Ancient fire pits were sometimes built from the ground, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or irritating smoke inside the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open flame burnt with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it outside through a wall or roof. These can be placed against rock walls, instead of taking up the middle of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They did not come into general use instantly, however, as they were expensive to develop and maintain.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 efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a lengthier area on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant warmth projected into the room. Rumford's design is the foundation for modern fireplaces.
Instead it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time were a sign of prosperity, which to some degree is still the idea today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a room. Modern fireplaces change in heat efficiency, based upon 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 alternative flue allows exhaust to escape. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a throat, 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 act 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 problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.

In the USA, several states and local businesses have laws limiting these kinds of fireplaces. Additionally, there are air quality control issues because of the amount of moisture that they release into the room atmosphere, and oxygen detector and carbon monoxide 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 vent all exhaust gasses to the outside of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were more 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 house. These fire pits were generally centered within a room, allowing more individuals to gather around it.

Many flaws were found in early fireplace designs. The most famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly colored, with a emphasis on the level of the substances used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were composed of 2 parts, the surround as well as the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The insert was fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to houses.Gas Log Fireplace Repair Services Gas Log Fireplace Pros Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced with the use of a fireback, a sheet 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 complex concept though with open hearth fireplaces. Most efficacy tests consider only the impact 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 toaster, and has done so since the 15th century. The ideal method 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 comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting 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 large glass while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the second phase. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.gas fireplace repair
