Ancient fire pits were sometimes built in the ground, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or annoying smoke inside 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 needed a centrally located hearth, where an open flame burned with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it out through a ceiling or wall. These can be placed against rock walls, rather than taking up the middle of the room, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use instantly, 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 which greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer place at the very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing the smoke up and from the building. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's design is the foundation for modern kitchens.
Instead it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces at this time have been a sign of prosperity, which to a degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, based on the design.Historically they have been utilized for heating a dwelling, 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 crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the casting 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 out of the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that soaks 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 good, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws limiting these types of fireplaces. There are also air quality management problems because of the amount of moisture that they release into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the area that's heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were fire pits than contemporary fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were usually centered within a room, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were composed of two parts, the surround and the add. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance to houses.Southern Enterprises Kyledale Faux Brick Electric Fireplace TV Stand Walmart.com Video
Some fireplace components include a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be increased with the use of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal way to gauge the output signal 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 may also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two phases. During the first phase the initial heat is provided through a large glass window while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the heat. 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 sufficient to ensure a constant room temperature.fireplace tv stand walmart
