Ancient fire pits were sometimes built in the floor, within caves, or at 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 produced hazardous or irritating smoke within the house.Fire pits grown into raised hearths in structures, but venting smoke depended on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where an open fire burnt with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it out through a wall or roof. These can be placed against rock walls, instead of taking up the center of the space, and this enabled 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 reliably venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage immediately, however, since they were 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. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier place on top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing the smoke up and out of the construction. The shallow design improved greatly the quantity of radiant heat projected to the space. Rumford's design is the basis for modern kitchens.
Instead it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality gems. Stone fireplaces now were 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 contain a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficacy, depending upon the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for laundry and domestic 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, in which the projecting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, that divides up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, several states and local counties have laws restricting these types of fireplaces. They must be suitably sized to the area to be heated. There are also air quality management problems due to the amount of moisture they discharge in the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the place that is heated, and port all exhaust gasses into the outside of the structure.

Over time, the intent behind 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 heat on chilly days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were usually based within a room, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of the time were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It was smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, instead of their size.
From the 1800s most new fireplaces were made up of 2 components, the surround as well as the add. The surround comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was fire burned, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.XL Large 1500W 35quot;x22quot; Electric Fireplace Wall Mount Heater w/ Remote Adjustable eBay Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced with the use of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to heat the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best way to gauge the output signal of a fireplace is in case you notice you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is offered through a large glass window while the flame is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.wall fireplace
