Ancient fire pits were sometimes built in the floor, in caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they produced hazardous or irritating smoke within the house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where an open flame burnt with the smoke rising to the port in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were invented to prevent smoke from dispersing a room and vent it out through a ceiling or wall. These could be put against stone walls, rather than taking up the middle of the space, and this allowed smaller chambers to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general use immediately, however, since they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a cellar and venting out a lengthier area at the very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and out of the building. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's design is the basis for modern kitchens.
Rather it relied on simple layouts with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces now have been a sign of prosperity, which to a degree is still the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficiency, based upon the plan.Historically they have been used for heating a dwelling, 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 frequently 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 hood, cap, or shroud functions to keep rainwater from the outside of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that divides up all but the most violent rain. Some chimneys have a spark arrestor incorporated 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 can pose a substantial health threat. The EPA writes"Smoke may smell great, but it is not good for you.Types of fireplacesArtificial fireplaces are made with 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, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. There are also air quality control problems because of the quantity of moisture they discharge in the room atmosphere, and oxygen sensor 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 is heated, and port all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were fire pits than modern fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were usually based within a room, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, requiring 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 an emphasis on the level of the materials used in their construction, instead of their dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround and the add. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into homes.Pleasant Hearth Dual Fuel Vent Free Gas Fireplace Reviews Wayfair Video
Some fireplace components include a blower which transports 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 is also enhanced with the use of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficacy tests consider just the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the atmosphere. The ideal method to gauge the output signal of a fireplace is if you detect 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 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 may reach efficiencies as high as 80% in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating process in two stages. During the first phase the first heat is provided through a large glass window while the flame is burning. During this time the structure, constructed of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next phase. Masonry fireplaces without a glass fire window just provide heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.vent free gas fireplace
