Historical fire pits were sometimes built from the floor, within caves, or in the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor flame pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits developed into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally located 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 covered so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out via a wall or roof. These can be placed against stone walls, instead of taking up the middle of the space, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use 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 venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer area at the very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing up the smoke and out of the construction. The shallow design improved greatly the amount of radiant heat projected into the space. Rumford's design is the basis for modern kitchens.
Rather it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces at this time have been a sign of prosperity, which to a degree remains the notion today.A fireplace is a construction made of 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 efficacy, based upon the plan.Historically they were utilized for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, 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 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 much larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that divides up all but the most violent rain. Some 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 can pose a significant health risk. The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local counties have laws restricting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control issues due to the quantity of moisture that they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that's heated, and port all exhaust gasses to the exterior of the structure.

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

Many defects were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of this period 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 level of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of two components, the surround and the insert. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.Housewarmer Fireplace Mantel Surround with Shelf eBay Video
Some fireplace components include a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased 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 are also manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. The best method to estimate the output signal of a fireplace is in case you detect you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning 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 modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two phases. During the first phase the initial heat is provided through a large glass while the flame is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Based on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace mantels
