Ancient fire pits were sometimes built in the ground, in caves, or at the center of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits grown into raised hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where an open flame burned with the smoke climbing into the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Additionally throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out through a ceiling or wall. These can be placed against stone walls, instead of taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke out. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings handily. They didn't come into general use instantly, 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 airflow and venting system. Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier area at the top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that was better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant heat projected to the room. Rumford's layout is the basis for modern fireplaces.
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 placed on providing quality stone. Stone fireplaces at this time were a sign of prosperity, which to some degree is still the idea today.A fireplace is a structure made of brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they have been 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 alternative flue allows exhaust to escape.

On the exterior there is 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 hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A couple of kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the USA, some states and local counties have laws limiting these kinds of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality control problems because of the quantity of moisture that they release in the room air, and oxygen sensor and carbon monoxide 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 port all exhaust gasses into the exterior of the structure.

Over time, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were fire pits compared to contemporary fireplaces. They were used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally centered within a space, allowing more individuals to collect around it.

Many flaws were found in early fireplace designs. Together with the Industrial Revolution, came big scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their dimensions.
By the 1800s newest fireplaces were made up of two components, the surround and the insert. The surround comprised of the mantlepiece and sides supports, 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 era were thought to add a cozy ambiance to homes.The Special Z for Majestic Fireplaces Video
Some fireplace components include a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be enhanced by means of a fireback, a sheet of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, intended to warm the air. The best 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 rating. Standard, modern, wood-burning masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a large fire window, allowing an efficient heating process in two phases. During the first phase the initial heat is offered through a big glass window while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the second stage. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Depending on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.majestic fireplace
