Ancient fire pits were sometimes constructed from 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 flame pits was that they produced hazardous or annoying smoke inside the house.Fire pits developed into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open fire burned with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it outside through a ceiling or wall. These can be placed against rock walls, instead of taking up the center of the room, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and also made it possible 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.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier area at the top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the building. The shallow design also improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Instead it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality stone. Stone fireplaces at this time have been a symbol of prosperity, which to some degree remains the notion today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, depending on the plan.Historically they were utilized for heating a home, 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 crane (used in laundry and kitchen 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 frequently a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for wood or gas 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 United States, several states and local businesses have laws restricting these kinds of fireplaces. They must be suitably sized to the area to be heated. There are also air quality management issues because of the amount of moisture that they discharge into the room air, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the area that is heated, and vent all exhaust gasses to the exterior of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of interest. Early ones were fire pits than modern fireplaces. They were used for warmth on chilly days and nights, as well as for cooking. They also served as a gathering place inside the house. These fire pits were usually based within a room, allowing more people to gather around it.

Many flaws were found in early 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 a emphasis on the quality of the substances used in their construction, instead of their size.
By the 1800s newest fireplaces were composed of two parts, the surround and the add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burnt, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.Turning On Gas Fireplace How To Light A Gas Fireplace Pilot Light Turning On Gas Fireplace Video
Some fireplace components incorporate a blower that transports 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 piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the atmosphere. A fireplace with a fireback is a toaster, and has done so since the 15th century. The best way to gauge the output signal of a fireplace is in case you notice you're turning the thermostat up or down.
Most older 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 improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating process in two phases. During the first stage the initial heat is offered through a big glass window while the flame is burning. In this time period the structure, 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 just provide heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.how to turn on gas fireplace
