Ancient fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or irritating smoke inside the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where an open flame burnt 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 snow and rain wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it out via a ceiling or wall. These could be put against rock walls, instead of 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 largely fixed the issue of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general use instantly, however, as they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a lengthier area at the top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and from the construction. The shallow design improved greatly the amount of radiant heat projected into the space. Rumford's layout is the foundation for modern fireplaces.
Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces at this time were a symbol of wealth, which to a degree remains the notion today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficiency, depending on the plan.Historically they have been utilized for heating a home, 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 foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently 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 hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
Organizations like 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 is not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical 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 USA, several states and local businesses have laws limiting these types of fireplaces. There are also air quality control issues because of the quantity of moisture they discharge in the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the area that is heated, and port all exhaust gasses to the outside of the structure.

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

Many defects were found in early fireplace designs. The most renowned 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 lit, with a emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of two components, the surround as well as the insert. The surround comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was where the fire burnt, and was constructed of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance to houses.Fireplace Designs Modern Fireplace Ideas Custom Fireplaces Wood, NG, BioFuel Video
Some fireplace units incorporate 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 by means of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm the air. The best method to gauge the output signal of a fireplace is in case you notice you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating system in two stages. During the first stage the initial heat is provided through a big glass while the fire is burning. During this time period the structure, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the second stage. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace design
