Ancient fire pits were sometimes built in the ground, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced toxic and/or irritating smoke within the house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open fire burned with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside through a wall or roof. These could be put against rock walls, rather than taking up the center of the space, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use immediately, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting out a longer place on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still 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 used for the relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficiency, based on the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater from the exterior of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, some states and local businesses have laws restricting these types of fireplaces. There are also air quality management issues due to the quantity of moisture that they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and port all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were usually centered within a space, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of the time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround as well as the add. The encircle consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burnt, 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 add a cozy ambiance into homes.Wrought Iron South Fork 4Tool Fireplace Set with Natural Broom from TimelessWroughtIron.com Video
Some fireplace units incorporate a blower which transfers 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 is also increased by means of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the air. An open fireplace is not, and never was, designed to warm the atmosphere. The best method to gauge the output signal of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can 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 modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two phases. During the first stage the initial heat is provided through a big glass window while the fire is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the second phase. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace tool set
