Historical fire pits were sometimes constructed from the floor, in caves, or in the center of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burned with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it outside via a ceiling or wall. These could be placed against stone walls, instead of taking up the middle of the space, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe from 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 also made it feasible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, since they were expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer area on very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant heat projected to the room. Rumford's design is the foundation for modern fireplaces.
Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to 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 some degree remains the idea today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficacy, depending on the plan.Historically they have been used 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 base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the projecting 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 out of the outside of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, some states and local counties have laws restricting these kinds of fireplaces. They must be properly sized to the area to be heated. There are also air quality management issues due to the amount of moisture that they release in 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 totally sealed from the area that's heated, and vent all exhaust gasses to the outside of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally based within a room, allowing more people to gather around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. 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 most new fireplaces were made up of 2 parts, the surround and the insert. The surround consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into homes.25+ best ideas about Corner fireplace mantels on Pinterest Stone fireplace mantles, Rustic Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also increased 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 can also be manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the atmosphere. The best method to estimate the output signal of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example 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 large as 80% in heating the air. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two phases. During the first phase the first heat is offered through a big glass window while the flame is burning. During this time period the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second stage. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplace ideas
