Ancient fire pits were sometimes built from the floor, in caves, or in the center of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced toxic and/or irritating smoke inside the house.Fire pits developed into raised hearths in buildings, but venting smoke relied on open windows or openings in roofs. The great hall typically had a centrally located hearth, where a open fire burnt with the smoke climbing into the vent 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.
Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it outside via a wall or roof. These can be placed against rock walls, instead of taking up the middle of the room, and this enabled smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings handily. They didn't come into general usage instantly, however, as they were expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting out a longer place on top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing the smoke up 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 kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Instead it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a sign of wealth, which to some degree is still the idea today.A fireplace is a construction made from brick, stone or metal made to include a fire. Fireplaces are used for the relaxing ambiance they create and for heating a room. Modern fireplaces vary in heat efficiency, depending on the plan.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses.

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 exterior walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic 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 good, but it's not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A few 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 gel, liquid propane, bottled gas or natural gas. In the USA, several states and local counties have laws restricting these types of fireplaces. They must be suitably sized to the area to be heated. There are also air quality control issues because of 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 place that is heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a room, allowing more individuals 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 designers of the period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, instead of their size.
From 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, usually in wood, granite or marble. The fit was where the fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were thought to add a cozy ambiance to houses.Placing a TV Over Your Fireplace A Do or a Dont?

Some fireplace units include a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency can also be enhanced by means of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. The ideal way to estimate the output signal of a fireplace is if you detect you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. 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 modified 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 often equipped with a large fire window, enabling an efficient heating process in two stages. During the first phase the first heat is provided through a big glass window while the flame is burning. In 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 just provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.tv above fireplace
