Ancient fire pits were sometimes constructed from the floor, within caves, or in the middle of a hut or home. Evidence of ancient, man-made flames is present on all five inhabited continents. The disadvantage of premature indoor flame pits was that they generated toxic and/or irritating smoke within the house.Fire pits grown into elevated hearths in structures, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically had a centrally situated hearth, where a open flame burnt 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 snow and rain would not enter.
Additionally during the Middle Ages, smoke canopies were devised to stop smoke from spreading through an area and vent it outside through a wall or roof. These could be placed against stone walls, instead of taking up the center of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general use immediately, however, as they were expensive to develop and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also improved the airflow by pulling air from a basement and venting a lengthier place on top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which was better at drawing up the smoke and out of the construction. The shallow design also improved greatly the quantity of radiant heat projected into the room. Rumford's layout is the foundation for modern fireplaces.
The Aesthetic movement of the 1870s and 1880s took to a more traditional spectra based on stone and also deflected unnecessary ornamentation. Instead 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 supplying quality gems. Stone fireplaces at this time have been a sign of prosperity, which to a degree is still the notion today.A fireplace is a structure made from brick, stone or metal designed to contain a fire. Fireplaces are used for its relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficacy, depending upon the plan.Historically they have been used for heating a home, cooking, and heating water for domestic and laundry uses. A fireplace may have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel bar, house overmantel, a damper, a smoke chamber, a throat, 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 function as a drip route to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the outside of the chimney; rain at the chimney is a much greater difficulty in chimneys lined with impervious flue tiles or metallic liners compared with the traditional masonry chimney, that soaks up all but the most violent rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for gas or wood or retrofit with log inserts or electric fireboxes.A few types are, wall mounted electric fireplaces, electric fireplace stoves, electrical mantel fireplaces and fixed or free standing gas 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, several states and local businesses have laws limiting these types of fireplaces. Additionally, there are air quality control problems because of the amount of moisture they discharge in the room air, and oxygen sensor and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and vent all exhaust gasses to the outside of the structure.
All About Fireplaces and Fireplace Surrounds DIY
Over time, the purpose of fireplaces has changed from one of requirement to one of visual interest. Early ones were more fire pits than contemporary fireplaces. They have been used for warmth on cold days and nights, as well as for cooking. They also served as a gathering place within the home. These fire pits were generally centered within a space, allowing more individuals to collect around it.

Many flaws were found in ancient fireplace designs. The most famous fireplace performers of the period 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, instead of their dimensions.
From the 1800s most new fireplaces were composed of 2 components, the surround and the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was where the fire burnt, and was built of cast iron frequently backed with decorative tiles. As well as providing heat, the fireplaces of the Victorian age were believed to add a cozy ambiance into houses.Fireplace Surround Kits Ideas HomesFeed Video
Some fireplace components 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 piece of metal that sits behind the flame 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 efficiency tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the air. The best method to gauge the output of a fireplace is if you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high 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 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 next stage. Masonry fireplaces with no glass fire window just offer heat radiated from its surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace surround
