Ancient fire pits were sometimes built in the floor, in caves, or in the center of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of early indoor flame pits was that they generated hazardous or irritating smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burned with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside 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 mostly fixed the issue of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings handily. They did not come into general usage 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 venting and airflow system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a longer area at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's layout is the basis for modern fireplaces.
Instead it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces now were a sign of prosperity, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficiency, depending upon the design.Historically they have been 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 other flue allows exhaust to escape. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house 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, in which the casting courses of brick act as a drip course 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 in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either wood or gas 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.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. 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. They need to be properly sized to the area to be heated. There are also air quality control problems because of the amount of moisture that they discharge in the room air, and oxygen detector and carbon dioxide 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's heated, and port all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits than 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 within the house. These fire pits were generally based within a space, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design that 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 dimensions.
From the 1800s most new fireplaces were made up of 2 components, the surround as well as the insert. The encircle comprised 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 often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance into homes.XL Large 35quot;x22quot; 1500W Adjustable Heater Electric Wall Mount Fireplace Elegant eBay Video
Some fireplace components include a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal which sits behind the flame 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 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 method to estimate the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two phases. During the first stage the first heat is offered through a big glass window while the flame is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace heaters
