Ancient fire pits were sometimes built from the ground, in caves, or in the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced hazardous or annoying smoke inside the dwelling.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where a open flame burnt 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 rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it out via a ceiling or wall. These could be put against rock walls, rather than taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use instantly, however, since they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a lengthier area on top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the quantity of radiant heat projected into the room. Rumford's design is the basis for modern fireplaces.
Instead it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces now were a sign of wealth, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficiency, depending upon the plan.Historically they were used 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 other flue allows exhaust to escape. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.
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 gel, liquid propane, bottled gas or natural gas. In the United States, some states and local businesses have laws limiting these types of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality management problems due to the quantity of moisture that they discharge into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the area that's heated, and port all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits compared to modern fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally based within a room, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most famous fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, instead of their size.
From the 1800s most new fireplaces were made up of 2 parts, 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 fire burnt, and was constructed of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.1000+ ideas about White Fireplace Mantels on Pinterest White Fireplace, Fireplace Mantels and Video
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 space and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace is not, and never was, designed to warm the air. The best method to estimate the output signal of a fireplace is in case you detect you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating system in two stages. During the first phase 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 warmth. This warmth is then equally radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.faux fireplace
