Ancient fire pits were sometimes built in the floor, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The drawback of early indoor fire pits was that they produced hazardous or annoying smoke inside the house.Fire pits grown into raised hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where a open fire burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside via a ceiling or wall. These could be placed against rock walls, instead of taking up the middle of the room, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general use immediately, however, as they were expensive to develop and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer place at the top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's design is the foundation for modern fireplaces.
Instead it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces at this time have been a symbol of prosperity, which to some degree is still the notion today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, based on the plan.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, where the casting courses of brick act as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a significant health risk. The EPA writes"Smoke may smell good, but it's not good for you.Kinds 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 few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the USA, some states and local counties have laws restricting these types of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality control issues because of the quantity of moisture they release into the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed in the area that's heated, and vent all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits compared to modern fireplaces.

Many flaws were found in early fireplace designs. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with a emphasis on the level 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 insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into homes.1000+ ideas about Gel Fireplace on Pinterest Wall Mount, Electric Fireplaces and Ethanol Fireplace Video
Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased 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 made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace isn't, and never was, intended to heat the atmosphere. The ideal method to estimate the output signal of a fireplace is in case you notice you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two stages. During the first phase the initial heat is offered through a large glass while the flame is burning. During this time the structure, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.ventless fireplace
