Ancient fire pits were sometimes constructed from the ground, within caves, or at the middle of a hut or dwelling. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or annoying smoke within 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 had a centrally located hearth, where a open fire burnt with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it out via a wall or roof. These could be placed against rock walls, instead of taking up the center of the room, and this allowed smaller chambers 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 out. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. They didn't come into general use instantly, however, as they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a lengthier area on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the building. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and deflected unnecessary ornamentation. Instead it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces at this time were a symbol of prosperity, which to a degree remains the idea today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficacy, depending upon the plan.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, in which the projecting 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 out of the outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can 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, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, some states and local businesses have laws restricting these kinds of fireplaces. There are also air quality control issues because of the amount of moisture they release into the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were generally centered within a room, allowing more individuals to collect 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 renowned fireplace designers of the time 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.
From the 1800s newest fireplaces were made up of two parts, the surround and the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.Touchstone 80002 Ivory Contemporary Electric Wall Mounted White Fireplace Video
Some fireplace components include a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to gauge the output of a fireplace is in case you notice you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating system in two phases. During the first phase the initial heat is offered through a big glass window while the flame is burning. In this time the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.modern electric fireplace
