Historical fire pits were sometimes constructed from the floor, within caves, or at the center of a hut or home. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of early indoor flame pits was that they produced hazardous or irritating smoke inside the dwelling.Fire pits developed into raised hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically had a centrally situated hearth, where a open fire burnt with the smoke climbing into the vent in the roof. Louvers were developed throughout the Middle Ages to enable the roof vents to be covered so rain and snow wouldn't enter.
Additionally during the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside via a wall or roof. These can be placed against stone walls, rather than taking up the middle of the space, and this enabled 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 reliably venting smoke outside. They made it possible to provide the fireplace a draft, and made it possible to place fireplaces in multiple rooms in buildings handily. They didn't come into general use immediately, however, as they were expensive to build 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 important 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 improved the airflow by pulling air from a cellar and venting a longer place at the very top. At the later 18th century, Count Rumford made a fireplace using a tall, shallow firebox that has been better at drawing the smoke up and from the construction. The shallow design also improved greatly the quantity of radiant warmth projected to the space. Rumford's layout is the foundation for modern kitchens.
Instead it depended 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 still placed on supplying quality stone. Stone fireplaces now have been a symbol of wealth, which to some degree is still the notion today.A fireplace is a construction made of brick, stone or metal made to contain a fire. Fireplaces are utilized for the relaxing ambiance they create and also for heating a room. Modern fireplaces change in heat efficiency, depending upon the design.Historically they were used for heating a dwelling, cooking, and heating water for domestic and laundry uses.

On the exterior there is frequently a corbeled brick crown, in which the projecting courses of brick act as a drip course to keep rainwater from running down the exterior walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a much 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. A few chimneys have a spark arrestor incorporated into the cap or crown.
Organizations such as the United States Environmental Protection Agency and the Washington Department of Ecology warn that, according to various studies, fireplaces can pose a substantial health risk. The EPA writes"Smoke may smell good, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made out of sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electric fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing electric fireplaces.
Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by gel, liquid propane, bottled gas or natural gas. In the United States, some states and local businesses have laws restricting these types of fireplaces. Additionally, there are air quality management problems due to the amount of moisture that they release into the room air, and oxygen detector and carbon dioxide sensors are safety essentials. Direct vent fireplaces have been fueled by liquid propane or natural gas. They are completely sealed in the place that's heated, and vent all exhaust gasses into the exterior of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of interest. Early ones were fire pits than modern fireplaces. They have been used for heat on chilly days and nights, as well as for cooking. They also served as a gathering place inside the home. These fire pits were generally based within a room, allowing more people to collect around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of the period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It had been smaller, more brightly colored, with an emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s newest fireplaces were made up of 2 parts, the surround and the insert. The surround consisted of the mantlepiece and sides affirms, usually in wood, marble or granite. The insert was fire burned, and was built of cast iron frequently backed with decorative tiles. In addition to providing warmth, the fireplaces of the Victorian era were thought to add a cozy ambiance into homes.Gas Fireplace Santa Rosa, Gas Fireplace Insert Warming Trends Video
Some fireplace components include a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated space and a lower heating load. Fireplace efficiency is also enhanced 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 concept although with open hearth fireplaces. Most efficiency tests consider just the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to heat the air. 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 rating. 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 may also be modified by inserting special heavy fireboxes developed to burn much cleaner and may reach efficiencies as high as 80 percent in heating the air. These altered fireplaces are often equipped with a massive fire window, allowing an efficient heating system in two phases. During the first phase the first heat is offered through a big glass window while the flame is burning. During this time the structure, built of refractory bricks, absorbs the warmth. This warmth is then evenly radiated for several hours during the next stage. Masonry fireplaces with no glass fire window only provide heat radiated from the surface. Depending on temperatures 1 to 2 daily firings are enough to ensure a constant room temperature.gas fireplaces
