Ancient fire pits were sometimes constructed from the ground, in caves, or at the middle of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated hazardous or irritating smoke within the house.Fire pits grown into raised hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burnt with the smoke rising to the vent 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 during the Middle Ages, smoke canopies were devised 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 middle of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe from 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 made it possible to put fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, as they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting out a lengthier area at the very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the amount of radiant heat projected to the room. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it depended on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time were a sign of prosperity, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficiency, based upon the plan.Historically they have been used for heating a home, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape. A fireplace might have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's frequently a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain in the chimney is a far larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that divides up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made with 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.
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. There are also air quality control problems due to the amount of moisture that they discharge into the room atmosphere, 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 totally sealed from the area that is heated, and port all exhaust gasses to the outside of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than modern fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were generally centered within a room, allowing more people to gather around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s most new fireplaces were made up of two parts, the surround as well as the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance to homes.Dimplex Essex Electric Fireplace Reviews Wayfair Video
Some fireplace units incorporate a blower which transfers 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 piece of metal which 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 efficacy tests consider just the impact of heating of the air. An open fireplace is not, and never was, intended to heat the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal method to estimate the output signal of a fireplace is if you notice you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two phases. During the first phase the first heat is provided through a large glass window while the flame is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Depending on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.electric fireplaces
