Ancient fire pits were sometimes built in the ground, within caves, or in the center of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor fire pits was that they produced toxic and/or annoying smoke within the house.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where a open flame burned with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it outside through a wall or roof. These could be put against rock walls, rather than taking up the center of the room, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it possible to put fireplaces in numerous rooms in buildings conveniently. They did not come into general use immediately, however, since they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, raised the grate of the fireplace, improving the airflow and venting system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace that greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a longer place on very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which was better at drawing up the smoke and from the building. The shallow design improved greatly the quantity of radiant warmth projected to the room. Rumford's design is the foundation for modern kitchens.
Instead it depended on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces now were a sign of wealth, which to a degree is still the notion today.A fireplace is a structure made of brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance that they create and for heating a room. Modern fireplaces vary in heat efficiency, depending upon the design.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there is often a corbeled brick crown, where the casting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater from the outside of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that divides up all but the rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, some states and local counties have laws limiting these kinds of fireplaces. They must be suitably sized to the area to be heated. There are also air quality management issues due to the quantity of moisture they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are security 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 into the exterior of the structure.

Over time, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits than modern fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also functioned as a gathering place inside the home. These fire pits were generally centered within a space, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most famous fireplace performers of this time were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It had been smaller, more brightly lit, with a emphasis on the quality of the substances used in their construction, as opposed to their size.
From the 1800s most new fireplaces were composed of two parts, the surround and the insert. The surround comprised of the mantlepiece and sides supports, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron often backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were believed to bring a cozy ambiance to homes.Fireplace Accessories Fire Tools Jøtul Video
Some fireplace components 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 enhanced with the use 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 can also be manufactured from stainless steel. Efficiency is a complicated notion 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, intended to warm the air. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best way to estimate the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most older fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces may also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the air. These modified fireplaces are often 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 large glass while the fire is burning. During this time the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for many hours during the second phase. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Based on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace set
