Ancient fire pits were sometimes constructed from the ground, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or irritating smoke inside the house.Fire pits grown into raised hearths in structures, but venting smoke relied on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with all the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it outside via a wall or roof. These can be put against rock walls, instead of taking up the middle of the room, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to give the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage immediately, however, as they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a lengthier place on very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing up the smoke and from the building. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's layout is the foundation for modern fireplaces.
Instead it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces now were a sign of wealth, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, based upon the design.Historically they have been utilized 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 bar, 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 projecting courses of brick act as a drip course 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 greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either 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.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these types of fireplaces. They must be suitably sized to the area to be heated. Additionally, there are air quality management problems because of the amount of moisture they release in the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and vent all exhaust gasses to the exterior of the structure.

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 contemporary fireplaces. They have been used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the house. These fire pits were generally centered within a room, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. The most famous fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly colored, with a emphasis on the level 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 as well as the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to houses.Sunjoy LOF117PSTA Stylus Fireplace Lowes Canada Video
Some fireplace components include a blower which transfers 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 is also increased by means of a fireback, a piece of metal that 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 complex concept although with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the atmosphere. The best method to gauge the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most older 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 such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as large 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 phase the initial heat is offered through a large glass window while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.lowes fireplace
