Historical fire pits were sometimes constructed from the floor, in caves, or at the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or annoying smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open flame 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.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside through a ceiling or wall. These can be put against stone walls, instead of taking up the middle of the room, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from 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 multiple rooms in buildings handily. They didn't come into general use immediately, however, as they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting out a longer area at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Rather it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces now were a symbol of wealth, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric 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 businesses have laws limiting these kinds of fireplaces. There are also air quality management issues because of the quantity of moisture they discharge in the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been 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 outside of the structure.

It had been smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s most new fireplaces were made up of 2 components, the surround as well as the insert. The encircle consisted of the mantlepiece and sides affirms, typically in wood, granite or marble.

Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace isn't, and never was, intended to warm the atmosphere. The ideal way to estimate the output of a fireplace is in case you notice you're turning the thermostat up or down.
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 for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the initial heat is offered through a large glass window while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace stone
