Historical fire pits were sometimes constructed from the ground, within caves, or at the center of a hut or home. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated toxic and/or annoying smoke inside the house.Fire pits developed into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where an open fire burnt with the smoke rising to the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it outside via a ceiling or wall. These can be placed against stone walls, instead of taking up the center of the space, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to provide the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings handily. They did not come into general use immediately, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer place at the top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing up the smoke and out of the construction. The shallow design improved greatly the amount of radiant heat projected to the room. Rumford's design is the foundation for modern fireplaces.
Instead it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces now have been a symbol of prosperity, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficiency, based on the design.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape.

On the exterior there's frequently a corbeled brick crown, in which the projecting 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 from the outside of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations such as 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's not good for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
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, some states and local counties have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control issues due to the quantity of moisture they release into the room atmosphere, and oxygen sensor and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by either liquid propane or natural gas. They are totally sealed from the area that is heated, and port all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has changed from one of requirement to one of interest. Early ones were fire pits compared to contemporary fireplaces. They were used for heat on cold days and nights, in addition to for cooking. They also served as a gathering place within the home. These fire pits were usually centered within a space, allowing more individuals to collect around it.

Many defects were found in early fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly lit, with an emphasis on the quality of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of 2 parts, the surround and the insert. The encircle comprised of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was where the fire burned, and was constructed of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance to houses.Classic Flame® Lancaster Electric Fireplace 167653, Fireplaces at Sportsmans Guide Video
Some fireplace units incorporate a blower that transfers 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 enhanced with the use 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 made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the air. An open fireplace is not, and never was, intended to warm the atmosphere. The ideal way to gauge the output signal of a fireplace is in case you notice you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the air. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two phases. During the first stage the initial heat is provided through a big glass while the fire is burning. During this time the construction, built of refractory bricks, absorbs the heat. This warmth is then evenly radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace heaters
