Historical fire pits were sometimes constructed in the ground, within caves, or in the center of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or irritating smoke within the house.Fire pits grown into raised hearths in buildings, but ventilation 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 rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it out via a wall or roof. These can 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 issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings handily. They didn't come into general usage 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. 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 basement and venting a lengthier place on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been 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 design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple designs with small 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 stone. Stone fireplaces at this time have been a symbol of wealth, which to some degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficacy, depending on the design.Historically they have been used for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, 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 are fueled by either liquid propane or natural gas. They are totally sealed in the place that's heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits than modern fireplaces.

It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, instead of their size.
By the 1800s newest fireplaces were composed of 2 components, the surround as well as the add. The surround comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance to houses.Amazon.com: Polyfiber Electric Fireplace with 41quot; Mantle: Home Kitchen Video
Some fireplace components include a blower which transports more of the fireplace's heat to the air via convection, resulting in 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 fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, designed to heat the atmosphere. The best method to gauge the output signal of a fireplace is in case you notice you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating process in two phases. During the first phase the first heat is offered through a big glass window while the fire is burning. During this time period the structure, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.amazon electric fireplace
