Ancient fire pits were sometimes built in the floor, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced hazardous or irritating smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burned with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it out through a wall or roof. These can be placed against rock walls, instead of taking up the center of the room, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace that 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 on top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and also deflected unnecessary ornamentation. Instead it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces now were a sign of wealth, which to some degree remains the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they were utilized for heating a home, 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.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick act 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 at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, several states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality management issues because of the quantity of moisture that they release into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in 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 requirement to one of interest. Early ones were fire pits than contemporary fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the house. These fire pits were usually centered within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of this period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were composed of two parts, the surround and the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burned, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance into homes.Electric Fireplace Oak, Walmart YouTube Video
Some fireplace components include a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased with the use of a fireback, a piece of metal that 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 notion though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. The best method to gauge the output of a fireplace is in case you notice you're 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 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the initial heat is provided through a large glass window while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.walmart fireplace
