Historical fire pits were sometimes constructed in the floor, in caves, or in the center of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or annoying smoke within the dwelling.Fire pits developed into elevated hearths in buildings, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burned with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it out via a wall or roof. These can be placed against rock walls, rather than taking up the middle of the room, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general use immediately, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer place at the very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the quantity of radiant heat projected into the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and deflected unnecessary ornamentation. Rather 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 placed on supplying quality stone. Stone fireplaces now have been a symbol of wealth, which to a degree is still the idea today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficacy, based on the plan.Historically they were used for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

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 hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A couple of types 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 counties have laws restricting these kinds of fireplaces. Additionally, there are air quality management problems because of the quantity of moisture that they release in the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the place that's heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They were 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 usually centered within a room, allowing more individuals 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 this period were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their size.
By the 1800s most new fireplaces were composed of 2 parts, the surround and the add. The encircle consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was where the fire burned, and was constructed of cast iron often backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into homes.Wood Fireplace Inserts Regency Fireplace Products Video
Some fireplace units include a blower which transports more of the fireplace's heat to the air 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 sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to warm the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to estimate the output of a fireplace is in case you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two phases. During the first phase the initial heat is offered through a large glass window while the fire is burning. During this time period the structure, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.wood fireplace inserts
