Historical fire pits were sometimes constructed in the ground, within caves, or in the middle of a hut or home. Evidence of prehistoric, man-made flames is present on all five inhabited continents. The drawback of premature indoor fire pits was that they generated toxic and/or annoying smoke inside the dwelling.Fire pits grown into raised hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burnt with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing an area and vent it outside through a ceiling or wall. These can be placed against stone walls, instead of taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and also made it possible to place fireplaces in multiple rooms in buildings handily. They didn't come into general usage instantly, 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 that greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a longer place on very top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and from the building. The shallow design improved greatly the quantity of radiant heat projected into the room. Rumford's design is the foundation for modern kitchens.
Rather it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality gems. Stone fireplaces at this time were a symbol of prosperity, which to some degree remains the notion today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficacy, depending on the plan.Historically they were utilized for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the projecting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the outside of the chimney; rain at 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 most violent rain. Some 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.Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical 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 United States, several states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality management problems due to the amount of moisture they discharge in the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the place that is heated, and port all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were generally centered within a space, allowing more people to collect around it.

Many defects were found in early fireplace designs. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their size.
From the 1800s most new fireplaces were composed of two parts, the surround and the add. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into houses.How to Whitewash a Brick Fireplace Erin Spain Video
Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be enhanced with the use of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to heat the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal method to estimate the output of a fireplace is if you detect you're 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 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the initial heat is offered through a big glass window while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next stage. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Depending on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.whitewash fireplace
