Ancient fire pits were sometimes constructed from the ground, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The drawback of early indoor fire pits was that they generated toxic and/or irritating smoke inside the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burned with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it outside through a ceiling or wall. These can be placed against stone walls, instead of taking up the center of the room, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use immediately, however, since 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 efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing up the smoke 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 fireplaces.
Rather it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces now have been a symbol of prosperity, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficiency, based on the design.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, where the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves 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 metallic liners than with the standard masonry chimney, which divides up all but the rain. A few 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 various studies, fireplaces could pose a significant health threat. The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces could 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. In the United States, several states and local counties have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems due to the amount of moisture that they release in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the area that is heated, and vent all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits than contemporary fireplaces.

It had been smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were composed of two components, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite.

Some fireplace components include a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. The best way to gauge the output of a fireplace is if you detect you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is offered through a big glass while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces with no glass fire window just provide heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace candle holder
