Historical fire pits were sometimes constructed from the floor, in caves, or at the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor flame pits was that they generated toxic and/or annoying smoke inside the house.Fire pits developed into raised hearths in buildings, but venting smoke depended on open windows or holes in roofs. The great hall typically needed a centrally located hearth, where a open fire burned with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it out via a ceiling or wall. These could be put against stone walls, rather than taking up the middle of the room, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use instantly, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a longer place at the very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and from the building. The shallow design improved greatly the quantity of radiant warmth projected into the room. Rumford's design is the basis for modern kitchens.
Instead it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces at this time have been a symbol of prosperity, which to some degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, based on the plan.Historically they have been used for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently 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 hood, cap, or shroud functions to keep rainwater out of the exterior 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, which divides 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 great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, some states and local businesses have laws restricting these types of fireplaces. There are also air quality management problems due to the amount of moisture that they discharge into the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the place that is heated, and vent all exhaust gasses into 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 than contemporary fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also functioned as a gathering place within the home. These fire pits were generally based within a room, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, as opposed to their size.
From the 1800s most new fireplaces were composed of two parts, the surround and the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was where the fire burnt, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance into homes.Dimplex Electric Fireplaces » Mantels » Products » Noah Media Console/Mantel Electric Fireplace Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal that sits behind the fire 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 complicated notion though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace is not, and never was, intended to warm the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best way to gauge the output signal of a fireplace is in case you notice you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have 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 large as 80% in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the initial heat is offered through a big glass while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.electric fireplaces
