Ancient fire pits were sometimes built in the ground, in caves, or at the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or annoying smoke within the dwelling.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where an open flame burned with all the smoke climbing into the vent in the roof. Louvers were developed during 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 invented to prevent smoke from spreading through a room and vent it out via a ceiling or wall. These could be placed against rock walls, instead of taking up the center of the room, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke out. They made it possible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, as they were expensive to develop and maintain.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 efficiency 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 top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that was better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected into the space. Rumford's layout is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on stone and deflected unnecessary ornamentation. Instead it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on providing quality stone. Stone fireplaces at this time were a sign of prosperity, which to some degree remains the idea today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficacy, based upon the design.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 other flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, where the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a far 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.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical 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. In the USA, several states and local businesses have laws limiting these kinds of fireplaces. Additionally, there are air quality control problems because of the quantity of moisture they release in the room air, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed from the place that is heated, and port all exhaust gasses to the outside of the structure.

As time passes, the purpose of fireplaces has changed from one of necessity to one of interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for heat on cold days and nights, in addition to for cooking. They also functioned as a gathering place inside the house. These fire pits were usually centered within a space, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace designers 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 quality of the materials used in their construction, instead of their size.
By the 1800s newest fireplaces were made up of 2 components, the surround and the add. 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 frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance into homes.Dimplex Winston Electric Fireplace eBay Video
Some fireplace units include a blower that transports more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated space 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 manufactured from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, intended to warm the air. The best method to gauge the output signal of a fireplace is if you detect you're turning the thermostat down or up.
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 improve efficiency, fireplaces can also be altered by adding special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a massive 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 flame is burning. In this time the structure, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the next stage. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Depending on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.dimplex electric fireplaces
