What is the main difference between geothermal and underfloor heating

There should be no big difference in this, the general floor heating equipment is the same, the main thing is to look at the manual installation and after-sales service. The equipment is basically the same, and nothing else.

Geothermal radiant heating, referred to as floor heating, is a heating method in which hot water or heating cables with a temperature of no higher than 60 degrees Celsius are buried in the coil system under the geothermal floor to heat the entire ground, and the heat is evenly radiated to the room through the ground. Compared with traditional heating methods, geothermal radiant heating has many characteristics such as comfort, energy saving and environmental protection. In foreign countries, this technology is not only widely used in civil residences and hospitals, shopping malls, office buildings, gyms and swimming pools and other public buildings, but also widely used in the insulation of building systems such as flower beds, factories, football fields, hangars and vegetable greenhouses, and even used in the insulation of outdoor roads, roofs, stairs, airport runways and various industrial pipelines.

At present, more than 50% of new buildings in developed countries such as South Korea, Japan, Europe and the United States have adopted geothermal radiant heating. Floor heating is also a new type of heating method that has begun to emerge in China in recent years in the north of the Yellow River, and its application has been quite wide in Shandong, Tianjin, Northeast, Inner Mongolia, Hebei and other places in China. In Tianjin, for example, floor heating already accounts for 40% of new buildings, which is widely welcomed by residents.

China** has listed floor heating as a key building energy-saving technology for the promotion and application. From the perspective of development prospects, more than 60% of the future residential heating will take floor heating, and the application prospects are gratifying, and there is a huge development market.

Compared with the ordinary heat dissipation heating method, the heating method of upward radiation heat heating through low-temperature hot water has many advantages: first, it meets the comfort requirements of human physiological heating: let the warmth start from the feet, people will feel warmer and more comfortable; The second is to save indoor area and space

It can save the space occupied by the installation of radiators and heating pipes, and increase the usable area by 2% 3%; Third, the indoor heating temperature can be uniform: after the use of floor heating, the room temperature is distributed from bottom to top, the air convection is weakened, and the water dispersion loss is reduced, which overcomes the shortcomings of radiator heating, such as dry mouth; Fourth, the choice of heat sources is relatively wide, and underground hot water, industrial waste heat, heating pipe network, household heating source, etc. can be used; Fifth, energy saving and money: compared with other heating methods, geothermal radiant heating is almost no convection up and down compared with Rayleigh number Ra<1, the air is almost no up and down convection, the room temperature is distributed from bottom to top, the ceiling temperature is the lowest, and the energy saving range is about 20%, and if the zonal temperature control device is used, the energy saving range can reach 40%; Sixth, increase the thickness of the ground

And aerated (foam) concrete has a good sound absorption effect, so it has a good floor sound insulation effect.

Floor heating is called ground radiant heating, floor heating is divided into water floor heating and electric floor heating, according to the current "JGJ142-2004 ground radiation heating technical regulations" division of water floor heating is to the temperature of hot water not higher than 60 as the heat medium, in the heating pipe embedded in the ground below the filling layer of the heating pipe circulation, heating the whole floor, through the ground to radiation and convection heat transfer mode to indoor heating mode; The electric floor heating is a heating cable that buries the upper limit of the allowable working temperature of 65 on the outer surface in the floor, heats the floor with the heating cable as the heat source, and controls the room temperature or floor temperature with a thermostat to realize the heating mode of ground radiant heating.

Floor heating is a kind of heating method in residential quarters, which is different from traditional indoor hanging radiators, and the heating pipes are buried under the indoor floor for heating. This heating method is more evenly dissipated than the previous way, the hot air is evenly distributed from the bottom up, the whole room is warm, and the floor has temperature, which ensures that people's legs and feet are warm, which is very good for the body.
