Ancient fire pits were sometimes constructed in the ground, in caves, or at the middle of a hut or dwelling. Evidence of prehistoric, man-made flames exists 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 developed into elevated hearths in structures, but venting smoke relied on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where a open flame burned with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it out via a ceiling or wall. These could be put against stone walls, instead of taking up the middle of the room, and this enabled smaller rooms to be heated.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and also made it feasible to put fireplaces in numerous rooms in buildings handily. They didn't come into general usage immediately, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a longer place at the top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and out of the building. The shallow design also improved greatly the amount of radiant warmth projected into the room. Rumford's layout is the basis for modern kitchens.
Instead it depended on simple layouts with little 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 stone. Stone fireplaces at this time have been a symbol of wealth, which to a degree is still the notion today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficacy, depending on the plan.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there's often a corbeled brick crown, where the casting courses of brick function as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the exterior of the chimney; rain at the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for either wood or gas 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.
In the United States, several states and local businesses have laws restricting these kinds of fireplaces. There are also air quality management issues due to the quantity of moisture they release into the room air, and oxygen detector and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the area that's heated, and vent all exhaust gasses into the exterior of the structure.

It was smaller, more brightly colored, with an emphasis on the level of the substances used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were made up of 2 components, the surround as well as the insert. The surround consisted of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was where the fire burnt, and was constructed of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance into houses.Fire Sense 60757 1350 Watt Wall Mounted Electric Fireplace eBay Video
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 space and a lower heating load. Fireplace efficiency is also enhanced by means of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace is not, and never was, intended to heat the air. The best method to estimate the output of a fireplace is in case you notice you are turning the thermostat down or up.
Most older fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 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 cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the initial heat is provided through a big glass while the flame is burning. During this time the structure, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for many hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.wall mounted electric fireplace
