The low-temperature hot water floor heating technology heats the floor with a hot water coil embedded in the floor to uniformly radiate heat to the room to achieve heating. The heating cable low-temperature radiant heating system uses electric power as the energy source, and the heating cable is the heating element, which converts 100% of the electric energy into heat energy, and uses the ground inside the building as the heat radiating surface to heat the surrounding air by convection heat exchange. The floor heating system is composed of a heating cable and a thermostat. The heating cable is laid on the ground, and the thermostat is installed on the wall. When the indoor ambient temperature or the ground temperature is lower than the temperature set by the thermostat, the thermostat When the power is turned on, the heating cable starts to heat up after being energized, and the generated heat is absorbed by the covered cement layer, and then the indoor air is uniformly heated. Why is floor heating "most comfortable" in terms of comfort? Because the end method used is radiant heating, floor heating is generally considered to be the most comfortable heating method.
The traditional heating system and the floor heating, the heat is emitted from the height of the head, rising from the wall to the roof, forming a cycle of hot air in the room, the temperature distribution is chaotic, which will make people feel uncomfortable with the cold feet, and the floor Heating is the temperature of the air close to the ground first, then the entire room from the ground to the roof to form a reasonable air temperature field, so that the human foot, body and head have a comfortable temperature difference. The cost of the two methods is different. Regardless of the floor heating method, the people are most concerned about the cost of using the floor heating system in the future.
At present, in Beijing, the hydrothermal floor heating adopts the heating group central heating and the gas wall-hung boiler as the heat source. The former is 24 yuan/square meter for each heating season according to the current national charging standard, and the natural gas is burned through the gas wall-mounted furnace. Then charge according to the price of 1.9 yuan / cubic meter, in addition, it is estimated that the replacement cost of the gas stove every ten years is about 6000-7000 yuan, and the heating floor heating, continue to perform the same low price electricity price as last year, in During the heating period, from 23:00 every night to 7:00 the next day, it will be 0.2 yuan/kWh (including the Three Gorges Construction Fund and the city utility surcharge), and the electricity price will remain unchanged for the rest of the period. Here we only briefly introduce the unit price of the different ways of floor heating, because according to experts, the key to the real energy consumption and operating costs depends on the insulation performance of the building.
According to reports, if your house can guarantee a good warmth system, especially by warming some exterior walls, making the whole building like a large insulated barrel, the heat will not be easily lost. The degree of advantage of the heating system of residential products directly affects the quality of heating. In addition, the floor, orientation, floor plan of the house where you live, the location of the house in the building, the floor area has an effect on the floor heating effect.
