Historical fire pits were sometimes built from the ground, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced toxic and/or irritating smoke inside the house.Fire pits developed into raised hearths in buildings, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside via a ceiling or wall. These can 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 in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to give the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, 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 chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer area at the top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and from the building. The shallow design improved greatly the amount of radiant warmth projected to the space. Rumford's design is the foundation for modern kitchens.
Rather it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now have been a sign of prosperity, which to a degree is still the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, based on the plan.Historically they were used 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.

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 cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated 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 with sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.
In the United States, several states and local counties have laws limiting these types of fireplaces. They must be properly sized to the area to be heated. There are also air quality management problems due to the amount of moisture that they discharge into the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely 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 necessity to one of interest. Early ones were fire pits than contemporary 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 flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of two components, the surround and the add. The encircle comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance into houses.Dimplex Kendal 63Inch Electric Fireplace With Purifire Parchment GDS321164P : Fireplace Video
Some fireplace components incorporate a blower which transfers 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 increased by means of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. The best method to estimate the output of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the initial heat is provided through a big glass while the flame is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. 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 its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.electric fireplaces
