Ancient fire pits were sometimes built from the floor, in caves, or in the middle of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they generated hazardous or irritating smoke inside the dwelling.Fire pits developed into elevated hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with the smoke climbing into the port in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so snow and rain would not enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it outside through a wall or roof. These can be placed against stone walls, instead of taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general use instantly, however, since they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier area at the top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which has been better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant heat projected to the room. Rumford's design is the basis for modern fireplaces.
Instead it depended on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces at this time were 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 include a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces change in heat efficiency, based on the design.Historically they were utilized 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.

On the exterior there is frequently a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
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 limiting these types of fireplaces. There are also air quality control issues due to the quantity of moisture that they discharge in the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place that's heated, and port all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were usually based within a room, allowing more people to collect around it.

Many defects were found in early fireplace designs. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It had been smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were composed of two parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was where the fire burned, 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 into homes.Planika Fires Offical company blog: TV mounted over a bio ethanol fireplace Video
Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also enhanced with the use of a fireback, a piece of metal that sits behind the flame 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 impact of heating of the atmosphere. 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 since the 15th century. The best method to gauge the output signal of a fireplace is if you notice you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two stages. During the first phase the first heat is provided through a big glass window while the fire is burning. In this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.ethanol fireplace
