How to solve the problem of hot water entering and cold water exiting in floor heating

1, there is air in the floor heating pipe:

Because there is air in the floor heating, which hinders the backwater circulation of the floor heating, there is an exhaust valve on the floor heating water separator, which is mainly used to exhaust the air in the floor heating pipeline. The newly installed floor heating must be exhausted before use.

Specific operation method:

For example, there are five loops in the floor heating at home, so first close four loops, open the backwater exhaust valve, and discharge one of them until only water comes out of the pipeline without exhaust, and then close the valve, and all loops will operate according to this method.

2, the water temperature is too low:

If we want to ensure that our indoor temperature reaches 18-22 degrees Celsius in winter, the water temperature in the floor heating pipeline should be around 45 degrees Celsius. If heating is used, the water temperature should reach 60 degrees. We'd better find a professional to conduct some temperature tests on the water in the floor heating pipeline. If the temperature is not up to standard, you can contact our residential property to solve it.

3, poor circulation system:

If the pressure difference between the supply and return water of the heating company is small, the circulating force of the water flow will be reduced, and the velocity of the water flow will be reduced, which will also lead to the situation that the floor is warm and not hot. If it is because of this problem, it is best to contact the property management to solve it.

4. Excessive competition:

If a neighbor of the unit building where he lives has installed a circulating pump, more water in the floor heating pipe will flow to his home, and the nearby neighbor's home will be implicated. If this is the case, it is best to talk to the property management. This is not authentic, and there is no need to install a circulating pump.

5. The filter screen is blocked:

In fact, there is a filter screen on the indoor water separator, whose main function is to filter impurities in the water. If there are too many impurities in the water in the floor heating pipe, the filter screen will also be seriously blocked, resulting in a decrease in the speed of water. If there is no water flow in the floor heating pipe, the indoor temperature will definitely be affected. In this case, you need to clean the filter.

6. There is dirt on the inner wall of the floor heating pipe:

According to scientific calculation, the scale and clay with the thickness of 1- 1.5 mm deposited on the inner wall of the floor heating pipe will hinder heat dissipation, which will reduce the indoor temperature by 3-6 degrees, which is even more serious in some areas with poor water quality, and the thermal conductivity of scale is also extremely poor. In the process of reheating, the scale will increase from 0 mm to 0.3 mm, which means the heat exchange rate will decrease to 79%. There will be 2 1% heat that cannot be converted normally. If this happens, our best way is to find professionals to clean the floor heating pipes.

7, pipeline cement layer is too thick:

If we don't pay special attention to the construction, the thickness of the cement layer on the floor heating pipe is too thick, which will also make it difficult to release the temperature in the floor heating pipe to our room. In fact, this situation is relatively easy to solve, which is nothing more than finding a professional geothermal company to install when laying the floor heating pipeline.
