Ancient fire pits were sometimes constructed from the floor, in caves, or at the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits developed into elevated hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where an open flame burnt with all the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it out via a wall or roof. These could be placed against stone walls, rather than taking up the middle of the space, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings handily. They didn't come into general use instantly, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a lengthier area on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the room. Rumford's layout is the basis for modern fireplaces.
Instead it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces now have been a sign of wealth, which to some degree remains the idea today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficacy, depending upon the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
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 risk. The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local businesses have laws restricting these kinds of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control problems due to the amount of moisture they release 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 from the place that's heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally based within a space, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were composed of 2 parts, the surround and the insert. The encircle consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.1000+ ideas about Fireplace Hearth Decor on Pinterest Fireplace hearth, String of lights and Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency is also enhanced with the use of a fireback, a piece of metal that sits behind the fire 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 though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to heat the air. The ideal method to gauge the output of a fireplace is in case you notice you are turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first phase the first heat is offered through a big glass window while the flame is burning. During this time the structure, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.fireplace hearth
