Historical fire pits were sometimes built in the ground, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or irritating smoke inside the dwelling.Fire pits developed into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The 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 throughout the Middle Ages to enable the roof vents to be coated so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it out through a wall or roof. These can be put against rock walls, rather than taking up the center of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general use immediately, 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 venting and airflow system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting 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 building. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's design is the basis for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on stone and deflected unnecessary ornamentation. Rather it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality gems. Stone fireplaces now were a sign of wealth, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficacy, depending upon the design.Historically they have been used for heating a dwelling, cooking, and heating water for laundry and domestic uses.

On the exterior there's frequently a corbeled brick crown, where the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor integrated into the cap or crown.
Organizations like 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 great for you.Types of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
In the USA, several states and local counties have laws restricting these types of fireplaces. There are also air quality control problems due to the quantity of moisture that they discharge in the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and vent all exhaust gasses to the outside of the structure.

Over time, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits than contemporary fireplaces. They were used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home.

Some fireplace components include a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also increased by means 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 are also made from stainless steel. Efficiency is a complex concept although 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 air. The ideal way to gauge the output of a fireplace is in case you detect you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the atmosphere. These altered 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 large glass window while the fire is burning. In this time period the structure, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.lowes electric fireplace
