Advantages of electric floor heating
1. It fundamentally solves the land occupation of boiler house, coal ash stacking and pipe network construction, and can plan the land occupation of boiler house into commercial house, and can obtain considerable income.
2. The problem of environmental pollution has been fundamentally solved. There is no coal ash, smoke, combustion waste gas, bluer sky and greener grass in the community, and there will be no low-level emission and reflux pollution caused by household gas heating.
3. It has fundamentally solved the problem of difficult collection of heating fees, which is the most headache of the property department. Residents pay by means of power purchase, which makes management more convenient.
4. It fundamentally solves the problems of running, emitting, dripping, leakage, radiator frost crack and traditional horizontal and vertical imbalance caused by water heating in the past. There is no need to set up a special maintenance organization, saving a lot of human, material and financial resources.
5. It fundamentally solves the large, medium and small maintenance of the boiler room and the second investment, and the service life of the heating cable is the same as that of the building.
6. The construction of heating cable system is simple and does not intersect with civil engineering. The system can be carried out simultaneously with decoration.
7. The capital can be invested by stages. It is not necessary to invest too much at one time like building a boiler room to reduce the occupation of capital.
8. Create a modern home, reflect modern life, meet individual needs, sell more houses, sell faster, and earn more.
Disadvantages of electric floor heating
1. There is a problem of power capacity increase in large households. The power of electric heating is calculated according to the square. The larger the heating area, the greater the use power and the greater the household power load. For some large house types, especially those with a heating area of more than 100 square meters, in addition to other electrical appliances in the customer's home, the problem of capacity increase may be considered. Generally, this problem is more prominent in the old community. This problem is the main problem restricting electric heating.
2. At present, when the heating area is large, the initial cost of electric heating is higher than that of water, floor heating and radiator, but the overall investment of heating cable is less. It depends on what you think.
3. Electric floor heating, like water floor heating, is a concealed project. Once there is a problem, the maintenance is troublesome. Therefore, during the installation of general electric floor heating, multiple links in the whole installation need to be tested and accepted.
4. At present, the heating cable electric floor heating is relatively chaotic, which is not conducive to the choice of users and the normal development of the market.
5. High cost, unable to provide domestic water.
What if the ground is not hot?
There are many reasons why the floor heating is not hot, some of which are problems that will occur in the process of use, and the other part may be caused by early-stage or technical defects. The following analyzes several common situations of floor heating and puts forward solutions.
1. Loop unevenness
Phenomenon: other users in the same community have good heating effect, but their own effect is not good, and the ground heating construction circuit is uneven.
Solution: use the small valve on the water separator to mediate the circulation of each circuit so that it can circulate evenly and achieve the ideal heating effect.
2. Filter clogging
Phenomenon: the main water supply rod is not hot, which may be due to the dirty heating water quality, resulting in the blockage of the filter and the failure of its normal circulation.
Solution: open the filter with a loose end wrench, clean the filter screen inside, and install it again. You can also find professional personnel to clean it.
3. Insufficient pipeline pressure
Phenomenon: the floors of some businesses are too high or the heating of the community is not at the end, and the pipeline pressure is not enough, resulting in unsatisfactory heating,
Solution: in this case, it is necessary to find a heating company or a property to solve it. If it cannot be solved, it is recommended to install a circulating pump to improve the circulation of heating water to achieve the ideal heating effect.
4. Gas in pipeline
Phenomenon: the main bar of floor heating is hot, and the return bar is not hot. There is gas in the pipeline, resulting in that hot water cannot enter the circuit and cannot be circulated.
Solution: use the vent valve on the water separator to open the gas in the pipeline and vent until hot water is discharged.
5. Floor heating is not cleaned for a long time
Phenomenon: the floor heating equipment is not maintained in time and in place, resulting in the floor heating is not hot. In the floor heating system, the average annual pipe scaling is 1mm, and the 1mm thick scale can cause the water temperature to drop by 6 ℃. In addition, the floor heating system mainly adopts the specially designed pipeline loop structure, with complex shape and long pipeline. The change of water supply temperature will produce calcium and magnesium ion scale, and the central heating will also have sludge rust scale, bacteria and algae. If it is treated irregularly and attached to the inner wall of the pipeline for a long time, the temperature of the floor heating system will be reduced, failure will occur, and even the floor heating pipeline will be blocked.
Solution: Generally speaking, the floor heating pipes are cleaned every 3-5 years. The floor heating equipment needs to be cleaned before the floor heating every year. The floor heating cleaning should be completed by a professional floor heating cleaning company.
If there is a problem with the controller of electric floor heating and the product has no self temperature limiting function, it may be transformed into the problem of unable to control the temperature after the heating effect is poor. If there is a problem with the heat source, there may be a problem with the insulation or a short circuit in one piece. The above points will cause damage to the whole floor heating system and even the house. I believe these analyses can let electric floor heating users know what to do if the floor heating is not hot -- find a professional company to solve the problem as soon as possible.
