Ancient fire pits were sometimes built from the ground, in caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits developed into elevated hearths in structures, but venting smoke relied on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where an open fire burned with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside via a ceiling or wall. These could be put against rock walls, instead of taking up the middle of the space, and this allowed smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, as they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased 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 chamber for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting a lengthier area on very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and from the construction. The shallow design improved greatly the quantity of radiant heat projected to the room. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and deflected unnecessary ornamentation. Instead it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces now were a sign of wealth, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal designed to contain 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 other flue allows exhaust to escape.

On the exterior there's frequently a corbeled brick crown, where the casting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is 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 wood or gas or retrofit with log inserts or electric fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, several states and local businesses have laws limiting these kinds of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality control problems due to the amount of moisture that they release in the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the place that's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of necessity 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, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a room, allowing more people to gather around it.

How to Build an Outdoor Stacked Stone Fireplace
Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of the 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 a emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of two parts, the surround and the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was fire burnt, and was constructed of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were thought to bring a cozy ambiance to houses.How to Build an Outdoor Stacked Stone Fireplace Video
Some fireplace units include a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to 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 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 notion though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best way to estimate the output of a fireplace is in case you notice you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as large 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 phases. During the first stage the initial heat is offered through a big glass while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.outdoor fireplace
