Ancient fire pits were sometimes constructed in the ground, within caves, or in the middle of a hut or home. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated toxic and/or annoying smoke within the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burned with the smoke climbing into the port 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.
Also throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through a room and vent it outside through a wall or roof. These could be put against stone walls, instead of taking up the middle of the space, and this allowed smaller rooms to be warmed.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the problem of fumes, more faithfully venting smoke out. They made it feasible to give the fireplace a draft, and also made it feasible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace that greatly improved the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting out a longer area on top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox that was better at drawing the smoke up and out of the building. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's layout is the foundation for modern fireplaces.
Instead it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on supplying quality gems. Stone fireplaces at this time have been a sign of wealth, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are utilized for its relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficacy, based upon the plan.Historically they were utilized for heating a dwelling, cooking, and heating water for domestic and laundry uses. A fireplace might have the following: a foundation, a hearth, a firebox, a mantelpiece; a chimney crane (utilized in laundry and kitchen fireplaces), a grate, a lintel, a lintel bar, home overmantel, a damper, a smoke chamber, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is frequently a corbeled brick crown, where the casting 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 from the outside of the chimney; rain at the chimney is a far greater problem in chimneys lined with impervious flue tiles or metal liners compared with the traditional masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor incorporated into the cap or crown.
The EPA writes"Smoke may smell good, but it is not good for you.Kinds of fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either wood or gas or retrofit with log inserts or electrical 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, several states and local counties have laws restricting these kinds of fireplaces. They must be properly sized to the area to be heated. There are also air quality management problems due to the quantity of moisture that they release into the room air, and oxygen sensor 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's heated, and vent all exhaust gasses to the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits than contemporary fireplaces. They were used for heat on chilly days and nights, in addition to for cooking. They also served as a gathering place inside the home. These fire pits were generally centered within a space, allowing more people to gather around it.

Many defects were found in ancient fireplace designs. The most famous fireplace performers of the period were the Adam Brothers. They perfected a style of fireplace design that has been used for generations. It was smaller, more brightly lit, with an emphasis on the level of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were composed of two parts, the surround as well as the insert. The encircle comprised of the mantlepiece and sides supports, usually in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron frequently backed with decorative tiles. As well as providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.24quot; Holly Martin Walton Portable Indoor/Outdoor Gel Fireplace PortableFireplace Video
Some fireplace components include 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 can also be increased by means of a fireback, a piece of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complicated concept although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the atmosphere. An open fireplace isn't, and never was, designed to warm the atmosphere. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal way to gauge the output of a fireplace is if you detect you are turning the thermostat down or up.
Most elderly fireplaces have a relatively low efficiency rating. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of 80% (legal minimum necessity such as in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding special heavy fireboxes designed to burn much cleaner and may reach efficiencies as large as 80% in heating the air. These altered fireplaces are often equipped with a large fire window, enabling an efficient heating process in two stages. During the first stage the first heat is offered through a large glass while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the warmth. This heat is then equally radiated for many hours during the next phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.portable fireplace
