Ancient fire pits were sometimes built in the ground, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated hazardous or irritating smoke within the house.Fire pits developed into elevated hearths in structures, but venting smoke depended on open windows or openings in roofs. The medieval great hall typically had a centrally situated hearth, where an open fire burned with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so rain and snow would not enter.
Also during the Middle Ages, smoke canopies were devised to stop smoke from dispersing a room and vent it out through a ceiling or wall. These could be put against rock walls, instead of taking up the middle of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe from the 11th or 12th centuries and mostly fixed the issue of fumes, more faithfully venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to place fireplaces in numerous rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting out a lengthier place at the top. At the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and from the building. The shallow design improved greatly the amount of radiant warmth projected to the space. Rumford's design is the basis for modern kitchens.
Instead it relied on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on supplying quality stone. Stone fireplaces now were a symbol of wealth, which to some degree is still the notion today.A fireplace is a structure made from brick, stone or metal designed to include a fire. Fireplaces are used for its relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, depending on the design.Historically they were utilized for heating a dwelling, cooking, and heating water for laundry and domestic 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 bar, 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, in which the projecting courses of brick act as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater out of the exterior of the chimney; rain at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metallic liners than with the traditional masonry chimney, that soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a significant health threat. The EPA writes"Smoke may smell good, but it's not great for you.Kinds of fireplacesManufactured fireplaces are made with 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 few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas fireplaces.
In the United States, several states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control issues due to the quantity of moisture they discharge in the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are completely sealed from the place that's heated, and vent all exhaust gasses into the exterior of the structure.
The Anatomy of a Fireplace: Flues, Chimneys and More DIY
As time passes, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits than modern fireplaces. They have been used for heat on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally centered within a space, allowing more people to gather around it.

Many defects were found in early fireplace designs. The most famous fireplace designers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It was smaller, more brightly colored, with a emphasis on the level of the substances used in their construction, instead of their size.
From the 1800s most new fireplaces were made up of two components, the surround and the insert. The encircle comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burned, and was built of cast iron often backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian era were believed to add a cozy ambiance to houses.Good Fireplace Chimney Flute — Quickinfoway Interior Ideas Video
Some fireplace components include a blower that transfers more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also increased by means of a fireback, a piece of metal which sits behind the flame 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 although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm the air. The best way to gauge the output of a fireplace is if you detect you are 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 at least 80% (legal minimum necessity 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 large as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, enabling an efficient heating system in two phases. During the first phase the first heat is offered through a big glass while the flame is burning. In this time the structure, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Depending on temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.fireplace flue
