Historical fire pits were sometimes built in the floor, in caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits developed into elevated hearths in structures, but venting smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with 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 snow and rain would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it outside through a ceiling or wall. These can be placed against stone walls, instead of taking up the middle 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 reliably venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings handily. They did not come into general use immediately, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting out a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing up the smoke and from the building. The shallow design improved greatly the amount of radiant warmth projected into the space. Rumford's design is the basis for modern kitchens.
Instead it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now have been a symbol of prosperity, which to a degree is still the idea today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, depending on the plan.Historically they were utilized 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 foundation, 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 chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick act 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 in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a significant health threat. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A couple of 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 United States, some states and local counties have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems because of the amount of moisture that they discharge into the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the place that is heated, and port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits than modern fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were usually based within a space, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. The most famous fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s most new fireplaces were composed of 2 components, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was 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 thought to add a cozy ambiance to homes.Amazon.com SEI Sicilian Harvest Electric Fireplace, Mahogany Gel Fuel Fireplaces Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased with the use of a fireback, a piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the atmosphere. The best method to gauge the output of a fireplace is in case you detect you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes developed to burn cleaner and may 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 offered through a big glass window while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.amazon electric fireplace
