Ancient fire pits were sometimes built in the ground, within caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where a open fire burned with all 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 devised to prevent smoke from dispersing a room and vent it out via a wall or roof. These can be placed against stone walls, rather than taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that 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 place at the top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the construction. The shallow design improved greatly the quantity of radiant heat projected into the space. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and deflected unnecessary ornamentation. Instead it relied on simple layouts with small 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 gems. Stone fireplaces at this time have been a sign of wealth, which to a degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, depending upon the plan.Historically they were used for heating a dwelling, 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's often a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell great, 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 either gas or wood or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the USA, some states and local businesses have laws restricting these kinds of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality control issues because of the amount of moisture that they discharge into the room atmosphere, 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's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally based within a space, allowing more people to gather around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were composed of two parts, the surround and the add. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was where the fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Fireplace TV Stands Electric Fireplaces The Home Depot Video
Some fireplace units include a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece of metal which sits behind the fire 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 complex concept although with open hearth fireplaces. Most efficiency 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 radiant heater, and has done so since the 15th century. The best method to estimate the output of a fireplace is in case you detect you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn much cleaner and may 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 system in two stages. During the first stage the initial heat is offered through a large glass window while the fire is burning. In this time the structure, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.home depot fireplace
