which transports 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 enhanced by means of a fireback, a piece 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 manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. The best method to gauge the output of a fireplace is if you detect you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first stage the initial heat is provided through a large glass while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the next stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.tile fireplace
