Ancient fire pits were sometimes built from the floor, within caves, or at the middle of a hut or home. Evidence of prehistoric, man-made fires exists on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or irritating smoke within the house.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where an open fire burnt with all the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be coated so rain and snow wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing an area and vent it outside via a ceiling or wall. These could be put against rock walls, rather than taking up the center of the room, and this enabled smaller rooms to be heated.Chimneys were devised 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 made it feasible to put fireplaces in numerous rooms in buildings handily. They did not come into general use instantly, however, since they were expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that 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 longer area on very 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 also improved greatly the amount of radiant warmth projected to the space. Rumford's design is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and also deflected unnecessary ornamentation. Rather it depended on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces at this time have been a symbol of prosperity, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal designed to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficacy, depending on the plan.Historically they have been used for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is often a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud serves to keep rainwater out of the outside of the chimney; rain in the chimney is a much larger difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the standard masonry chimney, which divides up all but the most violent rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for 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.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws restricting these kinds of fireplaces. There are also air quality control problems due to the quantity of moisture they discharge in the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in 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 visual interest. Early ones were fire pits than modern fireplaces. They have been used for warmth on cold days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were usually centered within a room, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. Together with the Industrial Revolution, came big scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of this time 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 quality of the materials used in their construction, as opposed to their dimensions.
By the 1800s newest fireplaces were made up of two components, the surround as well as the add. The surround comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance into houses.Fireplace Accessories Fireplace Shop Erie PA Video
Some fireplace units incorporate a blower that transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but can also be made 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 is not, and never was, designed to heat the atmosphere. The best way to gauge the output signal of a fireplace is in case you notice you're turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency score. 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 may also be modified by inserting special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80% in heating the air. These altered fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two stages. During the first stage the initial heat is provided through a big glass while the fire is burning. During this time the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace accessories
