Historical fire pits were sometimes constructed in the floor, within caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they generated hazardous or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open flame burned with all the smoke rising to the vent in the roof. Louvers were developed during 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 invented to prevent smoke from spreading through a room and vent it out via a ceiling or wall. These can be placed against stone walls, instead of taking up the middle of the room, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings handily. They didn't come into general usage instantly, however, since they were expensive to build and maintain.

In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a lengthier area on very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's design is the basis for modern kitchens.

Instead it relied 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 placed on supplying quality stone. Stone fireplaces at this time were a symbol of prosperity, which to a degree remains the idea today.A fireplace is a construction 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 plan.

Historically they were used 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 alternative flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, in which the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

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

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the United States, some states and local businesses have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality management issues because of the quantity of moisture that they release in the room atmosphere, and oxygen sensor 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 is heated, and port all exhaust gasses to the exterior of the structure.

AccessoriesA wide range of accessories are used with fireplaces, ranging between states, regions, and historical periods. For the inside, common in recent Western cultures include grates, fireguards, log boxes, andirons, bark baskets, and fire dogs, all of 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 catch and re-radiate warmth, to protect the back of the fireplace, and as decoration. Fenders are low metal frames placed before the fireplace to contain embers, soot and ash. For fireplace tending, tools include pokers, bellows, tongs, shovels, brushes and tool stands. Other wider accessories can consist of log baskets, companion sets, coal buckets, cabinet accessories and more.

Over time, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were more fire pits compared to contemporary 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 home. These fire pits were usually based within a room, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, as opposed to their size.

By the 1800s newest fireplaces were composed of two components, the surround and the add. The surround consisted of the mantlepiece and sides affirms, typically in wood, marble or granite.

Some fireplace units incorporate a blower which transports 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 can also be increased 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 made from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal way to estimate the output signal of a fireplace is if you detect you're turning the thermostat down or up.

Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two stages. During the first stage the initial heat is provided through a big glass while the fire is burning. In this time the structure, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace damper
