Historical fire pits were sometimes built in the floor, in caves, or in the center of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of premature indoor fire pits was that they generated toxic and/or irritating smoke inside the house.Fire pits developed into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where a open flame burned with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it out through a wall or roof. These can be placed against stone walls, instead of taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They did not come into general use immediately, however, as they were more expensive to develop and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting a longer place at the top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the room. Rumford's layout is the basis for modern kitchens.
Rather it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still 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 construction made of brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending on the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses.

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 cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can 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 propane fuel sources. In the United States, some states and local businesses have laws limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control problems because of the quantity of moisture they discharge into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that's heated, and vent all exhaust gasses to the exterior of the structure.

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 famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been smaller, more brightly colored, with a emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were composed of 2 components, the surround and the insert. The encircle consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was where the fire burned, and was built of cast iron frequently backed with ornamental tiles.

Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced with the use 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 manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the air. The best method to estimate the output of a fireplace is if you detect you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof 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 modified by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating process in two phases. During the first stage the initial heat is offered through a large glass while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace insert wood
