At present, the ground radiant heating methods on the market include low-temperature hot water floor radiant heating system, heating cable floor radiant heating system, and electric heating film floor heating system, but the electric heating film floor heating system, due to the immature technology, has no national standard at present.
"Low-temperature hot water floor heating" uses hot water with a temperature not higher than 60 °C as the heat medium to be buried in the floor filling layer.
The hot water in the heating coil inside the electric floor heating flows, heating the floor, and supplying heat to the room through the ground by means of radiation and convection heat transfer, thereby achieving the purpose of heating;
The "heating cable floor radiant heating" system uses electric power as the energy source, the heating cable is the heating element, converts the electric energy into heat energy, and uses the indoor floor of the building as the heat dissipating surface, and supplies heat to the room through radiation and convection heat transfer through the ground. Heating method.

Electric heating in China's new heating method, from the indirect heating of electric heating film, geothermal cable to various direct electric heating heater products in the heating industry complement each other. The electric heating family can be easily divided into the following types:
Direct electric heating: wall-mounted and indoor electric heaters are direct electric heating products. Their heat is radiated by external materials or radiated by convection heat transfer. The indoor air is heated directly. The indoor temperature rises quickly and can be controlled quickly and easily. At room temperature, the direct heating electric heater cooperates with the temperature control device to form an electric heating heating system, which can meet the immediate needs of people.
Indirect electric heating: electric heating film, geothermal cable heating can be regarded as indirect electric heating mode, electric heating film and geothermal cable are hidden and installed in the ceiling and under the floor of the room respectively. The heat depends on the ceiling gypsum board and the floor material is slowly radiated after being heated, indirectly heating the room. The air is heated. The heating film of electric heating film and geothermal cable product conforms to the principle of floor heating and health care, and gives people the advantage of feeling comfortable and is used by high-grade residences.
Regenerative electric heaters; regenerative electric heaters are designed to use the peak-to-valley electricity price difference peak electricity to achieve the purpose of reducing electricity costs of electric heating equipment, the bottom of the valley for 8 hours using two times the heat load power electric heating tube to generate heat and heat The heat storage bricks use the heat stored in the heat storage bricks to support the heating throughout the day. In fact, the heat stored in the heat storage bricks can be continuously released without effective control, and the continuous effective heating can not be achieved for 16 hours. Heating increases power consumption. The maximum internal temperature of the electric heater can reach 900 °C, which affects the service life of the electric heating tube. The equipment has large power, large volume, large energy consumption, poor heat control performance, few behavioral energy saving space, high heating cost, and no peak and valley electricity price area. It is even more meaningless.

The warm core is a high-tech composite material, the name is - liquid thermosetting non-metal based electrothermal conversion material. The abbreviated NECMTM (Kemm) is magical in its “ultra-thin†and “energy-savingâ€. The warm core is thinner than paper, and its thickness is only 3 micrometers. It is different from traditional electric heating wire and plumbing. It can be folded and cut freely. It only transfers heat and is not conductive. It is hidden in the floor. After power-on, it quickly transfers heat through the wood. Passed to the human body.
The high-efficiency energy-saving of the warm core also has a leading edge, integrated in the floor, the electrothermal conversion rate is actually more than 95% (conventional cable \ electric heating film floor heating, electric heating conversion rate is only 55-60%).
Due to the high-tech characteristics of the warm core, it is integrated into the floor, which can be truly "maintenance-free", without aging, falling off, breaking, etc., and has a long life. As long as the floor is not bad, the warm core will not It will be bad. Warm core technology has subverted the old practice of traditional heating, creating a new era of high-tech heating, which has attracted the attention of relevant experts in the United States, Japan, South Korea and some countries in Northern Europe.
The “warm core†layer is a non-metallic inorganic material. It is not aging, does not fall off, has no wrinkles, is harmless to the human body, and has a long life of 50 years. The high-quality wood cooperates with domestic and foreign high-quality raw material suppliers, and the A-grade plate is fine. Choose to fundamentally guarantee product quality.
