Ancient fire pits were sometimes built in the floor, in caves, or at the center of a hut or dwelling. Evidence of prehistoric, man-made flames exists on all five inhabited continents. The drawback of early indoor flame pits was that they generated toxic and/or irritating smoke within the house.Fire pits grown into elevated hearths in structures, but ventilation smoke depended on open windows or holes in roofs. The great hall typically had a centrally situated hearth, where a open fire burnt with the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so snow and rain would not enter.
Additionally throughout the Middle Ages, smoke canopies were invented to prevent smoke from spreading through an area and vent it out via a wall or roof. These can be placed against rock walls, instead of taking up the middle of the space, and this enabled smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the issue of fumes, more reliably venting smoke outside. They made it feasible to give the fireplace a draft, and made it possible 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 enhanced the efficiency of fireplaces and wood stoves. In addition, he improved the airflow by pulling air from a cellar and venting a lengthier 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 up the smoke and from the construction. The shallow design improved greatly the amount of radiant heat projected to the space. Rumford's layout is the basis for modern fireplaces.
Rather it relied on simple layouts with small 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 have been a symbol of wealth, which to a degree remains the notion today.A fireplace is a construction made from brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and for heating a space. Modern fireplaces vary in heat efficacy, based on the plan.Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (utilized in laundry and kitchen 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 is often a corbeled brick crown, in which the casting courses of brick function as a drip route to keep rainwater from running down the outside walls. A hood, cap, or shroud functions to keep rainwater out of the exterior of the chimney; rain in the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, which soaks up all but the most violent rain. Some chimneys have a spark arrestor integrated into the cap or crown.
The EPA writes"Smoke may smell great, but it is not great for you.Types of fireplacesManufactured fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces can be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A couple of kinds 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. In the USA, some states and local businesses have laws limiting these kinds of fireplaces. There are also air quality control problems because of the amount of moisture they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the area that's heated, and vent all exhaust gasses into the outside of the structure.

As time passes, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were more fire pits compared to modern fireplaces. They were used for warmth on cold days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were usually based within a space, allowing more individuals to collect around it.

Many defects were found in ancient fireplace designs. The most famous fireplace designers of this period were the Adam Brothers. They perfected a style of fireplace design which was used for generations. It had been smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their dimensions.
From the 1800s newest fireplaces were made up of two parts, the surround and the add. The surround comprised of the mantlepiece and sides supports, typically in wood, granite or marble. The insert was where the fire burnt, and was constructed of cast iron often backed with decorative tiles. In addition to providing heat, the fireplaces of the Victorian age were thought to bring a cozy ambiance to homes.Real Flame Silverton Electric Fireplace Reviews Wayfair Video
Some fireplace components include a blower that 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 enhanced by means of a fireback, a piece of metal which 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 concept although with open hearth fireplaces. Most efficacy tests consider just the impact of heating of the air. An open fireplace isn't, and never was, intended to heat the atmosphere. A fireplace with a fireback is a toaster, and has done so as the 15th century. The best way to gauge the output of a fireplace is if you notice you're 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 boost efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are usually equipped with a large fire window, allowing an efficient heating system in two phases. During the first phase the first heat is offered through a large glass window while the flame is burning. In this time period the construction, constructed of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces with no glass fire window just provide heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.fireplace
