Historical fire pits were sometimes constructed from the floor, in caves, or in the center of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of early indoor fire pits was that they produced toxic and/or annoying smoke inside the dwelling.Fire pits developed into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where a open fire burned with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside via a wall or roof. These could be put against rock walls, rather than taking up the center of the room, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage immediately, however, since they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer area on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the building. The shallow design improved greatly the quantity of radiant warmth projected to the room. Rumford's design is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and deflected unnecessary ornamentation. Instead it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality gems. Stone fireplaces now were a symbol of prosperity, which to some degree remains the idea today.A fireplace is a construction made of brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, based 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 foundation, 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 chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the casting courses of brick act as a drip route 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 in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, that divides up all but the most violent rain. Some 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 different studies, fireplaces can pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not great for you.Kinds of fireplacesManufactured fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either 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 gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these kinds of fireplaces. There are also air quality control issues because of the quantity of moisture they discharge into the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are 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 purpose of fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were generally centered within a space, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly colored, with a emphasis on the level of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of 2 parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to bring a cozy ambiance into homes.2Q FIREPLACE GRATE HEATER FURNACE BLOWER TUBE HEAT EXCHANGER HEATILATOR WOOD eBay Video
Some fireplace units include a blower which transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated concept 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, intended to warm the atmosphere. The best way to estimate the output of a fireplace is if you detect you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are usually equipped with a large fire window, enabling an efficient heating process in two phases. During the first phase the first heat is provided through a large glass while the fire is burning. In this time the structure, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the second phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.fireplace heat exchanger
