Historical fire pits were sometimes built in the floor, in caves, or at the center of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they generated hazardous or annoying smoke inside the house.Fire pits grown into elevated hearths in structures, but venting smoke relied 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 vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it out via a wall or roof. These could be placed against rock walls, rather than taking up the center of the room, and this enabled smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general use instantly, however, since they were more expensive to develop and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a lengthier place at the very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the foundation for modern kitchens.
Instead it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces at this time were a symbol of prosperity, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending upon the plan.Historically they were utilized for heating a home, 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 laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell good, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
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 United States, some states and local counties have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems because of the quantity of moisture they discharge in the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the place that is heated, and vent all exhaust gasses into the outside of the structure.

Over time, the intent behind 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 heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were generally centered within a space, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of two parts, the surround as well as the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance to homes.Rushmore 40 Inch TruFlame Direct Vent Fireplace Fines Gas Video
Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also enhanced 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 can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal method to gauge the output signal of a fireplace is if you detect you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating process 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, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.direct vent fireplace
