Historical fire pits were sometimes built from the floor, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open flame burned with the smoke climbing into the vent 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.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out through a wall or roof. These could be put against rock walls, instead of taking up the center of the space, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, as they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room 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 longer area on very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the quantity of radiant heat projected to the room. Rumford's layout is the basis for modern fireplaces.
Rather it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces now were a sign of prosperity, which to a degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficacy, based upon the plan.Historically they were utilized for heating a home, 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 (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that soaks up all but the rain. A few chimneys have a spark arrestor incorporated 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 good, but it is not great for you.Types of fireplacesManufactured fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.
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 management issues because of the amount of moisture they release in the room atmosphere, and oxygen detector 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 place that's heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They were used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were usually centered within a space, allowing more people to gather around it.

Many flaws were found in early fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s newest fireplaces were made up of 2 components, the surround and the add. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was fire burned, 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 bring a cozy ambiance into homes.24+ Outdoor Fireplace Designs, Ideas Design Trends Premium PSD, Vector Downloads Video
Some fireplace units incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a sheet of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated 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, designed to heat the air. The ideal way to estimate the output signal of a fireplace is if you detect you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. 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 altered by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two phases. During the first stage the first heat is provided through a large glass window while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Depending on temperatures 1 to two daily firings are enough to guarantee a constant room temperature.diy outdoor fireplace
