Ancient fire pits were sometimes constructed in the ground, in caves, or in the center of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of premature indoor fire pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open flame burnt with all the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.

Also throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through a room and vent it outside via a wall or roof. These could be placed against stone walls, instead of taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings handily. They didn't come into general use immediately, however, since they were expensive to develop and maintain.

The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a lengthier area at the 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 construction. The shallow design improved greatly the amount of radiant heat projected into the room. Rumford's design is the basis for modern fireplaces.

Instead it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces at this time have been a symbol of prosperity, which to a degree is still the notion today.A fireplace is a structure made from brick, stone or metal made to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, based on the design.

Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, where the projecting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor integrated 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 can pose a significant health risk. The EPA writes"Smoke may smell great, but it is not great for you.

Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric 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 counties have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management issues because of the quantity of moisture they release into the room atmosphere, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are completely sealed from the place that is heated, and vent all exhaust gasses into the outside of the structure.

AccessoriesFor the inside, common in recent Western cultures include grates, fireguards, log boxes, andirons, bark baskets, and fire dogs, all which cradle gas and quicken burning. A grate (or fire grate) is a frame, usually of iron bars, to maintain fuel for a fire. Heavy metallic firebacks are occasionally utilized to capture and re-radiate warmth, to safeguard the rear of the fireplace, and as decoration. Fenders are low metallic frames set before the fireplace to include embers, soot and ash. Other wider accessories can consist of log baskets, companion sets, coal buckets, cabinet accessories and more.

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

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, instead of their dimensions.

From the 1800s newest fireplaces were made up of two parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to bring a cozy ambiance into homes.

Some fireplace components include a blower that transports 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 can also be increased 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 can also be made from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to warm the air. The best method to gauge the output of a fireplace is if you notice you are turning the thermostat up or down.

Most elderly fireplaces have a relatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating process in two phases. During the first stage the first heat is provided through a big glass window while the flame is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces with no glass fire window just provide heat radiated from its surface. Depending on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.ethanol fireplace
