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 flames exists on all five inhabited continents. The drawback of early indoor fire pits was that they generated hazardous or irritating smoke inside the dwelling.Fire pits grown into elevated hearths in buildings, but venting smoke relied on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where a open fire 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 coated so rain and snow wouldn't enter.

Additionally during the Middle Ages, smoke canopies were devised to stop smoke from dispersing an area and vent it out via a ceiling or wall. These could be put against stone walls, instead of taking up the center of the room, and this allowed smaller rooms to be heated.Chimneys were devised in northern Europe in the 11th or 12th centuries and largely fixed the problem of fumes, more reliably venting smoke outside. They made it feasible to provide the fireplace a draft, and also made it possible to place fireplaces in numerous rooms in buildings handily. They didn't come into general use immediately, 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 airflow and venting system. The 18th century saw two important developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly enhanced the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a basement and venting a lengthier place at the very top. In the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and out of the construction. The shallow design also improved greatly the amount of radiant warmth projected to the room. Rumford's design is the basis for modern kitchens.

Rather it depended on simple layouts with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was still placed on supplying quality gems. Stone fireplaces at this time were a sign of wealth, which to some degree is still the idea today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a room. Modern fireplaces vary in heat efficiency, depending upon the plan.

Historically they were used for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there's often a corbeled brick crown, where the projecting courses of brick function as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud serves to keep rainwater out of the outside of the chimney; rain at the chimney is a far greater difficulty in chimneys lined with impervious flue tiles or metal liners compared with the standard masonry chimney, that soaks up all but the rain. Some chimneys have a spark arrestor integrated into the crown or cap.

Types of fireplacesManufactured 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 electric fireboxes.

Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the USA, several states and local businesses have laws limiting these kinds of fireplaces. Additionally, there are air quality control issues because of the amount of moisture they release in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed from the area that is heated, and port all exhaust gasses into the outside of the structure.

AccessoriesA wide assortment of accessories are used with fireplaces, ranging between states, regions, and historical periods. For the inside, common in current Western cultures comprise grates, fireguards, log boxes, andirons, bark baskets, and fire puppies, all which cradle gas and quicken burning. A grate (or flame grate) is a frame, usually of iron bars, to retain fuel to your fire. Heavy metal firebacks are sometimes utilized to catch and re-radiate warmth, to safeguard the rear of the fireplace, and as decoration. Fenders are low metal frames set in front of the fireplace to include embers, soot and ashes. For fireplace tending, tools include pokers, bellows, tongs, shovels, brushes and tool racks.

Over time, the purpose of fireplaces has changed from one of necessity to one of visual interest. Early ones were more fire pits than modern fireplaces. They have been used for warmth on chilly days and nights, as well as for cooking. They also functioned as a gathering place inside the house. These fire pits were generally centered within a room, allowing more individuals to collect around it.

Some fireplace components incorporate a blower that transports more of the fireplace's heat to the atmosphere via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be increased by means of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally made from cast iron, but are also made from stainless steel. Efficiency is a complex notion though with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the air. An open fireplace is not, and never was, designed to warm the air. A fireplace with a fireback is a radiant heater, and has done so since the 15th century. The best way to gauge the output of a fireplace is if you detect you're 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 at least 80% (legal minimum requirement such as in Salzburg/Austria). To boost efficiency, fireplaces can also be modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as large as 80 percent in heating the air. These modified fireplaces are often equipped with a massive fire window, enabling an efficient heating process in two phases. During the first stage the first heat is provided through a big glass window while the flame is burning. During this time period the construction, built of refractory bricks, absorbs the heat. This heat is then evenly radiated for several hours during the second phase. Masonry fireplaces with no glass fire window only offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are enough to guarantee a constant room temperature.lennox fireplaces
