Historical fire pits were sometimes constructed in the floor, within caves, or at the center of a hut or dwelling. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor fire pits was that they produced toxic and/or annoying smoke inside the house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or holes in roofs. The medieval great hall typically had a centrally located hearth, where an open fire burnt with all the smoke rising to the port in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be coated so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from spreading through an area and vent it outside via a ceiling or wall. These could be placed against stone walls, instead of taking up the center of the room, and this enabled smaller rooms to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and mostly fixed the problem of fumes, more reliably venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage instantly, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also improved the airflow by pulling air from a cellar and venting out a longer place on top. At the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing up the smoke and from the construction. The shallow design also improved greatly the amount of radiant heat projected into the space. Rumford's design is the basis for modern kitchens.
The Aesthetic movement of the 1870s and 1880s took to a more conventional spectra based on rock and deflected unnecessary ornamentation. Rather it depended 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 placed on providing quality stone. Stone fireplaces now were a symbol of prosperity, which to a degree is still the notion today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are utilized for its relaxing ambiance they create and for heating a space. Modern fireplaces change in heat efficiency, based on the plan.Historically they were 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 other flue allows exhaust to escape.

On the exterior there's often a corbeled brick crown, where the casting courses of brick function as a drip course to keep rainwater from running down the outside walls. A cap, hood, or shroud serves to keep rainwater from the exterior of the chimney; rain in the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, that divides 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 fireplacesArtificial fireplaces are made with sheet metal or glass fire boxes.Electric fireplaces could be built-in replacements for either wood or gas 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 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, several states and local businesses have laws limiting these types of fireplaces. There are also air quality management problems due to the amount of moisture that they release into the room air, and oxygen detector and carbon monoxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the area that's heated, and port all exhaust gasses to the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were more fire pits compared to modern fireplaces.

Many flaws were found in early fireplace designs. Along with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most renowned fireplace performers of this period were the Adam Brothers. They perfected a style of fireplace design that was used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the substances 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 add. The encircle comprised of the mantlepiece and sides affirms, typically in wood, granite or marble. The fit was where the fire burned, and was constructed of cast iron often backed with ornamental tiles. As well as providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance to houses.SpectraFire 39 in.

Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a lower heating load. Fireplace efficiency can also be increased by means of a fireback, a piece of metal which sits behind the flame and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace is not, 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 ideal method to estimate the output signal of a fireplace is if you detect you are turning the thermostat up or down.
Most elderly fireplaces have a comparatively 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 may also be modified by inserting special heavy fireboxes designed to burn cleaner and may reach efficiencies as large as 80% in heating the atmosphere. These modified fireplaces are usually equipped with a massive fire window, allowing an efficient heating process in two stages. During the first stage the first heat is offered through a big glass while the fire is burning. During this time the construction, constructed of refractory bricks, absorbs the warmth. This heat is then evenly radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only offer heat radiated from its surface. Based on temperatures 1 to two daily firings are enough to ensure a constant room temperature.fireplace inserts electric
