Ancient fire pits were sometimes built from the ground, in caves, or in the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated hazardous or irritating smoke inside the house.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where an open fire burned with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it out via a wall or roof. These could be placed against stone walls, rather than taking up the middle of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general usage immediately, however, since they were expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer place on very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and out of the construction. The shallow design improved greatly the quantity of radiant heat projected to the room. Rumford's layout is the foundation for modern kitchens.
Rather 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 placed on supplying quality stone. Stone fireplaces at this time were a symbol of wealth, which to a degree is still the notion today.A fireplace is a structure made of brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, based on the design.Historically they have been utilized for heating a home, 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 (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's frequently 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 serves to keep rainwater out of the outside of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which divides up all but the rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
Organizations like 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 fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas 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 businesses have laws limiting these kinds of fireplaces. Additionally, there are air quality management issues due to the amount 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 completely sealed in the area 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 necessity to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place within the house. These fire pits were generally based within a space, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of the time were the Adam Brothers. They perfected a style of fireplace design that has been 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 size.
By the 1800s newest fireplaces were made up of two components, the surround as well as the insert. The surround consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance to homes.How to Build a StoneVeneer Fireplace Surround This Old House Video
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 is also 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 produced from cast iron, but can also be made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the atmosphere. The ideal method to gauge the output of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes designed to burn cleaner and can reach efficiencies as large as 80% in heating the atmosphere. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two phases. During the first stage the first heat is offered through a big glass window while the flame is burning. In this time the structure, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the second phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace stone
