Ancient fire pits were sometimes constructed in the floor, within caves, or at the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor flame pits was that they generated hazardous or irritating smoke within the dwelling.Fire pits developed 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 an open flame burned with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it out via a ceiling or wall. These could be placed against rock walls, instead of taking up the middle of the room, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem 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 conveniently. They didn't come into general use instantly, however, as they were more expensive to build and maintain.The 18th century saw two major 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. He also improved the airflow by pulling air from a basement and venting out a longer place at the very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the basis for modern fireplaces.
Rather it relied on simple layouts with small 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 gems. Stone fireplaces now were a symbol of wealth, which to a degree is still the notion today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficacy, based on the design.Historically they were utilized for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, 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 throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, where the casting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which divides up all but the rain. A few 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 could pose a significant health risk. The EPA writes"Smoke may smell good, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.
In the USA, several states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality control problems due to the quantity of moisture they discharge into the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the area that is heated, and port all exhaust gasses into the exterior of the structure.

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

Many defects were found in early fireplace designs. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were made up of two components, the surround and the insert. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was fire burned, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance into homes.Inglenook Fire Poker Sets. Brush Shovel Tongs.

Some fireplace components include 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 can also be increased by means 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 can also be made from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, designed to heat the atmosphere. The ideal method to estimate 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 rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the first heat is provided through a big glass window while the fire is burning. During this time period the structure, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the next stage. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.fireplace poker set
