Ancient fire pits were sometimes constructed from the ground, in 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 fire pits was that they produced toxic and/or irritating smoke inside the house.Fire pits grown into raised hearths in structures, but ventilation smoke depended on open windows or openings in roofs. The great hall typically had a centrally located hearth, where an open flame burnt 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 through a ceiling or wall. These could be placed against stone walls, instead of taking up the middle of the room, and this enabled 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 reliably venting smoke out. They made it possible to give the fireplace a draft, and made it possible to place fireplaces in numerous rooms in buildings handily. They did not come into general use instantly, however, since they were more expensive to build and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the venting and airflow system. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a lengthier place on top. At the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox which was better at drawing up the smoke and from the building. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took on a more conventional spectra based on stone and also deflected unnecessary ornamentation. Instead it depended on simple layouts with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces now have been a sign of prosperity, which to some degree remains the notion today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces change in heat efficacy, depending on the plan.Historically they have been utilized 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 (used in laundry and kitchen fireplaces), a grate, a lintel, a lintel pub, home overmantel, a damper, a smoke room, a throat, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, in which the projecting courses of brick function 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 greater problem in chimneys lined with impervious flue tiles or metallic liners than with the standard masonry chimney, which divides up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing electric fireplaces.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and propane fuel sources. In the USA, several states and local counties have laws limiting these kinds of fireplaces. There are also air quality control issues due to the amount of moisture that they discharge in the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the place that is heated, and vent all exhaust gasses into the outside 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 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 inside the house. These fire pits were usually centered within a room, allowing more individuals to gather around it.

Many defects were found in early fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of this period were the Adam Brothers. They perfected a kind of fireplace design which has been 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 newest fireplaces were composed of two parts, the surround and the add. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The fit was fire burned, and was constructed of cast iron often backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.Fireplace Accessories You Need Asheville NC Environmental Video
Some fireplace components incorporate a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced by means 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 are also manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal 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 rating. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the air. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two phases. During the first phase the first heat is offered through a big glass while the fire is burning. In this time period the structure, constructed of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for many hours during the second stage. Masonry fireplaces with no glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to ensure a constant room temperature.fireplace accessories
