Ancient fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated toxic and/or annoying smoke within 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 an open fire burned with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside via a wall or roof. These could be put against stone walls, instead of taking up the center of the room, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings handily. They did not come into general usage instantly, however, as they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. The 18th century saw two major developments in the history of fireplaces. 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 out a longer place on very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the amount of radiant warmth projected into the space. Rumford's layout is the basis for modern fireplaces.
Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a sign of prosperity, which to some degree is still the notion today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are used for its relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficacy, depending on the design.Historically they have been used for heating a home, 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 is frequently 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 cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not great for you.Types of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A few 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 gas fuel sources. In the USA, some states and local businesses have laws restricting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management problems due to the quantity of moisture that they discharge in the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the place that is heated, and vent 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 modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were usually based within a room, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. The most renowned fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were composed of 2 parts, the surround and the insert. The encircle consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was where the fire burned, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.Fireplace Mantels Orland Prestige Wood Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a decrease 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 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 atmosphere. An open fireplace is not, and never was, intended to heat the atmosphere. The best method to estimate the output signal of a fireplace is in case you notice you are turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are often equipped with a large fire window, enabling an efficient heating system in two stages. During the first phase the initial heat is provided through a large glass while the flame is burning. In this time the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.wood fireplace mantels
