Historical fire pits were sometimes constructed from the ground, in caves, or at the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or annoying smoke within the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open fire burnt with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside via a wall or roof. These could be placed against rock walls, instead of taking up the center of the room, and this allowed 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 faithfully venting smoke outside. They made it possible to give the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings handily. They did not come into general usage immediately, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. 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 enhanced the airflow by pulling air from a basement and venting a lengthier place on very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and also deflected unnecessary ornamentation. Instead it depended 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 gems. Stone fireplaces at this time were a sign of prosperity, which to a degree remains the notion today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficiency, based on the plan.Historically they have been utilized for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there is frequently a corbeled brick crown, where the casting courses of brick act as a drip course 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 in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made with 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 USA, several states and local counties have laws limiting these kinds of fireplaces. They must be properly sized to the area to be heated. There are also air quality control problems because of the quantity of moisture that they release in the room atmosphere, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the area that's heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They were used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally based within a room, allowing more people 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 performers of this time were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were made up of 2 parts, the surround and the add. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burned, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.Southern Enterprises Creston Cherry Electric Fireplace Media Console Fireplaces at Hayneedle Video
Some fireplace components incorporate a blower which transfers 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 is also enhanced 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 made from cast iron, but can also be made from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the air. An open fireplace is not, and never was, intended to heat the air. The ideal way to estimate the output of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have 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 designed to burn cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two stages. During the first phase the initial heat is offered through a big glass window while the flame is burning. During this time period the structure, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the second stage. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.media fireplace
