Ancient fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. 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 venting smoke relied on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside via a ceiling or wall. These could be placed against rock walls, rather than taking up the middle of the room, and this allowed smaller chambers to be heated.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 feasible to give the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, as they were expensive to develop and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a lengthier place at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and from the building. The shallow design improved greatly the amount of radiant warmth projected to the space. Rumford's design is the foundation for modern kitchens.
Instead it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces now were a sign of prosperity, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, depending upon the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick function as a drip route to keep rainwater from running down the outside 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 problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the cap or crown.

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 kinds of fireplaces. They must be suitably sized to the area to be heated. There are also air quality management issues due to the amount of moisture they release into the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were fire pits than modern fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally centered within a room, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were composed of 2 components, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burnt, and was constructed of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance into houses.CASTLECREEK™ Electric quot;Stonequot; Fireplace Heater 227153, Fireplaces at Sportsmans Guide Video
Some fireplace units incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced by means of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. 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 ideal way to gauge the output signal of a fireplace is in case you notice you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is provided through a big glass window while the fire is burning. During this time period the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the second phase. Masonry fireplaces with no glass fire window just provide heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.electric heater fireplace
