Ancient fire pits were sometimes built from the ground, in caves, or at the center of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor fire pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits developed into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open fire burned with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.

Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it outside through a wall or roof. These could be placed against stone walls, instead of taking up the center of the room, and this enabled 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 possible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, since they were more expensive to develop and maintain.

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

Rather it depended on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces now have been a sign of prosperity, which to a degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, depending upon the design.

Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, 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 act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.

Kinds of fireplacesManufactured fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical 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 United States, several states and local counties have laws restricting these kinds of fireplaces. There are also air quality control problems due to the quantity of moisture they discharge into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the place that's heated, and vent all exhaust gasses to the outside of the structure.

AccessoriesA wide assortment of accessories are used with fireplaces, ranging between states, regions, and historical periods. For the interior, common in recent Western cultures include grates, fireguards, log boxes, andirons, bark baskets, along with fire dogs, all of which cradle gas and quicken burning. A grate (or fire grate) is a framework, usually of iron bars, to retain fuel to your fire. Heavy metal firebacks are sometimes utilized to catch and re-radiate warmth, to protect the rear of the fireplace, and as decoration. Fenders are low metal frames placed before the fireplace to include embers, soot and ashes.

As time passes, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for heat on cold days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were generally centered within a space, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. The most famous fireplace performers of this time were the Adam Brothers.

From the 1800s most new fireplaces were made up of two parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was fire burned, and was built of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to homes.

Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency is also enhanced with the use of a fireback, a piece of metal which 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 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, intended to heat the atmosphere. The best way to gauge the output signal of a fireplace is if you notice you're turning the thermostat up or down.

Most older fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the first heat is provided through a large glass while the fire is burning. In this time the structure, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.direct vent fireplace
