Historical fire pits were sometimes constructed in the ground, in caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The drawback of premature indoor fire pits was that they generated hazardous or annoying smoke within the house.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The great hall typically had a centrally located hearth, where an open flame burnt with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it out through a wall or roof. These could be put against stone walls, rather than taking up the middle of the room, and this enabled smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general use instantly, however, since they were expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a longer area on top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design improved greatly the amount of radiant heat projected into the room. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple layouts with little unnecessary ornamentation. In 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 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 made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, depending upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there's frequently a corbeled brick crown, where the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain at the chimney is a much greater difficulty 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 integrated into the crown or cap.
The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesManufactured fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
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 gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems because of the amount of moisture that they release into 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 vent all exhaust gasses into the outside of the structure.

Over time, 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 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 space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It was smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s most new fireplaces were made up of two components, the surround as well as the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The insert was where the fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance into houses.48 best Fireplace Ideas images on Pinterest Fireplace ideas, Fire places and Gas fireplace inserts Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced with the use 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 are also manufactured from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. The ideal method to estimate the output signal of a fireplace is if you notice you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two stages. During the first phase the first heat is provided through a large glass while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace inserts gas
