Ancient fire pits were sometimes constructed from the ground, in caves, or in the middle of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open flame burned 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 wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it outside via a ceiling or wall. These could be placed against stone walls, instead of taking up the center of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general usage instantly, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a longer area on very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant heat projected into the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces at this time have been a sign of wealth, which to some degree is still the idea today.A fireplace is a construction 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 change in heat efficacy, based on the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there's often 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 serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated 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 significant health threat. The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local counties have laws restricting these kinds of fireplaces. Additionally, there are air quality control issues due to the quantity of moisture that they discharge into the room atmosphere, and oxygen detector and carbon monoxide 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 outside of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the home. These fire pits were generally based within a room, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, as opposed to their size.
By the 1800s newest fireplaces were composed of 2 components, the surround and the add. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burnt, and was built of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.AirStone Fireplace Makeover Make Life Lovely Video
Some fireplace units incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency can also be increased by means 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 made from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the air. The ideal method to gauge the output of a fireplace is in case you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first stage the first heat is offered through a big glass while the flame is burning. In this time the construction, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace ideas
