Ancient fire pits were sometimes built from the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated toxic and/or annoying smoke within the house.Fire pits developed into elevated hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open flame burned with the smoke rising to 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.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it out via a wall or roof. These could be placed against rock walls, rather than taking up the middle of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general use immediately, however, as they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting a longer area on very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant heat projected into the space. Rumford's design 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. Instead it relied on simple designs 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 providing quality gems. Stone fireplaces now were a symbol of wealth, which to some degree remains the notion today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficiency, depending on the design.Historically they have been used for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there's frequently a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a significant health threat. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, several states and local counties have laws restricting these types of fireplaces. Additionally, there are air quality control issues because of the amount of moisture that they discharge in 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 from the area that's heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits than modern fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the house. These fire pits were generally centered within a room, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their size.
By the 1800s most new 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 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 add a cozy ambiance into homes.AKDY 36 in.

Some fireplace components include a blower that transfers 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 can also be increased with the use 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 just the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. The best method to gauge the output signal of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly 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 can also be modified by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is provided through a big glass window while the fire is burning. In this time the construction, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Depending on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.wall fireplace heater
