Ancient fire pits were sometimes built from the ground, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated toxic and/or annoying smoke inside the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where an open flame burnt with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it outside through a ceiling or wall. These could be put against stone walls, rather than taking up the center of the room, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general use immediately, however, since they were expensive to develop 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 improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a longer place on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing up the smoke and from the construction. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's design is the basis for modern kitchens.
Instead it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces now were a sign of wealth, which to a degree remains the idea today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a room. Modern fireplaces change in heat efficacy, depending upon the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there's frequently a corbeled brick crown, in which the projecting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain in 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 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 can pose a significant health threat. The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesManufactured fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws restricting these types of fireplaces. There are also air quality management problems because of the amount of moisture that they discharge into the room atmosphere, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the place that's heated, and port all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were more fire pits compared to 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 centered within a room, allowing more people to gather around it.

Many flaws were found in early fireplace designs. The most famous fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of 2 components, the surround as well as the add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance into homes.free standing wood fireplaces Stove Free Standing Wood Burning Stoves Stoves Video
Some fireplace components include a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be made from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm the air. The ideal method to gauge the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the first heat is provided through a large glass while the fire is burning. In this time the structure, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Based on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.free standing fireplace
