Ancient fire pits were sometimes constructed from the ground, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated toxic and/or irritating smoke inside the house.Fire pits developed into elevated hearths in structures, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open flame burnt with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside through a ceiling or wall. These could be put against rock walls, rather than taking up the center of the space, and this enabled smaller chambers 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 outside. They made it possible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general use immediately, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier area at the top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing the smoke up and out of the building. The shallow design also improved greatly the quantity of radiant warmth projected to the room. Rumford's design is the foundation for modern fireplaces.
Instead it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces now have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they have been 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, where the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the United States, some states and local businesses have laws restricting these kinds of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality control issues due to the amount of moisture that they release into the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been 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 outside of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more 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 within the home. These fire pits were generally based within a room, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design which 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.
By 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 decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance into homes.Napoleon 60quot; Allure Wall Mount Electric Fireplace NEFL60FH Napoleon Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced by means of a fireback, a piece 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 manufactured from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace is not, and never was, intended to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal way to estimate the output signal of a fireplace is in case you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is offered through a big glass while the fire is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.electric wall fireplace
