Ancient fire pits were sometimes built from the floor, in caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor fire pits was that they generated toxic and/or annoying smoke within the dwelling.Fire pits developed into raised hearths in structures, but ventilation smoke relied on open windows or holes in roofs. The great hall typically needed a centrally located hearth, where an open flame burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain would not enter.
Also during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside through a wall or roof. These can be put against stone walls, instead of taking up the middle of the space, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to place fireplaces in multiple rooms in buildings handily. They did not come into general use immediately, however, as they were 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 room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a longer place on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing the smoke up and from the construction. The shallow design improved greatly the amount of radiant warmth projected to the room. Rumford's layout is the basis for modern fireplaces.
Rather it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces at this time have been a symbol of prosperity, which to some degree is still the idea today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficacy, based upon the design.Historically they have been used for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, in which the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a much larger problem in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor integrated 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 can pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not great for you.Types of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws restricting these kinds of fireplaces. They must be suitably sized to the area to be heated. There are also air quality control issues because of the amount of moisture they discharge 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 completely sealed in the area that is heated, and port all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were more fire pits compared to contemporary fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also functioned as a gathering place within the home. These fire pits were usually based within a space, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design that has been used for generations. It was smaller, more brightly colored, with an emphasis on the quality of the materials used in their construction, instead of their size.
From the 1800s newest fireplaces were made up of two parts, the surround as well as the add. The encircle consisted of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was fire burned, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were thought to bring a cozy ambiance into houses.Legends Furniture Berkshire TV Stand with Electric Fireplace Walmart.com Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased 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 made from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace is not, and never was, intended to warm the atmosphere. The best method to estimate the output signal of a fireplace is if you notice you're turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two stages. During the first phase the first heat is offered through a big glass window while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.walmart electric fireplace tv stand
