Historical fire pits were sometimes constructed from the floor, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor flame pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits grown into raised hearths in structures, but venting smoke depended on open windows or holes in roofs. The great hall typically needed a centrally situated hearth, where a open fire burned with all the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside through a wall or roof. These could be placed against rock walls, rather than taking up the center of the space, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use instantly, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a lengthier area at the very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing up the smoke and out of the construction. The shallow design also improved greatly the amount of radiant warmth projected to the space. Rumford's design is the foundation for modern fireplaces.
Instead it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces at this time were a sign of wealth, which to some degree is still the notion today.A fireplace is a structure made of brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficiency, depending on the plan.Historically they have been utilized for heating a home, 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 (utilized in kitchen and laundry 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 casting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater out of the outside of the chimney; rain at the chimney is a far larger problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which divides up all but the 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 various studies, fireplaces could pose a significant health threat. The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.A couple of types 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 gel, liquid propane, bottled gas or natural gas. In the USA, some states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality control issues due to the amount of moisture that they release in the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the area that's heated, and vent all exhaust gasses to the outside of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were more fire pits compared to modern fireplaces. They have been used for heat on cold days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a room, allowing more people to collect around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the materials used in their construction, as opposed to their dimensions.
By the 1800s most new fireplaces were composed of two parts, the surround as well as the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burned, and was built of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.Fire Sense Stainless Steel WallMounted Electric Fireplace with Heater Video
Some fireplace units include a blower that transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency is also enhanced by means of a fireback, a piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to heat the atmosphere. The best method to estimate the output of a fireplace is in case you notice you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80% in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two stages. During the first stage the first heat is offered through a big glass while the fire is burning. During this time the structure, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just offer heat radiated from the surface. Depending on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.wall fireplace heater
