Ancient fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or annoying smoke inside the dwelling.Fire pits developed into elevated 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 burned with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it out through a ceiling or wall. These could be put against rock walls, rather than taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage immediately, however, since they were more expensive to develop and maintain.The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer area at the top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which has been better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's design is the foundation for modern fireplaces.
Rather it relied on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces now have been a sign of wealth, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal made to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficiency, based upon the plan.Historically they were utilized for heating a home, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a throat, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, in which the projecting courses of brick act as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which divides up all but the 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 different studies, fireplaces could pose a substantial health risk. The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesManufactured fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces can be built-in replacements for either wood or gas 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 USA, several states and local counties have laws limiting these kinds of fireplaces. Additionally, there are air quality management issues because of the quantity of moisture they release into the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed from the place that's heated, and vent all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits compared to modern fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were usually centered within a space, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s most new fireplaces were made up of 2 parts, the surround as well as the insert. The surround consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The insert was fire burnt, and was built of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to add a cozy ambiance to homes.Fireplaces Aqua Quip Seattle Tacoma Fireplace and Gas Insert Store Video
Some fireplace units incorporate a blower which transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency is also increased with the use of a fireback, a sheet of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complicated notion 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 heat the atmosphere. The best method to estimate the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two phases. During the first stage the first heat is provided through a big glass while the fire is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the second stage. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.regency fireplace
