Historical fire pits were sometimes constructed in the floor, in caves, or in the middle of a hut or dwelling. Evidence of ancient, man-made flames exists on all five inhabited continents. The drawback of premature indoor flame pits was that they generated hazardous or annoying smoke inside the dwelling.Fire pits grown into raised hearths in buildings, but ventilation smoke depended on open windows or openings in roofs. The medieval great hall typically needed a centrally located hearth, where an open flame burnt with the smoke climbing into the port in the roof. Louvers were developed during 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 spreading through a room and vent it outside through a wall or roof. These can be placed against stone walls, instead of taking up the middle of the room, and this allowed smaller rooms to be warmed.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 possible to give the fireplace a draft, and made it feasible to put fireplaces in multiple rooms in buildings handily. They didn't come into general usage instantly, however, as they were more expensive to develop and maintain.Benjamin Franklin developed a convection room for the fireplace which greatly enhanced 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 at the top. In the later 18th century, Count Rumford designed a fireplace using a tall, shallow firebox which has been better at drawing the smoke up and out of the construction. The shallow design also improved greatly the quantity of radiant warmth projected to the room. Rumford's design is the foundation for modern kitchens.
Instead it relied on simple layouts with small unnecessary ornamentation. In the 1890s the Aesthetic movement gave way to the Arts and Crafts movement, where the emphasis was still placed on providing quality stone. Stone fireplaces now were a symbol of prosperity, which to a degree is still the notion today.A fireplace is a construction made of brick, stone or metal designed to include a fire. Fireplaces are utilized for the relaxing ambiance that they create and also for heating a space. Modern fireplaces vary in heat efficiency, based on the design.Historically they have been utilized for heating a dwelling, cooking, and heating water for laundry and domestic uses. A fire is contained in a firebox or firepit; a chimney or other flue allows exhaust to escape. A fireplace may have the following: a base, a hearth, a firebox, a mantelpiece; a chimney (used in kitchen and laundry fireplaces), a grate, a lintel, a lintel pub, house overmantel, a damper, a smoke room, a neck, a flue, and a chimney filter or afterburner.

On the exterior there is 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 hood, cap, or shroud serves 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 standard 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 great, but it's not good for you.Kinds of fireplacesManufactured fireplaces are made with sheet metal or glass flame boxes.Electric fireplaces could be built-in replacements for wood or gas or retrofit with log inserts or electrical fireboxes.A couple of types are, wall mounted electric fireplaces, electric fireplace stoves, electric mantel fireplaces and fixed or free standing gas fireplaces.
In the USA, some states and local businesses have laws restricting these types of fireplaces. They need to be properly sized to the area to be heated. Additionally, there are air quality control issues due to the quantity of moisture they release into the room air, and oxygen sensor and carbon dioxide sensors are security essentials. Direct vent fireplaces are fueled by liquid propane or natural gas. They are totally sealed in the place that is heated, and vent all exhaust gasses to the outside of the structure.

As time passes, the intent behind fireplaces has changed from one of necessity to one of visual interest. Early ones were fire pits compared to contemporary fireplaces. They were used for warmth on chilly days and nights, in addition to 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 gather around it.

Many defects were found in ancient fireplace designs. Along with the Industrial Revolution, came large scale housing developments, requiring a standardization of fireplaces. The most famous fireplace designers of this period were the Adam Brothers. They perfected a kind of fireplace design which was used for generations. It was smaller, more brightly colored, with a emphasis on the quality of the substances used in their construction, instead of their size.
From the 1800s most new fireplaces were made up of 2 parts, the surround and the add. The surround consisted of the mantlepiece and sides supports, usually in wood, marble or granite. The insert was fire burnt, and was built of cast iron often backed with ornamental tiles. In addition to providing warmth, the fireplaces of the Victorian age were thought to bring a cozy ambiance into houses.Dimplex Brookings TV Stand with Electric Fireplace eBay Video
Some fireplace components incorporate a blower which transports more of the fireplace's heat to the air via convection, resulting in a more evenly heated area and a decrease heating load. Fireplace efficiency can also be increased by means of a fireback, a sheet 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 complex notion 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 warm the atmosphere. The ideal method to estimate the output signal of a fireplace is if you detect you're turning the thermostat up or down.
Most elderly fireplaces have a relatively low efficiency score. Standard, contemporary, weatherproof masonry fireplaces still possess an efficiency rating of 80% (legal minimum requirement such as in Salzburg/Austria). To improve efficiency, fireplaces may also be modified by adding special heavy fireboxes developed to burn cleaner and can reach efficiencies as large as 80% in heating the air. These modified fireplaces are often equipped with a massive fire window, allowing an efficient heating process in two stages. During the first phase the initial heat is provided through a big glass window while the flame is burning. In this time period the construction, built of refractory bricks, absorbs the heat. This warmth is then equally radiated for several hours during the second stage. Masonry fireplaces without a glass fire window only provide heat radiated from the surface. Based on temperatures 1 to 2 daily firings are enough to guarantee a constant room temperature.tv stand with electric fireplace
