Ancient fire pits were sometimes built from the floor, in caves, or in the center of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of early indoor flame pits was that they generated toxic and/or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it outside via a ceiling or wall. These could be put against stone walls, instead of taking up the center of the space, and this enabled smaller rooms to be heated.Chimneys were devised in northern Europe from 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 also made it possible to put fireplaces in multiple rooms in buildings handily. They did not come into general use immediately, however, as 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 chamber for the fireplace that 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 longer place at the top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and from the construction. The shallow design also improved greatly the amount of radiant heat projected into the space. 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 stone and also deflected unnecessary ornamentation. Instead it depended 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 supplying 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 of brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficiency, depending upon the plan.Historically they were 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 alternative flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the outside of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a significant health risk. The EPA writes"Smoke may smell great, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, several states and local businesses have laws restricting these types of fireplaces. There are also air quality control problems due to the quantity of moisture they release into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed in the place that is 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 visual interest. Early ones were fire pits than modern fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also functioned 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 ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of two parts, the surround and the insert. The surround consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burned, and was built of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance into homes.Sequoia Fireplace Insert, Wood Stove Insert by Kuma Stoves Video
Some fireplace units include a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal that 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 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, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best method to estimate the output of a fireplace is if you detect you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two stages. During the first stage the initial heat is provided through a large glass window while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace insert
