Historical fire pits were sometimes constructed from the ground, within caves, or in the middle of a hut or dwelling. Evidence of prehistoric, 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 inside the dwelling.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval 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 snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it out through a ceiling or wall. These could be placed against stone walls, rather than taking up the center 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 possible to give the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general use immediately, however, as they were more expensive to develop 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 that greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer place at the very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the building. The shallow design also improved greatly the quantity of radiant warmth 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 stone and deflected unnecessary ornamentation. Rather it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces now were a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, depending 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 crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, where the casting courses of brick act as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
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 issues because of the amount of moisture that they discharge in the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the place that's heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits than modern fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were generally based within a room, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. 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 had been smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s newest fireplaces were composed of two parts, the surround and the insert. The surround consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance into houses.Dimplex Fieldstone Electric Fireplace Reviews Wayfair 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 with the use of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the atmosphere. The ideal method to estimate the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is provided through a big glass while the flame is burning. In this time the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.dimplex electric fireplace
