Historical fire pits were sometimes constructed in the ground, within caves, or at the center of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated hazardous or annoying smoke inside the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open flame burnt with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.

Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it outside through a wall or roof. These can be placed against rock walls, instead of taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, as they were expensive to build and maintain.

Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting a longer area on very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the construction. The shallow design also improved greatly the amount of radiant heat projected to the room. Rumford's design is the foundation for modern kitchens.

Rather it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to 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 is still 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 they create and also for heating a room. Modern fireplaces vary in heat efficacy, depending on the design.

Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace might 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, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal 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.

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

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws limiting these types of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality control issues because of the amount of moisture they release in the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the area that is heated, and vent all exhaust gasses into the exterior of the structure.

AccessoriesFor the interior, common in recent Western cultures include grates, fireguards, log boxes, andirons, bark baskets, and fire dogs, all which cradle fuel and accelerate burning. A grate (or fire grate) is a frame, usually of iron bars, to retain fuel for a fire. Heavy metallic firebacks are sometimes used to capture and re-radiate warmth, to protect the back of the fireplace, and as decoration. Fenders are low metallic frames placed in front of the fireplace to include embers, soot and ash. For fireplace tending, tools comprise pokers, bellows, tongs, shovels, brushes and instrument stands. Other wider accessories may consist of log baskets, companion sets, coal buckets, cabinet accessories and more.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits compared to contemporary fireplaces. They were 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 generally centered within a space, allowing more people to gather around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly colored, with a emphasis on the level of the substances used in their construction, as opposed to their dimensions.

From the 1800s newest fireplaces were composed of 2 parts, the surround and the insert. The encircle consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was where the fire burned, and was constructed of cast iron frequently backed with ornamental tiles.

Some fireplace components include a blower that transports more of the fireplace's heat to the atmosphere 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 sheet of metal that sits behind the flame 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 complicated notion although with open hearth fireplaces. Most efficiency tests consider only the impact 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 signal of a fireplace is in case you notice you're turning the thermostat down or up.

Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof 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 developed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two phases. During the first phase the first heat is provided through a big 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 next phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.wood fireplace
