While geothermal heating is gradually being recognized, the topic of it has received attention. Select the geothermal floor to pay attention to five indicators. There is no national standard for geothermal flooring. It can only draw lessons from the practices of foreign countries, mainly South Korea and Japan, and is implemented by all domestic flooring companies. Consumers choose floor heating or worry, mainly because they are afraid of problems such as cracking or bad heat conduction during the use of the floor. To do this, you must pay attention to the five indicators:
Self-strength floor Korea green water floor Big Europe floor
1. Density of base material and internal bond strength—The higher the internal bond strength, the better the ability of the floor to withstand geothermal temperature changes and the phenomenon of cracking will not occur. For geothermal characteristics and requirements, the geothermal floor substrate is relatively dense. Wood can guarantee long-term no cracking and deformation under high temperature;
2, water thickness expansion rate - - less than or equal to 2.5%, the smaller the water thickness expansion rate shows that the floor moisture-proof performance becomes better;
3, the amount of formaldehyde emission must be selected as low as possible, because the higher the temperature, the greater the release of formaldehyde, in the relatively closed room plus other items (such as Daxinban, etc.) release, indoor formaldehyde It may exceed the standard and cause harm to the human body.
4. Heat Transfer Coefficient—There are few brands on the market that can provide heat transfer coefficient. Consumers should pay attention when buying. For example, the thermal conductivity of Montblanc's geothermal special floor is recognized by the Korea Building Materials Laboratory Research Institute and KOLAS International Inspection Agency. The inspection report shows that at an average temperature of 24 degrees Celsius, the floor thermal conductivity is 0.118 W/MK. Heat conduction is achieved and heat is maintained for a longer period of time.
5, the installation process --- "three points of floor, seven points installation", laying geothermal floor requires special methods, so as to ensure the safety of the floor in repeated changes in temperature conditions.
Geothermal heating needs more environmental protection
While geothermal heating is gradually being recognized, the topic of environmental protection has attracted attention. Especially for electric heating and floor heating systems, how to have the best matching and running stability is crucial. This determines whether the room is durable and whether it saves as much energy as possible. At present, there are many suppliers of electric heating systems, but only Di Wei's floor heating system uses a dual-core circuit that forms a loop for the heating and heating lines. After the power is turned on, the outgoing and return currents cancel each other and do not generate electricity. Electromagnetic field. Diwei's double-core cable is tested by the world's highest environmental standards and its electromagnetic field strength is "zero." In a double-core residential building, although the initial construction cost is 30% higher than that of a single core, in the future, the energy saving can be increased by 50%, and the improvement of living comfort can be achieved. 100%.
