Historical fire pits were sometimes constructed in the ground, in caves, or in the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced hazardous or irritating smoke inside the house.Fire pits grown into raised hearths in buildings, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burnt with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside via a ceiling or wall. These could be put against rock walls, instead of taking up the center of the room, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe in 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 put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. The 18th century saw two important 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. He also enhanced the airflow by pulling air from a basement and venting a longer area at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and out of 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. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces now have been a sign of prosperity, which to some degree remains the notion today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, depending on 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 casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain at the chimney is a far larger 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 integrated into the crown or cap.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, some states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality control problems because of the quantity of moisture they release in the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the place that's heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were usually centered within a space, allowing more people to collect around it.

Many defects 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 period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were made up of two components, the surround as well as the insert. The surround comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was where the fire burnt, and was constructed 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 to homes.Large Room Infrared Quartz Electric Fireplace Heater Honey Oak Finish w/ Remote eBay Video
Some fireplace units 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 lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a piece of metal which sits behind the flame 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 although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to estimate the output of a fireplace is if you notice you're 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 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the first 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 warmth is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.electric heater fireplace
