Ancient fire pits were sometimes constructed in the ground, within caves, or at the center of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced toxic and/or irritating smoke inside the dwelling.Fire pits developed into elevated 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 burnt with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it outside through a wall or roof. These could be placed against rock walls, instead of taking up the center of the space, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to give the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. They did not come into general use immediately, however, since they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting out a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design improved greatly the quantity of radiant warmth projected to the room. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Rather it depended on simple designs with little unnecessary ornamentation. From 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 have been a symbol of prosperity, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficacy, based on the design.Historically they have been 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.

On the exterior there's 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 serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not great for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.
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, several states and local counties have laws limiting these kinds of fireplaces. Additionally, there are air quality control problems because of the amount of moisture that they release in the room air, and oxygen detector and carbon monoxide sensors are security 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 port all exhaust gasses to the exterior of the structure.

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

Many defects were found in early fireplace designs. The most famous fireplace performers of the period 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 size.
From the 1800s most new fireplaces were composed of 2 parts, the surround and the add. The encircle consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was where the fire burned, and was built of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance to houses.Hussong Manufacturing and American Flame Recall Three Gas Fireplaces, Fireplace Inserts Due to Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a piece of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complicated 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, designed to heat the air. The ideal way to gauge the output of a fireplace is if you notice you are turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80% 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 phase the first heat is provided through a large glass while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace gas inserts
