Historical fire pits were sometimes constructed in the floor, within caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated hazardous or irritating smoke inside the dwelling.Fire pits developed into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where an open fire burnt with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out through a wall or roof. These can be put against stone walls, rather than taking up the middle of the space, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to give the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general use immediately, however, as they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased 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 efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer area at the top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant warmth projected to the space. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and deflected unnecessary ornamentation. Rather it depended on simple designs 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 now were a sign of prosperity, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, depending on the plan.Historically they have been used for heating a dwelling, 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. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the casting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the rain. Some 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 could pose a significant 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 flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local counties have laws limiting these kinds of fireplaces. They must be properly sized to the area to be heated. There are also air quality control issues because of the amount of moisture that they discharge into the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the place that is heated, and port all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement 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 functioned as a gathering place inside the house. These fire pits were generally centered within a room, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace designers of the 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 a emphasis on the quality of the substances used in their construction, as opposed to their size.
By the 1800s newest fireplaces were made up of 2 components, the surround as well as the add. The encircle consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into houses.fireplace tile sets SA1969 Blog Video
Some fireplace components include a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased with the use 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 manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best method to estimate the output of a fireplace is if 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 still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two stages. During the first stage the initial heat is offered through a big glass while the fire is burning. During this time the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the next phase. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace set
