Ancient fire pits were sometimes built in the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/or irritating smoke within the house.Fire pits developed into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open flame burned with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it outside through a ceiling or wall. These can be put against stone walls, rather than taking up the center of the space, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to put 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 enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer area on top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of the construction. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and also deflected unnecessary ornamentation. 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 still placed on providing quality gems. Stone fireplaces at this time have been a sign of wealth, which to a degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficiency, based upon the design.Historically they were utilized 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 other flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, 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 atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the area that's heated, and vent all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were generally based within a room, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of 2 components, the surround and the add. The surround consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burnt, and was constructed of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into houses.Drake Mechanical Gas Fireplaces Video
Some fireplace components include a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also 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 manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the atmosphere. The best method to gauge the output signal of a fireplace is if you detect you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two stages. During the first stage the initial heat is provided through a large glass window while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second stage. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.gas fireplaces
