Ancient fire pits were sometimes constructed in the ground, within caves, or in the center of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or annoying smoke inside the house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open flame burnt with the smoke climbing into 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 during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it outside via a ceiling or wall. These can be placed against stone walls, rather than taking up the center of the room, and this allowed smaller chambers to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it possible 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 usage instantly, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting a lengthier place on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing up the smoke and out of the construction. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's layout is the basis for modern kitchens.
Rather it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they were used for heating a home, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape.

On the exterior there is often 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 outside of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which soaks up all but the most violent rain. Some 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 different studies, fireplaces can pose a substantial health risk. The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesManufactured fireplaces are made with 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.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the USA, some states and local businesses have laws limiting these types of fireplaces. Additionally, there are air quality control issues due to the amount of moisture they release into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the place that is heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally centered within a space, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround and the add. The encircle consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.Ceiling Mounted Fireplaces 9 coolest ceiling fireplace designs Captivatist Video
Some fireplace units include a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made 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 effect of heating of the air. An open fireplace is not, and never was, designed to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best way to gauge the output of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating system in two stages. During the first phase the initial heat is offered through a big glass while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.hanging fireplace
