Ancient fire pits were sometimes built from the floor, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or annoying smoke inside the house.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burned with 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 rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it outside through a wall or roof. These can be placed against stone walls, rather than taking up the middle of the space, and this enabled smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings handily. They didn't come into general use immediately, however, since they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a lengthier place at the very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected to the room. Rumford's layout is the foundation for modern fireplaces.
Instead it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces now have been a symbol of wealth, which to a degree remains the idea today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficacy, depending upon the design.Historically they have been utilized for heating a home, 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 casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local counties have laws restricting these types of fireplaces. Additionally, there are air quality control problems due to the amount of moisture that they release in the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the area that's heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits compared to modern fireplaces. They were used for heat on cold days and nights, as well as 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 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 designers of this time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly lit, with a emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were made up of 2 parts, the surround as well as the insert. The surround consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.Dimplex Martindale 63Inch Electric Fireplace With Purifire Espresso GDS301150E : Gas Log Guys Video
Some fireplace components include a blower that transports 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 increased by means of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal method to estimate the output 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, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating system in two stages. During the first phase the initial heat is provided through a large glass while the fire is burning. During this time period the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.dimplex electric fireplaces
