Historical fire pits were sometimes built in the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced hazardous or irritating smoke within the dwelling.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Also 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 can be put against rock walls, rather than taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general usage 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 airflow and venting system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a longer place at the very 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 out of the construction. The shallow design also improved greatly the amount of radiant heat projected to the space. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now have been a sign of wealth, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficacy, depending on the plan.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there is frequently a corbeled brick crown, where the projecting courses of brick act as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could 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, electrical 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. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality management issues due to the quantity of moisture they discharge in 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 totally sealed in the area that's heated, and port all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were usually centered within a room, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, as opposed to their size.
From the 1800s newest fireplaces were composed of two parts, the surround as well as the add. The surround consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burnt, and was built 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 homes.High Efficiency Fireplace Home Energy Pros Forum Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also increased with the use of a fireback, a sheet of metal that sits behind the fire 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 concept although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace isn't, and never was, intended to heat the air. The best method 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 still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two phases. During the first phase the initial heat is provided through a large glass while the flame is burning. During this time period the structure, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace damper
