Historical fire pits were sometimes constructed from the ground, within caves, or at the middle 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 house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where an open fire burnt with the smoke climbing into the port 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.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it outside through a wall or roof. These could be placed against stone walls, instead of taking up the center of the space, and this allowed smaller rooms 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 possible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings handily. They did not 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 that greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a longer area at the top. At the later 18th century, Count Rumford designed 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 into the room. Rumford's design is the basis for modern kitchens.
Instead it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces at this time were a symbol of prosperity, which to some 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 they create and for heating a space. Modern fireplaces change in heat efficiency, based on the design.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic 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 foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

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

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, some states and local businesses have laws restricting these kinds of fireplaces. There are also air quality control issues due to the amount of moisture that they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the place that is heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were fire pits than contemporary fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were usually centered within a room, allowing more people to gather around it.

Many defects were found in early fireplace designs. The most famous fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It had been smaller, more brightly lit, with a emphasis on the quality of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of two parts, the surround and the insert. The encircle consisted of the mantlepiece and sides supports, typically 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 warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance into houses.Wood Fireplace Mantels Fredricksburg Custom Mantels MantelCraft Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced 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 though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the air. An open fireplace isn't, and never was, designed to heat the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best way to gauge the output of a fireplace is in case you detect you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These altered fireplaces are usually 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 fire is burning. In this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Depending on temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace surrounds
