Historical fire pits were sometimes built from the floor, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor fire pits was that they generated hazardous or irritating smoke inside the dwelling.Fire pits developed into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where an open fire burned with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it outside through a ceiling or wall. These can be placed against rock walls, rather than taking up the center of the room, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings handily. They didn't come into general use instantly, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a longer place on 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 from the building. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and also deflected unnecessary ornamentation. Rather it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces now were a sign of prosperity, which to a degree is still the idea today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficacy, depending upon the design.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there is often a corbeled brick crown, where the casting courses of brick function as a drip route 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 much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
In the United States, some states and local counties have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control issues due to the amount of moisture they release into the room atmosphere, and oxygen detector and carbon dioxide sensors are security 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 vent all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits than modern fireplaces.

By the 1800s newest fireplaces were composed of two components, the surround and the add. The encircle consisted of the mantlepiece and sides affirms, usually in wood, marble or granite.

Some fireplace components include a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to 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 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 is not, and never was, designed to warm the air. The ideal way to gauge the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the initial heat is offered through a large glass while the fire is burning. In this time the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace tile
