Ancient fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or annoying smoke within the house.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open flame burned with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it outside through a wall or roof. These could be placed against rock walls, instead of taking up the center of the space, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were expensive to develop and maintain.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 enhanced the airflow by pulling air from a basement and venting a lengthier area at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's design is the basis for modern kitchens.
Instead it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces at this time have been a sign of prosperity, which to some degree is still the idea today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficiency, based upon the design.Historically they have been used for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations like 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 is not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, some states and local businesses have laws restricting these kinds of fireplaces. There are also air quality control problems due to the quantity of moisture that they release into the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the area that's heated, and port all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits than modern fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place within the home. These fire pits were usually based within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace performers 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 lit, with an emphasis on the quality of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of two parts, the surround as well as the insert. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance into homes.Shop ACHLA Designs 5Piece Fireplace Tool Set at Lowes.com Video
Some fireplace components incorporate 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 is also increased by means of a fireback, a piece of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to warm the air. The ideal way to gauge 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 cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating process in two stages. During the first phase the first heat is provided through a big glass window while the fire is burning. During this time the structure, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the second stage. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace tool set
