Ancient fire pits were sometimes built from the floor, within caves, or at the middle of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of early indoor flame pits was that they produced hazardous or irritating smoke within the house.Fire pits grown into elevated hearths in structures, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open flame burnt 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 snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside via a wall or roof. These can be placed against stone walls, instead of taking up the middle of the room, and this allowed smaller chambers to be heated.Chimneys were devised 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 made it possible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use immediately, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow 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 basement and venting out a lengthier area on top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the amount of radiant heat projected to the space. Rumford's layout is the foundation for modern kitchens.
Instead it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces now were a sign of prosperity, which to some degree is still the idea today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the casting courses of brick function as a drip course 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 in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. 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 limiting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management issues due to the amount of moisture that they discharge into the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and port all exhaust gasses to the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally based within a space, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace performers of this time 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 level of the substances used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of 2 components, the surround as well as the add. The encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was where the fire burnt, and was constructed of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.Fireplaces Outdoor Kitchens LanChester Grill Hearth Video
Some fireplace units 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 decrease heating load. Fireplace efficiency can also be 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 made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated concept though 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 heat the atmosphere. The best way to gauge the output of a fireplace is if you detect you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two phases. During the first phase the initial heat is provided through a large glass while the fire is burning. In this time the structure, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the next stage. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplaces
