Historical fire pits were sometimes constructed in the floor, within caves, or at the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of early indoor flame pits was that they generated hazardous or irritating smoke within the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where a open fire burned with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it outside via a ceiling or wall. These can be placed against stone walls, instead of taking up the middle of the room, and this allowed 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 reliably venting smoke outside. They made it possible to give the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. They didn't come into general use immediately, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a lengthier area at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing the smoke up and out of the building. The shallow design improved greatly the amount of radiant heat projected to the room. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock and also deflected unnecessary ornamentation. Rather it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces at this time have been a symbol of prosperity, which to a degree is still the idea today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficacy, depending on the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which soaks up all but the 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 propane fuel sources. In the United States, several states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality control problems due to the quantity of moisture that they discharge in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that is heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were usually based within a space, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design that 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 dimensions.
From the 1800s newest fireplaces were made up of 2 parts, the surround and the insert. The surround consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance to houses.New resident, can get pilot lit, but fireplace wont turn off when switched on DoItYourself Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced with the use 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 can also be manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. The best way to estimate the output signal of a fireplace is if you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively 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 altered by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as large 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 stages. During the first phase the initial heat is provided through a large glass window while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the next stage. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.how to turn on gas fireplace
