Historical fire pits were sometimes built in the ground, in caves, or at the center of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or irritating smoke inside 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 flame burned with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out through a ceiling or wall. These could be put against stone walls, instead of taking up the middle of the room, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings conveniently. They did not 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 chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a longer area at the top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing up the smoke and from the building. The shallow design also improved greatly the quantity of radiant warmth projected to the room. Rumford's layout is the foundation for modern fireplaces.
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 at this time were a sign of wealth, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficiency, depending upon the plan.Historically they were 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 other flue allows exhaust to escape. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, 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 act as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, several states and local counties have laws limiting these types of fireplaces. They must be properly sized to the area to be heated. There are also air quality control issues because of the amount of moisture they release into the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the place that is heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits compared to contemporary fireplaces.

They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the materials used in their construction, as opposed to their size.
By the 1800s most new fireplaces were made up of two components, the surround and the add. The surround consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was where the fire burned, and was built of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.Electric Fireplace TV Stands Corner Heater Antique Firebox Fireplaces 47 In Hold eBay Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency is also enhanced by means 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 made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best method to estimate the output of a fireplace is if you detect you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first phase the initial heat is offered through a big glass window while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.corner electric fireplace tv stand
