Historical fire pits were sometimes built in the floor, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature 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 relied on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burned with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it out via a wall or roof. These could be placed against rock walls, rather than taking up the center of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible 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, since 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 room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a longer place at the very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the building. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the basis for modern kitchens.
Rather it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces at this time have been a symbol of wealth, which to some degree is still the idea today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficacy, based upon the design.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, in which the projecting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesArtificial fireplaces are made with sheet metal or glass fire 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 electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the United States, several states and local counties have laws restricting these types of fireplaces. They must be properly sized to the area to be heated. There are also air quality management problems because of the quantity of moisture that they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the place that is heated, and port all exhaust gasses to the outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits than modern fireplaces. They have been used for warmth on chilly 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 collect around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were composed of 2 parts, the surround and the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.Pearl Mantels Richmond Fireplace Mantel Surround Reviews Wayfair Video
Some fireplace components include a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a piece of metal which 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 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 gauge the output of a fireplace is if you detect you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two stages. During the first phase the initial heat is offered through a big glass while the fire is burning. During this time period the construction, constructed of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace mantels
