Ancient fire pits were sometimes constructed in the floor, within caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits grown into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where a open fire burned with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable 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 a room and vent it out via a wall or roof. These can be placed 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 mostly fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings handily. They didn't come into general use immediately, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a lengthier area on top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing up the smoke and out of the building. The shallow design also improved greatly the quantity of radiant warmth projected into the space. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional 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 into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality stone. Stone fireplaces now were a sign of wealth, which to a 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 its relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they were 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. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws restricting these kinds of fireplaces. There are also air quality control problems due to the quantity of moisture that they release into the room air, and oxygen sensor and carbon monoxide sensors are safety 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 into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits than modern fireplaces.

Many flaws were found in ancient fireplace designs. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, as opposed to their size.
By the 1800s newest fireplaces were composed of 2 components, the surround and the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burned, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.Montigo H38DFST See Through Fireplace Natural Choice Heating Video
Some fireplace units include a blower that transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet of metal which sits behind the flame 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 effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. The best way to estimate the output signal of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 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 cleaner and can reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two stages. During the first stage the initial heat is offered through a big glass while the fire is burning. In this time the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.montigo fireplace
