一. Precautions for users in the initial stage of heating
1. Pay attention to whether the heating facilities in your home are leaking, especially for some pipe joints, closely observe whether there are leaks, drips, or seepage phenomena, and repair them in time.　
2. Do not pile up debris on and around the radiator, and keep a good heat dissipation space for the radiator.
3. Do not pack the radiator too tightly to avoid poor heat dissipation.
4. Do not discharge or use hot water in heating facilities at will.　　
5. The various valves on the heating pipeline that have been debugged cannot be closed and opened at will.　
二. Common faults and solutions
Fault 1: Local "gas accumulation" in the radiator 　　
The phenomenon that the first few pieces of the radiator are hot and the latter few pieces are not hot may be caused by the local "gas accumulation" of the radiator.
Treatment method: loosen the deflation needle on the upper end of one side of the radiator a few threads, and stop the operation when the sound of gas is released, and tighten the deflation needle after the water flows out. Generally, you need to repeat the operation several times, and the heating will heat up. If the radiator is still not hot after exhausting the air, please ask the professionals of the heating company to find out the reason, and do not use the venting device to blindly drain the water.
Fault 2: Foreign matter on the radiator is blocked
If the upper part of the radiator is hot and the lower part is cold, it may be blocked by a foreign body.　
Treatment method: ask professional maintenance personnel to rinse.
Fault 3: The radiator bursts and leaks.
Treatment method: immediately block it with thick towels, rags and other items to reduce the water flow and reduce the loss caused by hot water gushing. The user of the household control system should close the water inlet and outlet valves of the radiator or the door valve; after taking emergency measures, please ask professionals for maintenance.
Fault 4: The surface temperature of the radiator is high, and the indoor temperature is low　　
This situation may be caused by the following reasons: poor insulation performance of the house, high heat consumption; excessive packaging of the radiator in house decoration, too small heat dissipation holes, and poor heat dissipation effect; there is a covering on the surface of the radiator, and the heat cannot be fully dissipated; After the user replaces the radiator, the number of slices is too small to meet the indoor heat dissipation load; the heat rate of a single building is too low, and many surrounding users do not use heat.
Treatment method: strengthen the heat preservation of the house; expand the radiating holes of the radiator decoration or remove the radiator decoration; do not place a cover on the surface of the radiator; choose the number of radiators according to the original design; increase the heat rate of the building.
Fault 5: The vent needle of the radiator is twisted or knocked off, causing water leakage 　　
Treatment method: immediately find a chopstick or thin wooden strip, sharpen one end, insert it into the fracture, stop the leak first, and then ask the maintenance staff of the heating company to repair it.
Trouble 6: After using the floor heating for a few years, the heating effect is getting worse and worse.
This situation may be due to the following reasons: long-term accumulation of water in the floor heating pipe, there are a large number of microorganisms in the water, and under suitable conditions, a large amount of biological slime will be produced, which adheres to the inner wall of the floor heating pipe and affects the performance of the floor heating pipe. The amount of water flow even causes partial blockage in the floor heating pipe, which leads to a decrease in the indoor temperature. According to relevant statistics, in the process of floor heating, every 1mm thickening of the scale on the inner wall of the floor heating pipe will cause the indoor temperature to drop by 6°C, which not only affects The normal temperature also causes a great waste of energy, and under a long-term high temperature, a large number of bacteria will be produced on the inner wall of the floor heating pipe, which will cause harm to the health of residents and the living environment.
Treatment method: ask professionals to clean and maintain the floor heating pipe every 2-3 years of use.
