1. What is the reason why the radiator is not too hot when the heat source is normal?
Continuous cooling in many places, the radiator has become the best choice for most users. The advantages of the radiator are: the heating of the radiator is relatively fast, and it can be used immediately; the cost of the radiator is relatively much lower than that of other heating methods; there is no requirement for the ground material; the radiator is generally installed on the wall and other places, and its Maintenance is relatively convenient, such as floor heating.
At the same time, in the heating season, many HVAC practitioners often receive complaints from end users: “The wall-hung boiler at home is working normally, but the radiator is not very hot, it feels cold, you heating Is there something wrong with the quality of the film?” After investigation and analysis, it is found that many users have this situation because the boiler temperature rises very fast, and soon reaches the protection temperature and shuts down. After a period of time, the combustion is still the same, so the boiler It does not work continuously, but works intermittently. In fact, this is a fault, and the boiler is not burning normally.
2. Reasons and solutions for heating boilers to heat up quickly
1. Blockage
Heating A large amount of air in the system is not exhausted, causing air blockage or partial blockage of the heating system, so that the water circulation speed is slow, resulting in the failure.
Solution: As the name suggests, exhaust or check for blockages.
2. The opening of the sub-catchment or valve is too small
Many times we tend to ignore the opening of the sub-catchment. Too small can also cause this failure.
Solution: If you choose the octopus connection, you can check the opening of the manifold or valve.
3. The power of the water pump does not match
Sometimes the power of the water pump cannot meet the resistance of the heating system. On the one hand, it may be that the water pump of the wall-hung boiler is too small. On the one hand, it may be that the pump gear is not suitable.
Solution: At this time, it is necessary to recalculate the system resistance, and select the appropriate pump gear, or add an external pump.
4. Bypass valve failure
When the radiator wall-hung boiler is used for a long time, the bypass valve installed between the water supply and return pipes inside the boiler There may be a phenomenon that cannot be reset normally, which may easily cause a small circulation state inside the boiler.
Solution: Therefore, when the above troubleshooting still cannot solve the problem, it is necessary to consider whether the bypass valve is faulty.
