Ancient fire pits were sometimes constructed in the floor, within caves, or in the center of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of early indoor flame pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where a open fire burnt with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it out through a wall or roof. These could be put against stone walls, rather than taking up the center of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings handily. They didn't come into general usage 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 chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier place at the top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and out of the building. The shallow design improved greatly the amount of radiant heat projected into the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and also deflected unnecessary ornamentation. Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces now were a sign of prosperity, which to some degree remains the idea today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending upon the plan.Historically they have been used for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, that divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass fire 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 electric fireplaces.
In the United States, several states and local businesses have laws restricting these types of fireplaces. They must be suitably sized to the area to be heated. There are also air quality management problems due to the quantity of moisture that they release in the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been 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.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits compared to modern 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 house. These fire pits were usually centered within a room, allowing more people to collect around it.

Many defects were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that 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, instead of their dimensions.
By the 1800s newest fireplaces were composed of 2 parts, the surround and the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance into homes.IHP Superior DRL3000 Direct Vent Linear Gas Fireplace Video
Some fireplace components incorporate a blower which 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 is also increased with the use of a fireback, a piece of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be made from stainless steel. Efficiency is a complex concept 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. The ideal way to gauge the output of a fireplace is if you detect you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the first heat is provided through a big glass while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next stage. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.linear gas fireplace
