Ancient fire pits were sometimes built from the ground, in caves, or at the middle of a hut or dwelling. 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 irritating smoke inside the house.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where a open flame burnt with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside via a wall or roof. These could be placed against stone walls, rather than taking up the middle of the space, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely 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 did not come into general use immediately, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a lengthier area at the very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design improved greatly the amount of radiant warmth projected to the room. Rumford's layout is the basis for modern kitchens.
Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces now were a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficacy, depending upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a neck, 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 outside walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor integrated into the cap or crown.
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 substantial health threat. The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the United States, some states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management problems because of the amount of moisture that they discharge into the room atmosphere, 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 from the area that's heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were generally based within a room, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround and the add. The surround consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance into houses.Home Decorators Collection Avondale Grove 59 in.

Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased with the use 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 are also made from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficiency tests consider only the impact 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 since the 15th century. The ideal method to gauge the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80 percent 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 phase the initial heat is provided through a large glass while the flame is burning. In this time the construction, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.tv stand with fireplace
