Ancient fire pits were sometimes built from the floor, within caves, or in the center 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 developed into raised hearths in buildings, but ventilation 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 during the Middle Ages to allow 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 spreading through an area and vent it outside via a wall or roof. These could be put against stone walls, rather than taking up the middle of the space, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a longer place at the very top. At the later 18th century, Count Rumford made a fireplace with 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 warmth projected into the space. Rumford's layout is the foundation for modern kitchens.
Instead it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where 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 notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficiency, based on the design.Historically they were used for heating a home, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, where 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 outside of the chimney; rain at the chimney is a much larger difficulty 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 integrated 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 with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A couple of kinds 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 businesses have laws limiting these types of fireplaces. Additionally, there are air quality management issues due to the amount of moisture that they release into the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and port all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were usually centered within a room, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that was 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.
By the 1800s newest fireplaces were composed of two components, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance to houses.Decorating Ideas for Fireplace Mantels and Walls DIY Video
Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a piece 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 although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the air. An open fireplace is not, and never was, intended to heat the atmosphere. The ideal way to estimate the output signal of a fireplace is in case you notice you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two stages. During the first phase the initial heat is provided through a big glass window while the flame is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the second phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace mantel decorating ideas
