Historical fire pits were sometimes constructed in the ground, in caves, or in the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated hazardous or irritating smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open fire burned with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it outside through a wall or roof. These can be put against rock walls, rather than taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were devised 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 provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. 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 venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a lengthier area at the very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the building. The shallow design improved greatly the amount of radiant warmth projected to the space. Rumford's design is the foundation for modern fireplaces.
Instead it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces at this time were a symbol of wealth, which to a degree remains the idea 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 space. Modern fireplaces vary in heat efficacy, based on the plan.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might 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 chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
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 substantial health risk. The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A couple of 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 gas 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 businesses have laws limiting these types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control issues due to the quantity of moisture they release into the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the area that's heated, and port all exhaust gasses into 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 compared to modern fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were generally based within a space, allowing more individuals to gather around it.

Many defects were found in ancient fireplace designs. The most famous fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, as opposed to their size.
By the 1800s most new fireplaces were composed of 2 components, the surround as well as the add. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to homes.UniFlame Venetian Bronze 5Piece Fireplace Tool Set with Heavy Crook HandlesF1657 The Home Depot Video
Some fireplace components include a blower that 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 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 made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace is not, and never was, intended to heat the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal way to gauge the output of a fireplace is if you notice you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating process in two phases. During the first stage the initial heat is provided through a big glass window while the flame is burning. During this time period the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.fireplace tool set
