Historical fire pits were sometimes constructed in the ground, in caves, or at the center of a hut or home. Evidence of ancient, man-made fires is present on all five inhabited continents. The disadvantage of premature indoor fire pits was that they generated toxic and/or annoying smoke within the dwelling.Fire pits grown into raised hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open fire burned 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 rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from dispersing an area and vent it out through a wall or roof. These could be put against rock walls, instead of taking up the middle of the space, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage instantly, however, since they were more expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting out a longer area on very top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that was better at drawing the smoke up and out of the construction. The shallow design improved greatly the amount of radiant warmth projected to the space. Rumford's design is the foundation for modern kitchens.
Instead 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 still placed on supplying quality stone. Stone fireplaces at this time were a symbol of prosperity, which to a degree remains the notion today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they have been utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses.

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 exterior walls. A hood, cap, or shroud functions to keep rainwater from the exterior of the chimney; rain in the chimney is a much larger 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 cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces could pose a substantial health threat. The EPA writes"Smoke may smell great, but it's not great for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electric 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, some states and local counties have laws limiting these types of fireplaces. There are also air quality management problems because of the quantity of moisture they discharge in the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and port all exhaust gasses to the outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits compared to contemporary fireplaces. They were used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were usually centered within a space, allowing more people to gather around it.

Many flaws were found in ancient fireplace designs. Together with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly lit, 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 encircle comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was fire burnt, and was constructed of cast iron often backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance into homes.Gas fireplace inserts Jøtul Video
Some fireplace units include a blower which transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a decrease heating load. Fireplace efficiency can also be increased with the use of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but can also be made from stainless steel. Efficiency is a complex concept though with open hearth fireplaces. Most efficacy tests consider only the effect of heating of the air. An open fireplace isn't, and never was, designed to warm the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The ideal method to gauge the output signal of a fireplace is in case you notice you're turning the thermostat up or down.
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 for example in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn cleaner and may reach efficiencies as large as 80% in heating the air. These altered fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first phase the initial heat is offered through a big glass while the fire is burning. During this time period the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the second stage. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.gas insert fireplace
