Ancient fire pits were sometimes built in the ground, 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 premature indoor flame pits was that they generated toxic and/or irritating smoke inside the house.Fire pits developed into elevated hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where an open fire burnt with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside via a wall or roof. These can be placed against rock walls, rather than taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, as they were more expensive to build 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 chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a longer place at the top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and deflected unnecessary ornamentation. Rather it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality stone. Stone fireplaces now have been a sign of prosperity, which to a degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed 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 efficacy, depending on the design.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen 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's frequently a corbeled brick crown, where the projecting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for either gas or wood 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.
In the United States, several states and local counties have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. There are also air quality control problems because of the amount of moisture they discharge in the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the place that is heated, and port all exhaust gasses to the outside of the structure.

Over time, 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 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 designers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were made up of 2 parts, the surround as well as the add. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burned, and was built of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.Dimplex 26quot; MultiFire XHD PlugIn Electric Insert Logs XHD26L Dimplex Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a piece of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to gauge the output of a fireplace is if you detect you are 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 can also be modified by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating system in two phases. During the first stage the first heat is offered through a large glass while the flame is burning. In this time period the structure, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.dimplex electric fireplace insert
