Ancient fire pits were sometimes constructed from the ground, within caves, or in the center of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke depended 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 climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it out via a ceiling or wall. These can be put against rock walls, instead of taking up the middle of the space, and this enabled smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke out. They made it possible to give the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage instantly, however, as they were expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a lengthier area on top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing up the smoke and from the construction. The shallow design improved greatly the quantity of radiant heat projected into the room. Rumford's design is the foundation for modern kitchens.
Rather it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces at this time have been a symbol of wealth, which to some degree is still the idea 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 for heating a space. Modern fireplaces vary in heat efficiency, depending on the design.Historically they have been utilized for heating a dwelling, 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 foundation, a hearth, a firebox, a mantelpiece; a chimney crane (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws limiting these types of fireplaces. Additionally, there are air quality management issues due to the amount of moisture that they release into the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been 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.

As time passes, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were usually based within a space, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. The most famous fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s most new fireplaces were composed of 2 components, the surround as well as the add. The surround consisted of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into houses.Duluth Stove Fireplace: Duluth, MN Superior, WI: Fireplaces, Gas and Wood Inserts, Stoves Video
Some fireplace components incorporate a blower that transfers 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 is also increased by means of a fireback, a sheet of metal which 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 is not, and never was, intended to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal method to estimate the output of a fireplace is in case you notice you're turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating system in two phases. During the first phase the first heat is provided through a big glass window while the fire is burning. In this time period the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace pictures
