Ancient fire pits were sometimes built in the floor, within caves, or in the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or irritating smoke inside the house.Fire pits grown into elevated hearths in buildings, but venting smoke relied on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open flame burned with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it outside through a wall or roof. These can be placed against rock walls, instead of taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use immediately, however, since they were expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer area at the very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and from the construction. The shallow design improved greatly the amount of radiant warmth projected into the space. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and deflected unnecessary ornamentation. Rather it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces now have been a sign of prosperity, which to some degree remains the notion today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficiency, based on the plan.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where 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 out of the outside of the chimney; rain at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell good, but it's not good for you.Kinds of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws limiting these kinds of fireplaces. There are also air quality control problems due to the quantity of moisture they release into the room air, and oxygen sensor and carbon dioxide 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 to the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were generally based within a room, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. Along 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 style of fireplace design that was used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their size.
From the 1800s most new fireplaces were made up of two components, the surround as well as the add. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burned, and was built of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.Three Posts Boston Faux Stone Corner Electric Fireplace Reviews Wayfair Video
Some fireplace units incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced with the use of a fireback, a sheet of metal which 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 concept although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, and never was, intended to heat the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best way to gauge the output of a fireplace is in case you detect you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating system in two phases. During the first phase the initial heat is offered through a big glass while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.stone electric fireplace
