Historical fire pits were sometimes built from the floor, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of premature indoor flame pits was that they produced toxic and/or annoying smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable 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 an area and vent it outside via a wall or roof. These can be placed against rock walls, instead of taking up the center of the room, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, however, as they were more expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a lengthier area on top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant warmth projected into the space. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and also deflected unnecessary ornamentation. Instead it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time have been a sign of wealth, which to some degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, based on the design.Historically they have been used 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. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain at the chimney is a much greater 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 incorporated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, some states and local businesses have laws limiting these types of fireplaces. Additionally, there are air quality management issues due to the amount of moisture they discharge in the room atmosphere, 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 from the area that is heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits than modern fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were generally centered within a space, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s newest fireplaces were made up of two components, the surround and the insert. The encircle consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was fire burnt, and was built of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to homes.1850W Log Burner Flame Effect Electric Fireplace Stove Heater £51.99 : Oypla Stocking the Video
Some fireplace units include a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best method to gauge the output of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two phases. During the first phase the first heat is offered through a big glass 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 stage. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.electric fireplace heater
