Ancient fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or irritating smoke within the house.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burnt with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it out via a ceiling or wall. These can be put against stone 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 mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general usage immediately, 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 room for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a lengthier place at the top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing up the smoke and from the construction. The shallow design also improved greatly the amount of radiant heat projected to the room. Rumford's layout is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and deflected unnecessary ornamentation. Rather it relied on simple designs 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 at this time were a symbol of prosperity, which to a degree is still the notion today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficacy, based on the plan.Historically they were utilized 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 crane (used in laundry and kitchen 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's frequently a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which divides 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 substantial health risk. The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
In the USA, several states and local counties have laws limiting these kinds of fireplaces. Additionally, there are air quality control problems due to the quantity of moisture they discharge into the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the place that is heated, and vent all exhaust gasses into the exterior of the structure.

It had been smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, as opposed to their size.
By the 1800s newest fireplaces were composed of 2 parts, the surround and the insert. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to homes.Home Decorators Collection Avondale Grove 70 in.

Some fireplace units incorporate a blower that 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 can also be increased with the use of a fireback, a sheet of metal which 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 notion though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the atmosphere. The best method to estimate the output signal of a fireplace is if you notice you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may 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 air. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating process in two phases. During the first phase the initial heat is provided through a large glass while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace tv stands
