The reason why the warm water return pipe is not hot is not solved.

We know that in the northern part of the country, it is necessary to install floor heating in winter. In general, most people will still use the floor heating method for heating. However, we know that no matter what product is used for a long time, it will not return to the water pipe. . The following Xiao Bian will introduce to you the reason why the warm water return pipe is not hot, and the water return pipe is not a heat solution method.

1. Reasons why the floor return heating pipe is not hot : There is no exhaust pipe inside the heating pipe, and the return pipe valve is not open;

Generally speaking, as in the first operation of geothermal, it is easy to produce gas plugs due to pressure and water resistance in the pipeline, which is relatively easy to cause the supply and return water to not circulate, but it will lead to unequal temperatures, and exhaustion should be carried out by road. In general, there is a certain amount of gas in the pipeline where the steel column is filled with water, which may lead to “heating and entering the water. At this time, you can open the exhaust valve and directly exhaust it until you release hot water. .

2, lack of circulation power, water pressure.

Inlet and return pipes are also relatively prone to water pressure. At this time we must rely on water pressure to make the hot water circulate. If the water pressure is insufficient, the return pipe cannot flow into the hot water, so that the phenomenon that the heating water return pipe is not hot may easily occur.

3, the slope of the backwater pipeline is not enough.

If the pressure of the floor heating loop is insufficient, this will also lead to poor water circulation and a cold water inlet pipe will occur.

The solution: At this time you can go to the property or find a heating department. Circulating pumps can be added to solve the problem of poor circulation (as the case may be).

4, cold circuit in the pipeline / load is not average, so that way that is either hot or short circuit, or less heating, hot water directly approached.

The solution is to exhaust and measure the water pressure first, and then you can consider using the water return valve on this road.

5, warm water return pipe reason is not hot: the return pipe is blocked

After the heater has been used for a long time, the backwater pipe is blocked. This time is generally to clean the filter, the filter is mainly responsible for filtering the impurities in the floor heating system, if the filter blockage, it is prone to warm and hot.

6, uneven heating and cooling

At the same time, there were also some friends who responded to the heat of the house after installing the floor heating. Some rooms were neither hot nor hot or cold. More than half of this was due to unreasonable design or inappropriate construction.

The solution, this time is to find an experienced technician to solve this problem by modifying and adjusting the floor heating loop.

Summary: Regarding the reason why the warm water return pipe is not hot and the solution to the non-heat of the return pipe, the related contents are introduced. First of all, you must find out the reason before processing, so that you can solve it using the appropriate method. . In general, these are the reasons why the warm water return pipe is not hot. I hope the above introduction will help you.
