Ancient fire pits were sometimes built from the ground, in caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or annoying smoke within the house.Fire pits developed into elevated hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open flame burned with 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 invented to stop smoke from spreading through a room and vent it outside via a wall or roof. These can be placed against stone walls, rather than taking up the middle of the room, and this enabled 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 outside. They made it feasible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, as they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer place on top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and from the building. The shallow design also improved greatly the quantity of radiant heat projected to the space. Rumford's design is the foundation for modern kitchens.
Rather it depended on simple layouts with small unnecessary ornamentation. From 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 sign of wealth, which to a degree remains the idea today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there's 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 in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that 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 can pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not good for you.Types 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 electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, several states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality management issues due to the quantity of moisture they discharge into the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the place that is heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were more fire pits than contemporary fireplaces. They have been used for heat on cold days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were generally centered within a space, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. The most famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were composed of two components, the surround and the insert. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was where the fire burnt, and was constructed 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 to houses.Elec Fireplace Walmart.com Video
Some fireplace components include a blower which 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 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 can also be manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best method to gauge the output signal of a fireplace is in case you detect you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two stages. During the first phase the first heat is offered through a big glass while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.electric fireplace walmart
