Ancient fire pits were sometimes built in the floor, within caves, or in the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor fire pits was that they generated toxic and/or irritating smoke within the house.Fire pits grown into elevated hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where an open fire burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it outside through a ceiling or wall. These could be placed against rock walls, rather than taking up the middle 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 issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general use immediately, however, since they were more expensive to develop and maintain.The 18th century saw two important 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. He also improved the airflow by pulling air from a basement and venting out a lengthier place on top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the foundation for modern fireplaces.
Rather it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces at this time have been a symbol of prosperity, which to a degree is still the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficiency, based on the design.Historically they have been used for heating a dwelling, 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 foundation, a hearth, a firebox, a mantelpiece; a chimney (used in laundry and kitchen 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, where the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain at the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell good, but it's not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either wood or gas 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 gas fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, some states and local businesses have laws limiting these types of fireplaces. Additionally, there are air quality management issues because of the amount of moisture that they discharge in the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the area that is 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 compared to contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place inside the home. These fire pits were generally based within a room, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s most new fireplaces were made up of two components, the surround as well as the insert. The surround comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was fire burnt, and was built of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance to homes.Classic Flame Windsor TV Stand with Electric Fireplace Reviews Wayfair Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced by means 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 complex notion although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, and never was, designed to heat the atmosphere. The best way to estimate the output of a fireplace is if you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 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 large as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two phases. During the first phase the initial heat is offered through a large glass while the flame is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.tv stand with electric fireplace
