Historical fire pits were sometimes constructed in the floor, in caves, or at the middle of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated hazardous or annoying smoke within the house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burnt with all the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Also during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside through a wall or roof. These could be placed against stone walls, instead of taking up the middle of the room, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, since they were expensive to develop 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 improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier place at the top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing the smoke up and from the building. The shallow design also improved greatly the quantity of radiant heat projected to the room. Rumford's design is the basis for modern kitchens.
Instead it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces now were a symbol of wealth, which to some degree remains the idea today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending upon the plan.Historically they were utilized for heating a dwelling, 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 crane (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a neck, 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 act as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that divides up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesManufactured 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 electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. 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 counties have laws limiting these types of fireplaces. They must be properly sized to the area to be heated. There are also air quality control problems because of the amount of moisture they discharge in the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the area that's heated, and port all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They were used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the house. These fire pits were generally based within a space, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s newest fireplaces were composed of 2 components, the surround as well as the add. The encircle consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burned, and was constructed 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 into houses.Media Console Fireplaces TV Stands Walmart.com Video
Some fireplace components incorporate a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace isn't, and never was, intended to heat the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best method to estimate the output signal of a fireplace is if you notice you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80% in heating the air. These altered fireplaces are usually 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 large glass window while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.walmart electric fireplace tv stand
