Ancient fire pits were sometimes constructed from the floor, in caves, or in the center of a hut or dwelling. Evidence of prehistoric, man-made fires is present on all five inhabited continents. The drawback of early indoor fire pits was that they generated hazardous or annoying smoke within the dwelling.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The great hall typically needed a centrally located hearth, where a open fire burnt with the smoke rising to the vent in the roof. Louvers were developed throughout the Middle Ages to allow the roof vents to be covered so snow and rain wouldn't enter.
Also throughout the Middle Ages, smoke canopies were devised to prevent smoke from dispersing a room and vent it outside via a wall or roof. These can be put against stone walls, instead of taking up the middle of the space, and this allowed smaller chambers to be warmed.Chimneys were invented in northern Europe in the 11th or 12th centuries and largely fixed the issue of fumes, more faithfully venting smoke outside. They made it possible to give the fireplace a draft, and also made it possible to put fireplaces in multiple rooms in buildings conveniently. They didn't come into general usage instantly, however, since they were more expensive to develop and maintain.The 18th century saw two major developments in the history of fireplaces. Benjamin Franklin developed a convection chamber for the fireplace which greatly improved the efficiency of fireplaces and wood stoves. He also enhanced the airflow by pulling air from a cellar and venting a lengthier place on very top. In the later 18th century, Count Rumford made a fireplace with a tall, shallow firebox which was better at drawing the smoke up and from the building. The shallow design improved greatly the amount of radiant heat projected into the space. Rumford's layout is the basis for modern kitchens.
Rather it relied on simple designs with little unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, in which the emphasis was placed on providing quality stone. Stone fireplaces now were a sign of wealth, which to a degree remains the notion today.A fireplace is a construction made from brick, stone or metal designed 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 utilized 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 alternative flue allows exhaust to escape.

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 outside walls. A cap, hood, or shroud functions to keep rainwater out of the exterior of the chimney; rain at the chimney is a much greater problem in chimneys lined with impervious flue tiles or metal liners than with the traditional masonry chimney, which soaks up all but the rain. A few chimneys have a spark arrestor incorporated into the crown or cap.
The EPA writes"Smoke may smell great, but it's not great for you.Types of fireplacesManufactured fireplaces are made with sheet glass or metal fire boxes.Electric fireplaces can be built-in replacements for gas or wood or retrofit with log inserts or electrical fireboxes.
Masonry and prefabricated fireplaces can be fueled by wood, natural gas, biomass and gas fuel sources. In the USA, some states and local businesses have laws restricting these types of fireplaces. There are also air quality control problems due to the quantity of moisture they discharge in the room atmosphere, and oxygen sensor and carbon dioxide sensors are safety essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and port all exhaust gasses into the exterior of the structure.

As time passes, the intent behind fireplaces has transformed 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, in addition to for cooking. They also functioned as a gathering place inside the home. These fire pits were usually based within a space, allowing more individuals to gather around it.

Many flaws were found in ancient fireplace designs. The most renowned fireplace designers of the time were the Adam Brothers. They perfected a kind of fireplace design which has been 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 dimensions.
From the 1800s most new fireplaces were made up of two parts, the surround and the insert. The encircle consisted of the mantlepiece and sides affirms, typically in wood, marble or granite. The fit was where the fire burnt, and was built of cast iron frequently backed with ornamental tiles. As well as providing heat, the fireplaces of the Victorian era were believed to bring a cozy ambiance into homes.Best 25+ Zero clearance fireplace ideas on Pinterest Fireplace heater, Indoor gas fireplace Video
Some fireplace components incorporate a blower which transfers more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a lower heating load. Fireplace efficiency can also be 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 made from cast iron, but can also be manufactured from stainless steel. Efficiency is a complicated concept though with open hearth fireplaces. Most efficacy tests consider only the impact of heating of the air. An open fireplace isn't, and never was, intended to heat the air. A fireplace with a fireback is a radiant heater, and has done so as the 15th century. The ideal way to estimate the output signal of a fireplace is in case you detect you are turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, modern, wood-burning masonry fireplaces though have an efficiency rating of at least 80% (legal minimum requirement for example in Salzburg/Austria). To improve efficiency, fireplaces can also be modified by adding 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 large fire window, allowing an efficient heating process in two stages. During the first phase the first heat is offered through a big glass while the flame is burning. In this time the construction, built of refractory bricks, absorbs the warmth. This warmth is then equally radiated for many hours during the next phase. Masonry fireplaces without a glass fire window only provide heat radiated from its surface. Based on temperatures 1 to 2 daily firings are sufficient to guarantee a constant room temperature.zero clearance fireplace
