Ancient fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or annoying smoke within the dwelling.Fire pits grown into elevated hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where a open flame burnt with all 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 snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it outside via a ceiling or wall. These could be placed against stone walls, rather than taking up the center of the room, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings handily. They did not come into general usage instantly, however, as they were more 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 that greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a longer place at the top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant heat projected into the room. Rumford's layout is the basis for modern fireplaces.
Rather it depended on simple designs 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 stone. Stone fireplaces at this time have been a sign of wealth, which to a degree remains the notion today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a room. Modern fireplaces change in heat efficacy, depending on the design.Historically they were used for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the United States, some states and local counties have laws limiting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control problems because of the quantity of moisture that they release in the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally 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 changed from one of necessity to one of visual interest. Early ones were fire pits than modern fireplaces. They have been used for warmth 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 centered within a space, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, instead of their size.
From the 1800s most new fireplaces were composed of two components, 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. In addition to providing heat, the fireplaces of the Victorian age were thought to add a cozy ambiance into houses.Decorating Ideas for Fireplace Mantels and Walls DIY 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 decrease heating load. Fireplace efficiency is also enhanced with the use of a fireback, a sheet of metal which sits behind the fire 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 impact of heating of the atmosphere. 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 ideal way to gauge the output of a fireplace is if you detect you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two stages. During the first stage the first heat is provided through a big glass while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Depending on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace ideas
