Ancient fire pits were sometimes constructed from the ground, in caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced hazardous or annoying smoke within the house.Fire pits grown into raised hearths in buildings, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where a open flame burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it out through a ceiling or wall. These can be put against stone walls, instead of taking up the middle of the space, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general usage instantly, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a lengthier area on very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's design is the basis for modern kitchens.
Instead 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 still placed on supplying quality gems. Stone fireplaces at this time were a sign of prosperity, which to a degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might 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 bar, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often 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 cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the cap or crown.
Organizations like 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.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass flame 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, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the USA, several states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems because of the amount of moisture they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses to 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 have been used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were usually based within a room, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. The most famous fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, as opposed to their size.
By the 1800s most new fireplaces were composed of two parts, the surround and the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to houses.Home Decorators Collection Avondale Grove 59 in.

Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece of metal that sits behind the fire 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 efficacy tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to warm the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best way to gauge the output of a fireplace is if you notice you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually 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 big glass while the fire is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace tv stands
