[How about geothermal film] Does geothermal film cost electricity? Installation method of geothermal film
Does geothermal film cost electricity?
Electric film heating adopts a concept of energy saving and environmental protection, and the utilization rate of electric energy is very high. 100% conversion saves 40% of electricity consumption compared with the traditional heating method, electric water heater circulating heating, but the thermal film has requirements for the construction method, and a suitable building is more conducive to the thermal film, which will save more electricity, and it is also related to the temperature. The relationship depends on the range of temperature control, such as 500 square meters, the temperature is about 20 degrees, the traditional way of electricity consumption per hour is 28.5 kilowatt-hours (degrees), 0.5 yuan per kilowatt-hour, that is 28.5*0.5=14.25 The electricity consumption per hour of the thermal film heating method is 17 degrees, 0.5 yuan per kilowatt-hour, which is 17*0.5=8.5 yuan per hour and saves 5.75 yuan per hour. If the temperature is controlled at about 25 degrees, then the traditional method consumes 5.75 yuan per hour. The electricity is about 38 degrees, 0.5 yuan per kWh, which is 38*0.5=19 yuan, and the thermal film heating method consumes 22.8 degrees of electricity for one hour, which is 22.8*0.5=11.4 yuan, which saves 7.6 yuan per hour.
Installation method of floor heating film
1. The assembled sub-catchment shall be firmly attached to the wall according to the position and elevation determined in advance according to the actual situation of the user’s home, and shall be fixed with expansion bolts. In order to prevent heat loss, it is necessary to put a special insulation jacket on the pipe from the sub-catchment to the installation room. Connect the insulated pipe to the sub-collector and connect one end of the pipe to its thermostatic valve. After the pipe is laid, put the end of the pipe on and pass it back to the sub-catchment to fix it. Before the floor heating is officially started, the indoor floor must be cleaned to ensure the level of the floor and remove the unevenness and sundries on the floor. Then, it is necessary to conduct a site visit to the entire home to determine the installation location of the wall-hung boiler and the sub-catchment.
2. The insulation board should be laid flat, cut neatly, and the joints should be tight. The whole board should be placed around, and the cutting board should be placed in the middle. When laying, pay attention to the flatness of the insulation board and the height difference. It is allowed to exceed plus or minus 5MM, and the gap is not more than 5MM. The reflective film must be laid flat and must not be wrinkled. Cover tightly, there should be no leakage of insulation board or ground phenomenon. The squares of the reflective film should be symmetrical and neat, and there should be no misalignment. The reflective films must be pasted with transparent tape or aluminum foil tape. High-quality reflective film and standardized laying can reflect 99% of the heat.
3. After the geothermal film is laid, it should be tested by hydraulic pressure. First, the pipeline should be flushed with water pressure, purged, etc., to ensure that there is no foreign matter in the pipeline. Then inject clean water from the water injection and exhaust valve, the test pressure is 1.5 to 2 times the working pressure, but not less than 0.6Mpa, the pressure drop within 1 hour of pressure stabilization is not more than 0.05Mpa, and no leakage or leakage is qualified. When backfilling the fine stone concrete, all manual plastering and compaction are used to keep the horizontal line of the whole house at a height, and the wire mesh shall not be exposed. When laying concrete, marks must be made at the door, aisle, floor drain, etc. to prevent improper behavior in the later construction from damaging the geothermal membrane.
