Ancient fire pits were sometimes built in the ground, within 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 early indoor fire pits was that they generated toxic and/or irritating smoke within the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it outside via a ceiling or wall. These can be placed against rock walls, instead of taking up the center of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue 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 multiple rooms in buildings handily. They did not come into general usage immediately, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a lengthier area on very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and from the building. The shallow design also improved greatly the quantity of radiant warmth projected into the room. Rumford's layout is the foundation for modern kitchens.
Instead it relied 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 have been a symbol of prosperity, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficiency, depending upon the design.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home 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 act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a far larger problem 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 integrated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not good for you.Types of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electrical 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 gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws limiting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control problems due to the quantity of moisture they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either 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.

Over time, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits compared to modern 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 based within a space, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were composed of two parts, the surround and the add. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was where the fire burned, and was built of cast iron often backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance into houses.25+ best ideas about Outdoor stone fireplaces on Pinterest Outdoor fireplace designs, Outdoor Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also increased with the use 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 made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace isn't, 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 ideal way to gauge the output of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two phases. During the first stage the first heat is offered through a large glass while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.outdoor fireplaces
