Ancient fire pits were sometimes built in the floor, 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 produced toxic and/or annoying smoke within the house.Fire pits developed into raised hearths in structures, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.

Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it out via a wall or roof. These can be placed against stone walls, instead of taking up the center of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage instantly, however, as they were more expensive to develop and maintain.

Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a lengthier area on top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design also improved greatly the quantity of radiant heat projected to the room. Rumford's design is the basis for modern fireplaces.

The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Rather it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces at this time were a symbol of prosperity, which to a degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficiency, depending on the design.

Historically they have been 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 other flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the exterior 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 divides up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.

Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not good for you.

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 electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, some states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management issues because of the quantity of moisture that they discharge in the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety 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 exterior of the structure.

AccessoriesFor the inside, common in recent Western cultures comprise grates, fireguards, log boxes, andirons, bark baskets, and fire puppies, all which cradle fuel and accelerate burning. A grate (or flame grate) is a framework, usually of iron bars, to retain fuel to your fire. Heavy metal firebacks are occasionally used to capture and re-radiate heat, to protect the rear of the fireplace, and as decoration. Fenders are low metallic frames placed in front of the fireplace to contain embers, soot and ash. For fireplace tending, tools include pokers, bellows, tongs, shovels, brushes and instrument stands.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to modern fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally centered within a space, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating 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 had been smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their dimensions.

From the 1800s most new fireplaces were made up of two parts, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance into homes.

Some fireplace units include a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a sheet of metal which 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 notion though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best method to gauge the output of a fireplace is if you detect you're turning the thermostat up or down.

Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified 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 fire is burning. In this time period the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.dimplex electric fireplace insert
