Historical fire pits were sometimes constructed in the ground, within caves, or at the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or annoying smoke inside the house.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where a open fire burnt with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out via a ceiling or wall. These can be put against rock walls, instead of taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general use immediately, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer area at the top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's design is the foundation for modern kitchens.
Rather it depended on simple layouts with little unnecessary ornamentation. In 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 a degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, where 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 from the outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.

Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, some states and local counties have laws restricting these types of fireplaces. Additionally, there are air quality control issues due to the amount of moisture they discharge in the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that is heated, and port all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits than modern fireplaces.

Many defects were found in ancient fireplace designs. The most famous fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s newest fireplaces were composed of 2 components, the surround and the add. The surround consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The insert was fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance to houses.Osburn 2200 Metallic Black EPA Wood Burning Fireplace Insert OB02201 Northline Express Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the atmosphere. The best method to gauge the output of a fireplace is if you detect you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two phases. During the first stage the initial heat is provided through a large glass window while the flame is burning. In this time the structure, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the second phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.wood burning fireplace insert
