Ancient fire pits were sometimes built from the floor, within caves, or at the middle of a hut or home. Evidence of ancient, man-made fires exists on all five inhabited continents. The drawback of premature indoor fire pits was that they produced hazardous or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in structures, but venting smoke relied on open windows or openings in roofs. The great hall typically needed 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 allow the roof vents to be coated so rain and snow wouldn't enter.

Also during the Middle Ages, smoke canopies were invented to stop smoke from spreading through a room and vent it out via a ceiling or wall. These can be placed against rock walls, instead of taking up the middle of the space, and this allowed smaller chambers to be heated.Chimneys were invented in northern Europe from the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke out. They made it feasible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage instantly, however, as they were more expensive to develop and maintain.

In 1678 Prince Rupert, nephew of Charles I, increased the grate of the fireplace, improving the venting and airflow system. The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection room for the fireplace which greatly enhanced the efficacy of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting out a lengthier area on very top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox that has been better at drawing up the smoke and from the building. The shallow design also improved greatly the amount of radiant heat projected into the room. Rumford's layout is the basis for modern kitchens.

Rather it relied on simple designs with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way into the Arts and Crafts movement, where the emphasis was placed on providing quality stone. Stone fireplaces at this time were a symbol of prosperity, which to a degree is still the notion today.A fireplace is a structure made of 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 efficiency, based upon the design.

Historically they have been utilized for heating a home, cooking, and heating water for domestic and laundry uses. A fire is contained in a firebox or firepit; a chimney or alternative flue allows exhaust to escape.

On the exterior there's frequently a corbeled brick crown, where the casting courses of brick act as a drip route to keep rainwater from running down the exterior walls. A hood, cap, or shroud functions to keep rainwater out of the outside of the chimney; rain at the chimney is a far larger difficulty in chimneys lined with impervious flue tiles or metal liners than with the standard masonry chimney, which divides up all but the most violent rain. Some chimneys have a spark arrestor integrated into the crown or cap.

Organizations like the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to different studies, fireplaces can pose a substantial health threat. The EPA writes"Smoke may smell good, but it is not great for you.

Kinds of fireplacesManufactured fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either wood or gas or retrofit with log inserts or electrical 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. In the United States, several states and local businesses have laws limiting these types of fireplaces. They need to be suitably sized to the area to be heated. Additionally, there are air quality management issues because of the amount of moisture that they release into the room atmosphere, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by 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.

AccessoriesA vast range of accessories are used with fireplaces, which range between states, regions, and historical periods. For the interior, common in recent Western cultures comprise grates, fireguards, log boxes, andirons, bark baskets, along with fire puppies, all which cradle fuel and accelerate burning. A grate (or flame grate) is a frame, usually of iron bars, to retain fuel for a fire. Heavy metal firebacks are sometimes used to capture and re-radiate warmth, to safeguard the rear of the fireplace, and as decoration. Fenders are low metallic frames placed before the fireplace to contain embers, soot and ash. For fireplace tending, tools include pokers, bellows, tongs, shovels, brushes and tool racks.

As time passes, the purpose of fireplaces has transformed from one of necessity to one of interest. Early ones were fire pits than modern fireplaces.

Some fireplace components incorporate a blower that transports more of the fireplace's heat to the air via convection, leading to a more evenly heated space and a decrease heating load. Fireplace efficiency is also 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 are also manufactured from stainless steel. Efficiency is a complicated notion though with open hearth fireplaces. Most efficiency tests consider just the effect of heating of the atmosphere. An open fireplace isn't, and never was, designed to heat the atmosphere. The best method to gauge the output of a fireplace is in case you notice you're turning the thermostat down or up.

Most elderly fireplaces have a relatively 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 boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn much cleaner and can reach efficiencies as high as 80% in heating the air. These altered fireplaces are usually equipped with a massive fire window, enabling an efficient heating process in two phases. During the first phase the initial heat is provided through a big glass window while the fire is burning. In this time the structure, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for many hours during the next stage. Masonry fireplaces with no glass fire window just offer heat radiated from the surface. Based on outside temperatures 1 to 2 daily firings are sufficient to ensure a constant room temperature.fireplace mantels
