Ancient fire pits were sometimes constructed from the ground, within caves, or in the center of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage 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 ventilation smoke relied on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where a open fire burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it out via a ceiling or wall. These can be placed against rock walls, rather than taking up the middle of the space, and this enabled smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage instantly, however, as they were expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting a longer place on top. At 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 kitchens.
Instead it depended on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality gems. Stone fireplaces now were a sign of wealth, which to some degree is still the idea today.A fireplace is a construction made from brick, stone or metal designed to include a fire. Fireplaces are used for the relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficiency, depending upon the design.Historically they were utilized for heating a dwelling, 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. A fireplace may 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, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick act as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, that divides up all but the most violent 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.Kinds of fireplacesManufactured fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several 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 management problems due to the amount of moisture they discharge in the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that's heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were fire pits than modern fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally centered 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, necessitating a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly lit, with an emphasis on the level of the materials used in their construction, instead of their dimensions.
By the 1800s most new fireplaces were made up of 2 components, the surround as well as the add. The encircle consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was where the fire burnt, and was built of cast iron often backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to houses.Open Fireplace Designs to Warm Your Home Video
Some fireplace components include a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency is also enhanced with the use of a fireback, a sheet 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 notion though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal method to estimate the output of a fireplace is if you notice you are turning the thermostat down or up.
Most elderly 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 such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are often equipped with a massive fire window, enabling an efficient heating system in two phases. During the first phase the first heat is provided through a large glass while the flame is burning. In this time the construction, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.double sided fireplace
