Ancient fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where an open flame burned with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it outside via a ceiling or wall. These could be put against stone walls, instead of taking up the center of the room, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general usage immediately, however, since they were expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting a longer place at the top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the basis for modern kitchens.
Rather it depended on simple layouts with small unnecessary ornamentation. From 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 now were a symbol of wealth, which to some degree remains the idea today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficiency, depending upon the design.Historically they have been 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 alternative flue allows exhaust to escape.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell good, but it's not great for you.Types of fireplacesManufactured fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.
In the USA, several states and local businesses have laws limiting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control problems because of the quantity of moisture they release in the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the place that is heated, and vent all exhaust gasses to the outside 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 have been used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally based within a space, allowing more people to gather around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating 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 quality of the materials used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were composed of 2 parts, the surround and the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance to houses.Napoleon 72quot; Allure Wall Mount Electric Fireplace NEFL72FH Napoleon Video
Some fireplace units include a blower that transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease 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 are also manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. A fireplace with a fireback is a toaster, and has done so as 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 comparatively low efficiency score. 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 can also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the initial heat is offered through a big glass window while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Depending on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplaces electric
