Historical fire pits were sometimes constructed from the floor, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or irritating smoke inside the house.Fire pits grown into raised hearths in buildings, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burnt with all the smoke rising to 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.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out through a ceiling or wall. These can be placed against rock walls, instead of taking up the middle of the room, and this enabled smaller rooms to be warmed.Chimneys were invented 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 made it feasible to place fireplaces in numerous rooms in buildings conveniently. They did not come into general use instantly, however, since they were expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer place at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing up the smoke and from the construction. The shallow design also improved greatly the quantity of radiant warmth projected to the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and also deflected unnecessary ornamentation. Instead it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality stone. Stone fireplaces now have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficacy, based upon the plan.Historically they have been 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 other flue allows exhaust to escape. A fireplace might have the following: a base, 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 chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the casting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesManufactured fireplaces are made out of 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.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, several states and local counties have laws restricting these types of fireplaces. Additionally, there are air quality control issues because of the quantity of moisture that they release into the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the area that's heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were usually centered within a space, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace designers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly lit, with a emphasis on the level of the substances used in their construction, instead of their size.
From the 1800s newest fireplaces were made up of 2 components, the surround and the insert. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was fire burned, and was constructed of cast iron often backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance to houses.Contemporary Fireplaces I Designer Fireplaces I Luxury Fireplaces Video
Some fireplace units include a blower that 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 enhanced with the use of a fireback, a sheet of metal which sits behind the flame 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 complex notion though with open hearth fireplaces. Most efficiency tests consider only the effect of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The ideal way to gauge the output of a fireplace is in case you notice you're turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two phases. During the first phase the first heat is offered through a large glass window while the fire is burning. During this time period the construction, constructed of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Depending on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace design
