Ancient fire pits were sometimes built in the floor, within caves, or at the middle of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated hazardous or annoying smoke within the house.Fire pits grown into raised hearths in structures, but venting smoke depended on open windows or holes in roofs. The great hall typically had a centrally located hearth, where a open fire burned with all the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from spreading through a room and vent it out via a wall or roof. These can be placed against stone walls, instead of taking up the center of the space, and this allowed smaller rooms to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the problem of fumes, more faithfully venting smoke out. They made it possible to give the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, as 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. In addition, he enhanced the airflow by pulling air from a cellar and venting a longer area at the very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing up the smoke and out of the building. The shallow design also improved greatly the amount of radiant heat projected into the space. Rumford's design is the foundation for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more traditional spectra based on rock and also deflected unnecessary ornamentation. Rather it depended on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces at this time 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 designed to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a space. Modern fireplaces vary in heat efficacy, 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. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, 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, where the projecting courses of brick function as a drip route 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 at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not great for you.Kinds of fireplacesArtificial fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. 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 counties have laws limiting these types of fireplaces. There are also air quality control issues because of the quantity of moisture that they discharge into the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the area that is heated, and vent all exhaust gasses into the outside of the structure.

As time passes, 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 heat on chilly days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were usually based within a room, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most famous fireplace designers of this time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
From the 1800s most new fireplaces were composed of 2 components, the surround and the insert. The surround comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The insert was fire burned, and was built of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance to homes.Home Decorators Collection Ravensdale 48 in.

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 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 produced from cast iron, but can also be manufactured from stainless steel. Efficiency is a complex notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to heat the atmosphere. The best way to gauge the output of a fireplace is if you notice you are turning the thermostat up or down.
Most older fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity for example in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by inserting special heavy fireboxes developed to burn cleaner and can reach efficiencies as high as 80 percent in heating the atmosphere. These altered fireplaces are often equipped with a large fire window, allowing an efficient heating system in two stages. During the first stage the first heat is offered through a big glass window while the flame is burning. During this time the structure, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.electric fireplace tv stand
