Historical fire pits were sometimes constructed from the ground, in caves, or in the center of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor fire pits was that they produced toxic and/or annoying smoke within the house.Fire pits developed into elevated hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where an open flame burned with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it outside through a wall or roof. These can be put against rock walls, rather than taking up the middle of the space, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings handily. They did not 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 airflow and venting system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer place on top. In the later 18th century, Count Rumford made 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 heat projected to the room. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and deflected unnecessary ornamentation. 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 supplying quality stone. Stone fireplaces now have been a sign of wealth, which to a degree remains the notion today.A fireplace is a construction 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 room. Modern fireplaces change in heat efficiency, depending on the plan.Historically they have been used for heating a home, 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 (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from 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 rain. A few chimneys have a spark arrestor integrated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass fire 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, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, some states and local businesses have laws restricting these types of fireplaces. They must be suitably sized to the area to be heated. Additionally, there are air quality management issues due to the amount of moisture that they discharge into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the place that is heated, and port all exhaust gasses to the outside of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits than modern fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were generally based within a room, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. The most renowned fireplace designers of this 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 level of the substances used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were composed of two parts, the surround and the add. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Superb Prices Deals Cast Tec Majestic Integra Fireplace Insert Free Delivery Video
Some fireplace components include a blower that transports 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 increased with the use 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 manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. The best way to estimate the output of a fireplace is if you notice you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes designed 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, 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. In this time period the construction, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.majestic fireplace
