Historical fire pits were sometimes built in the floor, within caves, or at the middle of a hut or home. Evidence of ancient, 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 venting smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open flame burned with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it out through a ceiling or wall. These could be put against rock walls, instead of taking up the center of the space, and this enabled smaller chambers 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 possible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They did not come into general usage instantly, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber 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 at the very top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing up the smoke and out of the building. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's design is the basis for modern fireplaces.
Rather it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces now have been a sign of wealth, which to a degree remains the notion today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, based on the plan.Historically they were utilized for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves 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 metal liners compared with the traditional masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health risk. The EPA writes"Smoke may smell good, but it's not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either gas or wood 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 gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, some states and local businesses have laws restricting these types of fireplaces. They must 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 sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed from the area that's heated, and port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits compared to contemporary fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally based within a space, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace designers of the time 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, instead of their dimensions.
From the 1800s newest fireplaces were made up of two parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance to houses.Regency Gas Fireplace Panorama P33,P33E AND P33CE Gas Fireplace The Fireplace Club Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal method to estimate the output of a fireplace is in case you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the first heat is offered through a big glass while the fire is burning. In this time period the construction, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Depending on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.regency fireplace
