Ancient fire pits were sometimes built in the floor, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or annoying smoke inside the dwelling.Fire pits developed into elevated hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where an open fire burned with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out via a ceiling or wall. These could be put against rock walls, instead of taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it possible to give the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general usage instantly, however, since they were more expensive to build 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 that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting a longer area on very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's design is the basis for modern fireplaces.
Rather it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces at this time were a sign of wealth, which to a degree is still the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficacy, depending on the design.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry 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'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 exterior walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesManufactured fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces could 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 gas fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either 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. Additionally, there are air quality management problems due to the quantity of moisture they discharge into the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the place that is heated, and port all exhaust gasses to the outside 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 contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were generally centered within a space, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. The most famous fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s most new fireplaces were composed of 2 parts, the surround and the insert. The encircle consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was fire burned, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to homes.1000+ images about Fireplace Design Ideas, Indoor on Pinterest Mantels, Mantles and Indoor Video
Some fireplace units incorporate a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, and never was, designed to heat the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal method to estimate the output signal of a fireplace is in case you notice you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively 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 altered by inserting special heavy fireboxes developed to burn much 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, allowing an efficient heating system in two phases. During the first stage the first heat is offered through a large glass window while the flame is burning. During this time period the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to two daily firings are enough to ensure a constant room temperature.indoor fireplace
