Ancient fire pits were sometimes built in the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits grown into elevated hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open fire burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it out via a ceiling or wall. These can be placed against stone walls, instead of taking up the middle of the room, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general usage instantly, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer place on top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant heat projected to the space. Rumford's design is the basis for modern fireplaces.
Instead it relied on simple designs with small unnecessary ornamentation. From 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 now were a sign of prosperity, which to some degree is still the idea today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficacy, 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 alternative flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which soaks up all but the rain. Some 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. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local counties have laws restricting these types of fireplaces. There are also air quality control problems because of the amount of moisture they discharge into the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the place that is heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were fire pits compared to contemporary fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were usually centered within a room, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly lit, with a emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were composed of two components, the surround and the add. The surround consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance into homes.Walker Edison Corner Fireplace TV Stand for 50 inch Screens Black W48FPCRBL Video
Some fireplace units 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 decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a sheet of metal that 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 concept though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal method 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 still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two phases. During the first stage the first heat is provided 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 evenly radiated for several hours during the next stage. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.black fireplace tv stand
