Ancient fire pits were sometimes constructed in the floor, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor fire pits was that they generated hazardous or annoying smoke within the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open flame burned with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it out through a wall or roof. These can be put against stone walls, instead of 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 problem of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings handily. They didn't come into general usage immediately, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting a lengthier place on top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of the construction. The shallow design also improved greatly the amount of radiant heat projected into the space. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it relied on simple designs with little unnecessary ornamentation. In 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 now have been a sign of wealth, which to some degree is still the notion today.A fireplace is a construction 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 vary in heat efficiency, depending upon the plan.Historically they were utilized for heating a dwelling, 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 might 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 bar, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

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

In the USA, 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 in the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the place that's heated, and port all exhaust gasses to the exterior of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the house. These fire pits were generally based within a room, allowing more individuals 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 kind of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, instead of their size.
From the 1800s newest fireplaces were made up of two components, the surround and the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance into homes.Regency Gas Insert Horizon HRI6E Gas Insert The Fireplace Club Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. The ideal method to gauge the output signal of a fireplace is if you notice you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two stages. During the first phase the initial heat is provided through a big glass while the flame is burning. In this time the construction, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.regency fireplace
