Historical fire pits were sometimes constructed in the ground, within caves, or in the center of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they produced toxic and/or irritating smoke within the dwelling.Fire pits developed into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally situated hearth, where an open flame 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 covered so rain and snow wouldn't enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it outside via a wall or roof. These can be put against rock walls, instead of taking up the center of the room, and this allowed smaller chambers to be warmed.Chimneys were devised in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings handily. They didn't come into general use instantly, however, as they were more expensive to build and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a basement and venting a longer area at the very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing the smoke up and from the building. The shallow design also improved greatly the amount of radiant warmth projected to the space. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on rock and also deflected unnecessary ornamentation. Rather it relied on simple designs with small unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was placed on supplying quality gems. Stone fireplaces now were a symbol of wealth, which to a degree remains the idea today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending upon the plan.Historically they have been used for heating a dwelling, 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.

On the exterior there is often a corbeled brick crown, where the projecting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the outside of the chimney; rain at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces could pose a significant health threat. The EPA writes"Smoke may smell great, but it's not good for you.Types of fireplacesManufactured fireplaces are made out of sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
In the United States, several states and local businesses have laws restricting these kinds of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality management problems due to the amount of moisture that they discharge in the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed from the place that's heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has changed from one of requirement to one of interest. Early ones were more fire pits than contemporary fireplaces. They were 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 room, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. The most famous fireplace designers of this time were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly colored, with an emphasis on the quality of the substances used in their construction, as opposed to their dimensions.
From the 1800s newest fireplaces were made up of 2 parts, the surround as well as the add. The surround consisted of the mantlepiece and sides supports, usually in wood, granite or marble. The insert was where the fire burnt, and was constructed of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were believed to add a cozy ambiance into homes.Alpha 36S Direct Vent Gas Fireplace Gas Fireplaces Video
Some fireplace components incorporate a blower which transfers 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 enhanced by means of a fireback, a piece of metal that sits behind the flame and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also manufactured from stainless steel. Efficiency is a complex concept although with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. The best method to estimate the output of a fireplace is in case you detect you're turning the thermostat down or up.
Most elderly 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 improve efficiency, fireplaces can also be altered by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as high as 80 percent in heating the air. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating system in two phases. During the first stage the first heat is offered through a big glass while the fire is burning. During this time the structure, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for many hours during the next stage. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace pictures
