Historical fire pits were sometimes built from the ground, in caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or annoying smoke within the house.Fire pits developed into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open fire burnt with all the smoke climbing into 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.

Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it out via a ceiling or wall. These could be put against rock walls, instead of taking up the middle 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 reliably venting smoke out. They made it feasible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage immediately, however, as they were expensive to develop and maintain.

Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a longer area at the top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant heat projected into the room. Rumford's design is the foundation for modern kitchens.

The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and deflected unnecessary ornamentation. Rather it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces at this time were a symbol of wealth, which to a degree remains the idea today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficiency, 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 foundation, 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 chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which 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 out of the exterior of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which divides up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.

Types of fireplacesArtificial 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.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.

In the United States, several states and local businesses have laws restricting these types of fireplaces. There are also air quality control issues because of the quantity of moisture they discharge in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the place that's heated, and port all exhaust gasses into the outside of the structure.

AccessoriesFor the interior, common in recent Western civilizations include grates, fireguards, log boxes, andirons, pellet baskets, and fire puppies, all which cradle fuel and accelerate burning. A grate (or flame grate) is a framework, usually of iron bars, to maintain fuel to your fire. Heavy metal firebacks are sometimes utilized to capture and re-radiate warmth, to protect the rear of the fireplace, and as decoration. Fenders are low metal frames set in front of the fireplace to contain embers, soot and ashes. For fireplace tending, tools comprise pokers, bellows, tongs, shovels, brushes and instrument stands. Other wider accessories can include log baskets, companion sets, coal buckets, cabinet accessories and much more.

Over time, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits compared to contemporary fireplaces. They were used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were usually based within a room, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. The most famous fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their dimensions.

From the 1800s most new fireplaces were made up of 2 parts, the surround and the add. The encircle comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burned, and was built of cast iron often backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to houses.

Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace is not, and never was, intended to heat the air. The ideal way to estimate the output 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, 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 can also be modified by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80% in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two phases. During the first phase the first heat is offered through a big glass window while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.outdoor gas fireplace
