How is it that a single heater is not hot?

The reasons why the single heater is not hot are: there is gas in the pipe, the pipe is blocked, the filter screen is blocked, the water pressure is not enough, and the water temperature is not enough.

1, there is gas in the pipe.

The heating pipe is so thick that it should have been filled with water. Now entering the air, the hot water content naturally decreases. And hot water is the main heating tool for water heating. Without water, the heating temperature will not be high.

How did the air in the pipe come in? During the non-heating period, there is no water in the heating pipe, but all air. As soon as the heating period arrives, the heating water will slowly fill the pipeline-note that the water flows into the pipeline slowly, not instantaneously. In this way, it is possible to squeeze out the gas in the pipeline and cannot be discharged.

2. The pipeline is blocked

Just like the gas in the pipeline, if the inside of the pipeline is blocked by various magazines such as rust, scale and sediment, the hot water content will definitely decrease. The probability of heating pipe blockage is much greater than that of tap water pipe. On the one hand, the water quality of heating water itself is not good; On the other hand, because the heating pipe is vacant during the non-heating period, it is very easy to rust or fall into dirty things.

3. The filter screen is blocked

Heating generally has a filter screen, but this filter screen can't stop the magazines such as scale and rust mentioned above, and can only stop some large sediments. Therefore, the probability that the filter screen is blocked is relatively small. Generally, it is a newly-built heating pipe or a newly-built heating pipe, which is easy to block the filter.

The filter screen is blocked, so the heating water cannot enter the room smoothly, and the heating temperature is naturally not enough. We can open the filter screen for cleaning: the filter screen of floor heating is generally in the position of the water separator.

4, the water pressure is not enough

The more heating pipes in the home, the higher the requirement for water pressure. If the water pressure is insufficient, air can easily enter the pipeline, and the water flow speed is very slow, resulting in the water temperature not meeting the corresponding requirements.

Users who heat themselves can install a high-power booster pump in the pipeline. For users of central heating, the reason of insufficient water pressure may be that the heating company did not provide qualified pressure, or it may be caused by installing too many heating pipes during decoration.

5. Insufficient water temperature

Having said so many questions about water and pipes, the last one is the most critical-if the water temperature is not enough, the pipes are full of cold water and the heating is not hot.

Generally speaking, radiators require much higher water temperature than floor heating. For example, to reach 20℃ indoors, floor heating may only need 45℃ water temperature, while radiator needs 60℃.

solution

1. Check whether the external network of the whole heating system is not insulated or the insulation fails. What we can do at this time is to re-insulate the whole pipe network system to ensure that the insulation can be qualified.

2. Check the leakage of outdoor pipe network. For example, you can go to the heating station or boiler room to see if the pressure drops quickly and whether the water supply in the boiler room far exceeds the normal water supply. At this time, we should look for the leakage point according to the direction of the pipe network.

3. Check the circulation of the hot inlet device for our heating. Generally, the main inspection is the circulation valve. At the same time, it depends on the installation of pressure gauge, thermometer, drain valve and bypass valve of hot inlet device.
