Historical fire pits were sometimes built in the floor, within caves, or at the center of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced hazardous or irritating smoke within the house.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically needed a centrally situated hearth, where a open fire burned with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside through a wall or roof. These could be put against rock walls, instead of taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general use instantly, however, since they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a longer place at the very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the foundation for modern kitchens.
Rather it relied on simple layouts 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 gems. Stone fireplaces now were a symbol of prosperity, which to some degree remains the idea today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficiency, based on the design.Historically they were used for heating a dwelling, 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. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that divides up all but the most violent rain. Some 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 could pose a substantial health threat. The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. 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 kinds of fireplaces. There are also air quality management issues because of the quantity of moisture that they release in the room atmosphere, and oxygen detector 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 port all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were generally centered within a space, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most famous fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of two components, the surround as well as the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burnt, and was constructed of cast iron often backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance to houses.Best 25+ Ventless propane fireplace ideas on Pinterest Vent free gas fireplace, Propane Video
Some fireplace units incorporate a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet of metal which 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 complex notion although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to heat the air. The ideal way to estimate the output of a fireplace is if you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating system in two phases. During the first phase the first heat is offered through a big glass 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 phase. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.propane fireplace insert
