Historical fire pits were sometimes constructed in the ground, in 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 toxic and/or annoying smoke inside the house.Fire pits grown into elevated hearths in buildings, but venting smoke depended on open windows or openings in roofs. The great hall typically needed a centrally situated hearth, where an open fire burnt with the smoke climbing into the vent in the roof. Louvers were developed during the Middle Ages to enable the roof vents to be covered so rain and snow would not enter.
Also throughout the Middle Ages, smoke canopies were invented to stop smoke from dispersing a room and vent it outside through a wall or roof. These can be put against stone walls, rather than taking up the middle of the room, and this enabled smaller chambers to be warmed.Chimneys were devised in northern Europe from 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 also made it feasible to place fireplaces in multiple rooms in buildings handily. They did not come into general use immediately, however, since they were more expensive to build and maintain.Benjamin Franklin developed a convection room for the fireplace that greatly improved the efficacy of fireplaces and wood stoves. In addition, he enhanced the airflow by pulling air from a basement and venting out a longer place on top. At 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 building. The shallow design improved greatly the quantity of radiant warmth projected to the space. Rumford's design is the foundation for modern kitchens.
Instead it relied on simple designs with little unnecessary ornamentation. From the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on supplying quality stone. Stone fireplaces at this time were a symbol of wealth, which to a degree remains the notion today.A fireplace is a structure made from brick, stone or metal made to contain a fire. Fireplaces are used for the relaxing ambiance they create and also for heating a space. Modern fireplaces vary in heat efficacy, depending on the design.Historically they have been used for heating a home, cooking, and heating water for laundry and domestic uses.

On the exterior there's 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 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, which divides up all but the rain. A few chimneys have a spark arrestor integrated into the crown or cap.
The EPA writes"Smoke may smell good, but it's not great for you.Types of fireplacesManufactured fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces could be built-in replacements for either gas or wood or retrofit with log inserts or electrical fireboxes.A few kinds are, wall mounted electric fireplaces, electric fireplace stoves, electric 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. Ventless Fireplaces (duct free/room-venting fireplaces) are fueled by either gel, liquid propane, bottled gas or natural gas. In the United States, several states and local businesses have laws restricting these kinds of fireplaces. They must be properly sized to the area to be heated. Additionally, there are air quality control issues due to the amount of moisture that they release in the room air, and oxygen detector and carbon monoxide sensors are safety essentials. Direct vent fireplaces have been fueled by either liquid propane or natural gas. They are completely sealed in the place that is heated, and vent all exhaust gasses into the outside of the structure.

Over time, the purpose of fireplaces has transformed from one of requirement to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They have been used for warmth on chilly days and nights, in addition to for cooking. They also functioned as a gathering place within the house. These fire pits were generally based within a room, allowing more people to gather around it.

Many flaws were found in early fireplace designs. The most renowned fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design that was used for generations. It had been smaller, more brightly lit, with a emphasis on the level of the materials used in their construction, as opposed to their size.
From the 1800s most new fireplaces were made up of two components, the surround and the insert. The encircle comprised of the mantlepiece and sides affirms, usually in wood, granite or marble. The fit was where the fire burnt, 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 homes.Comfort Glow Quartz Electric Fireplace 1500 Watt Heater Stove Flame Log Portable eBay Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the air via convection, leading to a more evenly heated area and a decrease heating load. Fireplace efficiency is also increased with the use of a fireback, a sheet of metal which sits behind the fire and reflects heat back into the room. Firebacks are traditionally produced from cast iron, but are also made from stainless steel. Efficiency is a complicated notion although with open hearth fireplaces. Most efficiency tests consider only the impact of heating of the atmosphere. An open fireplace is not, and never was, designed to warm the atmosphere. The best way to estimate the output signal of a fireplace is in case you notice you're turning the thermostat down or up.
Most elderly 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 improve efficiency, fireplaces can also be altered by adding special heavy fireboxes developed to burn much cleaner and can reach efficiencies as large as 80 percent in heating the atmosphere. These modified fireplaces are usually equipped with a large fire window, enabling an efficient heating system in two phases. During the first phase the first heat is offered through a large glass window while the fire is burning. During this time the construction, built of refractory bricks, absorbs the heat. This heat is then equally radiated for several hours during the next stage. Masonry fireplaces without a glass fire window just offer heat radiated from its surface. Based on outside temperatures 1 to two daily firings are sufficient to guarantee a constant room temperature.electric fireplace heater
