Ancient fire pits were sometimes built in the ground, in caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or irritating smoke inside the house.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 throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside through a ceiling or wall. These can be put against rock walls, instead of taking up the middle of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully 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 conveniently. They did not come into general usage immediately, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a lengthier place on top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant warmth projected to the space. Rumford's layout is the basis for modern kitchens.
Rather it depended on simple layouts with small unnecessary ornamentation. From 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 wealth, which to a degree remains the notion today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficacy, based on the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health threat. The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
In the United States, several states and local counties have laws limiting these types of fireplaces. There are also air quality management issues because of the quantity of moisture that they release into the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the area that's heated, and port all exhaust gasses into the outside of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits compared to contemporary fireplaces.

Many flaws were found in early 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 has been used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround and the insert. The surround comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The insert was where the fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance into homes.Holly Martin™ Weatherford Convertible Gel Fireplace 200937, Fireplaces at Sportsmans Guide 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 space and a lower heating load. Fireplace efficiency is also enhanced with the use 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 manufactured from stainless steel. Efficiency is a complicated concept though 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 warm the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best method to gauge the output of a fireplace is in case you notice you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80% in heating the air. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the first heat is provided through a large glass while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.gel fireplace
