Historical fire pits were sometimes built in the floor, in caves, or at the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits developed into elevated hearths in buildings, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where a open flame burnt 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 wouldn't enter.

Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it out via a ceiling or wall. These can be put against rock walls, instead of taking up the middle of the room, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings handily. They did not come into general use instantly, however, as they were more expensive to build and maintain.

Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a lengthier area at the very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and from the building. The shallow design also improved greatly the quantity of radiant warmth projected to the room. Rumford's layout is the basis for modern fireplaces.

The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it relied on simple designs with small 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 at this time have been a symbol of wealth, which to a degree is still the notion today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, depending on the design.

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. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, where the casting courses of brick act as a drip route 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 far greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.

Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.

In the United States, some states and local businesses have laws restricting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control problems due to the quantity of moisture that they release into the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the place that is heated, and port all exhaust gasses to the outside of the structure.

AccessoriesA wide assortment of accessories are used with fireplaces, ranging between countries, regions, and historical periods. For the inside, common in recent Western cultures comprise grates, fireguards, log boxes, andirons, bark baskets, along with fire dogs, all of 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 utilized to capture and re-radiate heat, to safeguard the back of the fireplace, and as decoration. Fenders are low metallic frames placed in front of the fireplace to include embers, soot and ashes.

Over time, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They have been used for heat 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 room, allowing more people to gather around it.

It was smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, as opposed to their size.

From the 1800s newest fireplaces were composed of two components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite.

Some fireplace components incorporate a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to heat the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The ideal 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 score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is offered through a large glass window while the flame is burning. During this time the structure, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the second phase. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.napoleon fireplace
