Ancient fire pits were sometimes built in the floor, in caves, or in the center of a hut or dwelling. Evidence of ancient, 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 within the house.Fire pits developed into elevated hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open flame burnt with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it out through a wall or roof. These could be placed against stone walls, instead of taking up the center of the space, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and 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 develop and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a longer place on very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that has been better at drawing up the smoke and from the building. The shallow design improved greatly the quantity of radiant heat projected into the space. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces now were a symbol of wealth, which to a degree is still the idea today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently 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 exterior of the chimney; rain in the chimney is a far greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it is 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 electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws restricting these kinds of fireplaces. There are also air quality control problems because of the quantity of moisture they release 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 totally sealed in the area that is heated, and port all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were generally centered within a space, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of 2 components, the surround as well as the insert. The surround comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was fire burnt, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance to homes.Dimplex Farley 47 in.

Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced by means 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 complicated concept although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. The best method to gauge the output signal of a fireplace is if you detect you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the initial heat is provided through a big glass window while the fire is burning. In this time period the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.home depot electric fireplace
