Ancient fire pits were sometimes constructed in the ground, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or annoying smoke inside the house.Fire pits developed into raised hearths in structures, but venting smoke depended on open windows or holes in roofs. The great hall typically needed a centrally located hearth, where an open flame burned with all the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside through a ceiling or wall. These can be put against stone walls, rather than taking up the center of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings handily. They did not come into general use immediately, however, as they were expensive to build 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 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 made a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant warmth projected into the space. Rumford's design is the basis for modern kitchens.
Rather it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces now were a sign of wealth, which to some degree remains the idea today.A fireplace is a construction 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 plan.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick function as a drip course 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 much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for 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 gas fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality management issues because of the amount of moisture that they release into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed from the area that's heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were fire pits than modern fireplaces. They were used for warmth 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 individuals to gather around it.

Many defects were found in early fireplace designs. The most famous fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were made up of 2 parts, the surround and the insert. The surround consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burned, and was built of cast iron frequently backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to add a cozy ambiance into houses.DIY Stone Fireplace Reveal for real! Evolution of Style Video
Some fireplace components 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 by means 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 complicated concept although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, and never was, intended to heat the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The best method to estimate the output of a fireplace is if you notice you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first phase the initial heat is offered through a big glass while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the next stage. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace
