Ancient fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they produced hazardous or irritating smoke within the dwelling.Fire pits grown into raised hearths in structures, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where an open fire burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it out through a wall or roof. These could be placed against stone walls, rather than taking up the center of the room, and this allowed 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 out. They made it feasible to provide the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings handily. They did not come into general use immediately, however, as they were more expensive to build and maintain.The 18th century saw two important 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 cellar and venting out a lengthier place at the top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the building. The shallow design also improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the foundation for modern fireplaces.
Rather it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a sign of prosperity, which to a degree remains the notion today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficacy, based upon the plan.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, 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 chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the casting 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 out of the outside of the chimney; rain at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric 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. In the USA, several states and local counties have laws restricting these types of fireplaces. There are also air quality management problems due to the quantity of moisture that they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the area that's heated, and vent all exhaust gasses into 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 than modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were usually based within a room, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of two parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burned, and was built of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance to houses.Home Decorators Collection Ravensdale 48 in.

Some fireplace units incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal that sits behind the flame 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 concept though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the atmosphere. The ideal method to gauge the output signal of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two phases. During the first stage the initial heat is provided through a large glass window while the fire is burning. During this time period the construction, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.electric fireplace tv stand
