Ancient fire pits were sometimes built from the floor, in caves, or in the middle of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or irritating smoke within the dwelling.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The great hall typically had a centrally located hearth, where an open flame burned with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable 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 ceiling or wall. These can be put against stone walls, rather than taking up the middle of the space, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem 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 multiple rooms in buildings handily. They didn't come into general use immediately, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a lengthier area on very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing up the smoke and from the building. The shallow design improved greatly the amount of radiant warmth projected to the space. Rumford's layout is the foundation for modern fireplaces.
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 placed on providing quality stone. Stone fireplaces now have been a symbol of prosperity, which to a degree remains the notion today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, based on 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.

On the exterior there's frequently a corbeled brick crown, where the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the cap or crown.

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 gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws limiting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control issues because of the quantity of moisture they release into the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally centered within a room, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of 2 parts, the surround as well as the add. The surround comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.15 Gorgeous Painted Brick Fireplaces HGTVs Decorating Design Blog HGTV Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency is also 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 made 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 atmosphere. An open fireplace is not, and never was, designed to heat the atmosphere. The best way to estimate 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 though have an efficiency rating of at least 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 large as 80% in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the first heat is offered through a big glass while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.painted fireplace
