Ancient fire pits were sometimes constructed from the floor, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they produced hazardous or irritating smoke within the house.Fire pits developed into raised hearths in structures, but venting smoke relied on open windows or holes in roofs. The great hall typically had a centrally located hearth, where an open fire burnt with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it out via a ceiling or wall. These can be put against stone walls, instead of taking up the center of the room, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings handily. They didn't come into general usage instantly, however, as they were more expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a lengthier area at the very top. In the later 18th century, Count Rumford designed a fireplace with a tall, shallow firebox that has been better at drawing the smoke up and from the building. The shallow design also improved greatly the quantity of radiant heat projected into the space. Rumford's layout is the basis for modern fireplaces.
Rather it relied on simple designs with little 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 were a sign of prosperity, which to some degree remains the idea today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficacy, depending upon the design.Historically they have been used 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. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick act 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 outside 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, 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 good, but it's not good for you.Types of fireplacesArtificial fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A few 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. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws limiting these types of fireplaces. There are also air quality control issues due to the amount of moisture they discharge in the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are totally sealed in the place that's heated, and vent all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place inside the house. These fire pits were generally based within a space, allowing more people to collect around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a style of fireplace design which has been used for generations. It was smaller, more brightly lit, with a emphasis on the quality of the materials used in their construction, as opposed to their size.
From the 1800s newest fireplaces were made up of 2 parts, the surround as well as the insert. The encircle consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were thought to bring a cozy ambiance to homes.Fireplace Surround Ideas How to Choose a Good Wood Fireplace Surround YouTube Video
Some fireplace units include a blower which transfers more of the fireplace's heat to the atmosphere via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased by means of a fireback, a sheet of metal that sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complex 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 atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The ideal way to gauge the output signal of a fireplace is in case you notice you are turning the thermostat up or down.
Most older fireplaces have a comparatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be altered by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as high as 80% in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two stages. During the first stage the first heat is offered through a large glass while the fire is burning. During this time period the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for several hours during the next phase. Masonry fireplaces with no glass fire window only provide heat radiated from its surface. Based on outside temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace surround ideas
