Ancient fire pits were sometimes constructed from the floor, within caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated toxic and/or annoying smoke within the house.Fire pits developed into elevated hearths in structures, but venting smoke depended on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where a open flame burnt with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside through a ceiling or wall. These could be put against rock walls, rather than taking up the center of the space, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage immediately, however, as they were expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. 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. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and deflected unnecessary ornamentation. Rather it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces now were a symbol of wealth, which to some degree remains the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficacy, depending upon the design.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

Decorating Your Mantelpiece for Spring
On the exterior there's frequently a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health risk. The EPA writes"Smoke may smell good, but it's not good 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.A couple of kinds 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, several states and local businesses have laws limiting these types of fireplaces. Additionally, there are air quality management problems because of the quantity of moisture they release into the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the place that's heated, and port all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were usually based within a room, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of the time were the Adam Brothers. They perfected a style 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 dimensions.
From the 1800s most new fireplaces were composed of two components, the surround as well as the add. The surround consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The insert was fire burnt, and was built of cast iron often backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.25+ best ideas about Over fireplace decor on Pinterest Fireplace mantel decorations, Mantels Video
Some fireplace units incorporate a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased 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 are also manufactured from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. The best method to estimate the output signal of a fireplace is if you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two stages. During the first stage the initial heat is offered through a big glass while the fire is burning. During this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace decor
