Historical fire pits were sometimes built in the ground, in caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The disadvantage of early indoor flame pits was that they generated toxic and/or annoying smoke within the house.Fire pits developed into raised hearths in buildings, but ventilation smoke relied on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where a open fire burnt with all 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 snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were devised to prevent smoke from spreading through an area and vent it outside through a ceiling or wall. These can be put against stone walls, instead of taking up the middle of the space, and this enabled 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 reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings conveniently. They did not come into general use immediately, however, as they were expensive to develop and maintain.In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the airflow and venting system. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a longer place on top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox which has been better at drawing up the smoke and out of the construction. The shallow design improved greatly the quantity of radiant warmth projected into the room. Rumford's layout is the foundation for modern kitchens.
Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces at this time were a symbol of prosperity, 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 its relaxing ambiance they create and also for heating a space. Modern fireplaces change in heat efficiency, based upon the design.Historically they were used for heating a home, 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 is often a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, which divides up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made with sheet glass or metal flame boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, some states and local counties have laws restricting these types of fireplaces. There are also air quality control problems due to the quantity of moisture they discharge into the room air, 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 from the area that is heated, and port all exhaust gasses to the outside of the structure.

As time passes, the intent behind fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits than contemporary fireplaces. They were used for heat on cold days and nights, as well as for cooking. They also served as a gathering place within the house. These fire pits were usually based within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, necessitating a standardization of fireplaces. The most renowned fireplace performers of this time were the Adam Brothers. They perfected a kind of fireplace design which has been used for generations. It had been smaller, more brightly colored, with a emphasis on the level of the materials used in their construction, instead of their size.
From the 1800s most new fireplaces were made up of 2 parts, the surround as well as the insert. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were believed to bring a cozy ambiance to homes.Furnace and Air Conditioning Repair in Stillwater MN Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a lower heating load. Fireplace efficiency is also 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 are also manufactured from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the air. An open fireplace isn't, and never was, designed to heat the air. A fireplace with a fireback is a toaster, and has done so since the 15th century. The ideal method to estimate the output of a fireplace is if you detect you're turning the thermostat down or up.
Most elderly fireplaces have a comparatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum requirement for example in Salzburg/Austria). To boost efficiency, fireplaces can also be altered by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the atmosphere. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two phases. During the first phase the initial heat is provided through a big glass window while the flame is burning. During this time the construction, built of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the next phase. Masonry fireplaces without a glass fire window only offer heat radiated from the surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.gas fireplace repair
