Historical fire pits were sometimes constructed in the floor, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or irritating smoke inside the house.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burnt with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it out through a ceiling or wall. These can be placed against rock walls, instead of taking up the middle of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue 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 conveniently. They didn't come into general use instantly, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a lengthier place on very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing the smoke up and from the building. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces at this time were a symbol of prosperity, which to some degree remains the notion today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, depending on the plan.Historically they have been used 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 casting 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 in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that divides up all but the rain. A few 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 risk. The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical 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. In the USA, several states and local counties have laws limiting these types of fireplaces. There are also air quality control problems because of the amount of moisture they discharge in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that is heated, and port all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were usually centered within a space, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of two components, the surround as well as 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 often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance to houses.SpectraFire 36 in.

Some fireplace units include a blower that transfers 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 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 made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the air. The ideal method to estimate the output signal of a fireplace is in case you notice you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the first heat is offered through a big glass while the flame is burning. During this time period the structure, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.electric fireplace inserts
