Common causes and solutions of floor heating without heat

As a new type of heating equipment, floor heating has been widely praised, but it also exposes some problems in operation. "Floor heating is not hot" is one of the most common problems in floor heating. Many people are helpless about this problem and can only seek the help of professional after-sales personnel. In fact, the floor heating structure is simple, and these are the reasons why it is not hot.

The main reason why geothermal energy is not hot.

Reason one: gas accumulation in the pipeline.

Just like heating, when the floor heating is filled with water, gas will be generated in the pipeline, and the phenomenon that the water inlet pipe of the floor heating is hot and return pipe is cold may occur. Every time before heating, the heating pipe system in residents' homes will not run for a long time, and there will be gas in it.

Solution: Open the air valve on the heater and let out the gas in the pipeline. After the hot water is circulated, the heater will heat up. In addition, some residents forget to open the outlet valve under the pipeline, so hot water cannot be circulated, so remember to open the outlet valve when starting heating.

Reason 2: The sundries in the pipeline were not cleaned up before use.

According to reports, when many maintenance workers go to residents' homes for exhaust debugging, they will find that the water flowing out of the heating pipe is black and contains many impurities. These impurities are all produced by fine sand or pipeline corrosion, and the accumulation of impurities in the pipeline will affect the hot water circulation of heating system.

Solution: Before the heating period begins, drain the water and wash away the sundries. And conduct a comprehensive cleaning of the floor heating pipeline every two years.

Reason 3: insufficient pressure in the floor heating circuit.

If the pressure in the floor heating loop is insufficient, it may lead to poor water circulation, hot water inlet pipe and cold return pipe.

The solution is to install a circulating pump to solve the problem of poor circulation (as the case may be).

Reason 4: For return pipe to take over.

When some users connect the heating pipes privately, the supply for return pipe is connected backwards, or when developers build houses, the supply for return pipe is connected backwards, which leads to "backward flow" of hot water and cold water, and the hot water circulation cannot be realized, resulting in the phenomenon that the heating is not hot. ?

Solution: Re-invite professionals to install heating facilities.

The above are the main reasons why the floor heating is not hot, and they all start from the floor heating pipeline system. In fact, in real life, the quality of wall-hung boiler also directly affects the heat dissipation efficiency of floor heating. Only by finding out the reason why the floor heating is not hot can we solve and maintain the problem. Here, Bian Xiao also reminds you that if you encounter problems that you can't solve, you'd better contact the staff of heating enterprises for on-site debugging and maintenance, so as to avoid the phenomenon of running water and affect your normal life.
