Ancient fire pits were sometimes constructed in the floor, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or irritating smoke within the house.Fire pits grown into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The 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 throughout the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside via a ceiling or wall. These can be put against stone walls, instead of taking up the center of the space, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue 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 numerous rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were expensive to develop and maintain.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 cellar and venting a longer area on 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 out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the space. Rumford's design is the basis for modern fireplaces.
Instead it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces at this time have been a sign of wealth, which to some degree is still the idea today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they have been used for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there's frequently a corbeled brick crown, where the projecting courses of brick act as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor integrated 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 risk. The EPA writes"Smoke may smell great, but it's not great for you.Kinds of fireplacesManufactured fireplaces are made with sheet metal or glass fire 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 gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws limiting these types of fireplaces. There are also air quality management problems due to 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 liquid propane or natural gas. They are completely sealed from the place that's heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits compared to modern fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were generally based within a room, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design which was 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 newest fireplaces were composed of 2 components, the surround and the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.Real Flame Chateau 41 in.

Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider just 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 toaster, and has done so as the 15th century. The best method to gauge the output signal of a fireplace is in case you notice you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two stages. During the first phase the first heat is provided through a big glass while the flame is burning. During this time period the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next stage. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.ethanol fireplace
