1, indoor heating is hot, but the room temperature can't meet the heating requirements.
This situation generally has the following reasons:
The heating temperature is low. The heating temperature of indoor heating hot water will change with the hot and cold weather, and the water supply temperature will increase when the outdoor temperature is low, but sometimes the outlet temperature of heat exchange station or heating boiler does not increase with the decrease of weather temperature, and the water supply temperature is low, which leads to the room temperature not meeting the requirements.
Home decoration is serious, the radiator covers a large area, and the heat can't be emitted. The design load of indoor heating system refers to the calculation of indoor bare heat dissipation. If the interior decoration is serious or covered by curtains, it will affect the heat dissipation, and then affect the indoor temperature. Therefore, in home decoration, try to install less radiators.
2. The geothermal design is unreasonable and there are few loops.
The construction is not standardized, and the length of each loop is different. Geothermal construction leads to blockage of individual circuits. It is necessary to redesign the building and install geothermal energy reasonably. Step by step to find the blocking point.
3. The indoor heating part is not hot
This situation generally has the following reasons:
Gas accumulation. There is gas accumulation in the radiator or at the end of the pipe. If there is gas accumulation in the radiator, the manual running air at the end of the radiator can be unscrewed and deflated. If there is gas accumulation at the end of the pipeline, you can also open the bleeder valve at the end of the pipeline to bleed.
Hydraulic imbalance. This kind of situation mostly happens in one household and one cycle installation system. Some radiators are not hot, but they can be turned off and reheated when they are hot. This phenomenon is called hydraulic imbalance of indoor circulation system. To deal with this situation, we can adjust the indoor system, first turn off the hot heater, let the lukewarm heater heat up, and then slowly turn on the hot heater. Note: When turning on the hot heaters, do not turn on all the hot heaters. The degree of opening must be moderate, so that the original hot heater can also be hot, and it is best to heat the unheated heater.
Blocking or unreasonable installation, unauthorized modification: if the above methods cannot be solved, the radiator or pipeline may be blocked or installed seriously unreasonable, and the unauthorized modification shall be given a warning and changed back to the original installation form within a time limit. If there is blockage or unreasonable installation, please ask professional maintenance personnel to disassemble and check, and eliminate the blockage or reinstall the pipeline through reasonable installation.
After the system has been used for a long time, the pipeline is seriously corroded and the pipe diameter becomes smaller. The original design does not meet the current heating requirements, and it is also prone to local overheating. In this case, the pipeline can only be redesigned and installed.
4, radiator installation quantity is not enough.
In order to save costs, some builders do not install radiators in the small living room and bathroom, which leads to the user's home not being hot. Users are advised to install radiators.
This room is not well sealed.
The doors and windows of some users' houses are not tightly sealed, which leads to poor room insulation effect, and the radiator is hot and the room temperature is not high. Users are advised to take corresponding measures to strengthen the airtightness of the room.
6, heating facilities used for too long.
Failure of users to maintain on time will cause internal corrosion, scaling and serious blockage, which will affect the heat dissipation effect and service life. Therefore, users should ask professionals to clean or replace the heating facilities in time before operation.
7, a wide range of thermal stop
First, ask the unit or district heating station whether there is power failure or water cut, whether the heat source or heating station equipment is faulty, and whether the main heating network is faulty, and then carry out maintenance and solution according to the corresponding situation.
8. Stop heating in a small area
Ask the neighbors if the situation is the same first. Secondly, find out the reason, determine whether the user's indoor heating facilities are faulty or the heating courtyard pipe network is faulty, and then find professional technicians to repair it.
9. None of the residents' valves are turned on.
Household heating valves in residents' homes, or heating valves in residents' homes are not opened after the heat metering reform, which will lead to hot water not entering the home. Open indoor household valves located in public corridors or residents' homes. If it cannot be solved, contact professional maintenance personnel or communicate with the heating company.
10, heating pipes or floor heating filters in residents' homes are blocked.
Due to many possible reasons, such as the aging and serious corrosion of the residential pipe network or the construction of the construction unit, there are foreign objects in the branch pipes of residents' homes, which block the heating pipes or floor heating filters, and the heating water circulation is not smooth, which leads to the reduction of heating effect in residents' homes. Hot users can contact professional maintenance personnel if they want to clear or replace blocked heating pipes or clean the filter screen in their rooms.
1 1. Neighbors installed drain valves and circulating pumps.
Some hot users install circulating pumps at home privately, or drain valves that put hot water privately, which will also lead to your home not being hot. The drain valve will release the hot water in the heating pipe, and the circulating pump will pump the hot water out of the heating pipe and concentrate it in the circulating pump, resulting in no hot water in the neighboring house. If you find that a drain valve and a circulating pump are installed in your neighbor's house, you can communicate with your neighbor or report the situation to the heating company in time.
12, the first floor of single-family heating is not hot.
During the operation of the system, some impurities accumulated at the end of the riser and could not be discharged, resulting in poor water flow and small water supply flow. Just open the drain valve at the end to discharge the blocked impurities.
13, single-family heating unit is not hot.
Because of the gas resistance formed by the gas accumulated in the riser on the roof, the hot water does not circulate, which can be eliminated by emptying the exhaust valve on the roof.
14, single-family heating, single-family heating.
Check whether the household valve is open first. If it is not a valve, it may be that the pipeline at the inlet end is blocked or the installation slope is unreasonable, resulting in air resistance. Exhaust the exhaust valve at the end of the user radiator to make the pipeline circulate smoothly; If it is not hot, it may be that the pipeline is blocked, so the system should be disassembled for inspection and the blocked sundries should be removed.
15, add and modify radiators by yourself.
The installation of radiator has strict technical requirements, so it must be installed under the window, so that the rising hot air flow can prevent and directly heat the cold air flow penetrating from the window gap, and the air flowing through the room is warmer and more comfortable. Users install and modify radiators by themselves, because the installation is not standardized, the location is unreasonable and there are many bends, which leads to the blockage of heating air and excessive water flow resistance, which not only makes their own heating not hot, but also affects all the heating connected to the same pipeline upstairs and downstairs. After the heating is over, we must find professional and technical personnel to carry out the transformation.
16, refitting the heating bleeder valve into a faucet.
The hot water in the pipe network contains chemicals to maintain the heating pipeline. Bathing and washing clothes with hot water from the heating pipe network not only affects the pressure of the heating pipe network, but also affects people's health. In order to ensure the pressure and personal health of the heating network, users are requested not to convert the vent valve of the heating package into a faucet.
17, poor radiator quality affects the heat dissipation effect.
Early central heating users installed old-fashioned steel strings at home, and some users bought radiators in pursuit of beauty, ignoring the practicality of radiators. Because these radiators are unevenly heated and have poor thermal conductivity, they are easy to cause blockage and the heating effect is very bad. It is recommended to find a professional technician to replace the radiator with good thermal conductivity.
