Ancient fire pits were sometimes built in the floor, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or irritating smoke inside the house.Fire pits developed into raised hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burned with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.

Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out through a ceiling or wall. These can be put against rock walls, instead of taking up the center of the room, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general usage immediately, however, since they were expensive to develop and maintain.

In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer place on very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the amount of radiant heat projected into the room. Rumford's layout is the basis for modern fireplaces.

Instead it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces now have been a symbol of prosperity, which to some degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, based upon the plan.

Historically they have been utilized for heating a home, 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 crane (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick function as a drip course 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 far larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.

Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.

Heavy metallic firebacks are occasionally utilized to capture and re-radiate heat, to protect the rear of the fireplace, and as decoration. Fenders are low metal frames placed before the fireplace to contain embers, soot and ashes.

Some fireplace components include a blower which transfers 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 fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to estimate the output signal of a fireplace is if you detect you are turning the thermostat up or down.

Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two phases. During the first phase the first heat is offered through a large glass while the fire is burning. In this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.direct vent fireplace
