Historical fire pits were sometimes constructed in the floor, in caves, or at the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burned with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it out via a wall or roof. These can be put against stone walls, rather than taking up the center of the room, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings conveniently. They did not come into general use instantly, however, as 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 important 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 lengthier area on top. At 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 room. Rumford's layout is the foundation for modern fireplaces.
Rather it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces at this time have been a sign of wealth, which to a degree is still the notion today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, based on the design.Historically they have been 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 other flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

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 outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that soaks up all but the most violent rain. A few 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 various studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, some states and local businesses have laws restricting these kinds of fireplaces. There are also air quality control problems because of the amount of moisture that they release into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the place that's heated, and port all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits compared to modern fireplaces. They have been used for heat on cold days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were generally based within a room, allowing more people to collect around it.

Many defects were found in early fireplace designs. The most renowned fireplace designers of the period 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 an emphasis on the level of the materials used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were made up of two parts, the surround and the insert. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance into homes.Home Decorators Collection Charles Mill 46 in.

Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease 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 concept though 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 gauge the output of a fireplace is in case you detect you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. 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 developed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are usually equipped with a massive 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 fire is burning. During this time period the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the next stage. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace media console
