Radiant floor heating definitions

Radiant floor heating is a temperature no higher than 60 ° C hot water circulating embedded in the floor under the coil system, heating the entire floor evenly through the ground a heating mode of the heat radiation to the interior.
Radiant floor heating is not a mystery, as early as 1300 BC, Turkey royal palace there is a radiant floor heating prototype, 80 BC, the famous Roman bathroom radiant floor heating in the form of "Tierra" Northeast China used since the kang is also applied the principle of radiant floor heating  stone coated metal roofing tile
The 1930s, Mr. Wright, the famous American architectural design master design works with a radiant floor heating, greatly promoted the application of floor heating, but the brass was only used as a heating coil, only expensive and corrosion leakage due to higher maintenance costs, resulting in radiant floor heating applications are a lot of restrictions.
Until the late 1960s, anti-aging, high temperature, high pressure, the pliable plastic pipe into the practical application, this situation has been changed before. Cheap, buried under ground interface, the inner wall of the tube is not easy to scale, the emergence of long life and other advantages of plastic pipe, greatly contributed to the promotion and application of the radiant floor heating technology.
Radiant floor heating compared to traditional heating unparalleled advantages, comfort, energy saving, environmental protection, etc., in a foreign country, the technology is not only used extensively for residential and various medical institutions, swimming pool, gym, shopping malls, office buildings and other public buildings also used extensively for the plant, hangar, flower beds, soccer fields and vegetable greenhouses and building systems such as thermal insulation, even for outdoor roads, roofs, stairs, airport runways snowmelt and various industrial pipeline insulation. Developed countries in Europe and the United States more than 50% of new buildings with a radiant floor heating system.
First, the most comfortable way of heating
Chinese medicine believes that "hot start from the students, from the foot into the cold. Modern Medicine also shows that the internal organs of the human body only under appropriate temperature conditions, in order to maintain the normal physiological function. When the cold outside, the function of the body automatically adjust, in order not to heat loss in the body, hands and feet blood will return in order to maintain the desired temperature of the internal organs. When the door temperature is low, the leg portions vasoconstriction, blood flow obstruction, resulting in systemic blood circulation is not smooth, so that the human body will feel chilly. So warm first warm feet, only the feet warm, the whole body will feel warm.
The traditional method of heating the top of the room about 30 ℃, and the location of the body in which the feet is only 15 ° C or even lower. Sit a long time will feel cold feet cold legs, cold legs and feet will increase the cold leg disease, the prevalence of arthritis may be.
Radiant floor heat is the most comfortable way of heating, even indoor surface temperature, room temperature from the bottom up, with the gradual decline of a high degree increase in temperature, this temperature curve fits the physical needs of the people, giving a head cold feet warm comfort . Floor heating can promote the occupants foot blood circulation, thus improving blood circulation, promote metabolism, and improve immunity to a certain extent. In addition, the "hot head cold environment to avoid drowsy, help enhance memory, improve learning and efficiency.
Second, efficient, energy-saving, low running costs
1, you can use more than hot water, solar, geothermal and other low temperature heat source;
2, radiant floor heating systems compared with the convection heating and high thermal efficiency, heat is concentrated at the height of human benefit, indoor set temperature even than convection heating side
Low-2 to 5 ° C, and also enables people to have the same warm feeling, so the temperature difference between the heat loss is greatly reduced;
3, the heat medium low temperature transfer, heat losses in the transmission process, the thermal efficiency is high;
4, as compared with other heating methods, the energy amplitude of approximately 20%, such as the use of the partition thermostat apparatus, the energy saving rate can reach 40%.
Third, environmental protection, health, health care
Radiant floor heating heating principle for radiation thermal conductivity compared by forced convection circulating hot air heating and air conditioning, heating, etc., dust in the air flow to small, to reduce the spread of harmful bacteria in the air, more hygienic cleaning of the indoor environment is conducive to bronchitis, respiratory infections and allergic syndrome health; air convection weakened, less water loss, to overcome the traditional radiator heating caused by indoor hot flashes, dry mouth discomfort, avoid women skin due to dehydration and excessive drying .
Fourth, do not account for the use of space, equal to spend the same money to buy a bigger house
Home life, we know that we can no longer Heating pipes furniture around, this is not only a considerable amount of use of the area is not applied to determine the overall decor, but also often a great deal of trouble.
Floor heating, the interior is no longer the radiator and its branch pipe, potentially increasing 2-3% of the indoor area not only for decoration and furniture arrangement is undoubtedly save you a few thousand dollars a square meter rates for major cities the cost of tens of thousands of dollars.
, Long life, maintenance-free, safe performance, saving maintenance costs
Buried in the floor of the floor heating coil, heating operation if not man-made destruction, almost does not exist the problem of maintenance, long service life of 50 years or more, non-corrosive, non-scaling, greatly reducing the radiator ran, run, drip, water leakage and maintenance of annoyance to the tenants, saving maintenance costs.
The initial Jian low cost, sub-control, measurement, easy to manage
Radiant floor heating compared with other single-family heating method does not increase construction costs and operation and maintenance costs, the room temperature according to the needs of independent regulation and control, convenient for household heat metering and charging.
To reduce the noise floor
At present, China's floor is generally used in prefabricated or cast-in-place plate, the very poor sound insulation, people walking upstairs, affecting the downstairs floor heating insulation, has a very good sound insulation to reduce noise pollution; underfloor heating silent process, the indoor environment is quiet, no air conditioning noise, which helps children to focus on learning, thus contributing to improve learning efficiency. stone coated metal roofing tile
8, long service life
Concrete floor heating, plastic pipes buried in the ground, such as one for the destruction of life in more than 50 years, non-corrosive, non-scaling, greatly reducing the radiator run, run, drip, water leakage and maintenance to households annoyance, saving maintenance costs.
