How to solve the problem of floor heating and large indoor low temperature space?

The pressure difference between the supply and return water of the heating company is small, and the water flow is reduced, which leads to the geothermal heat is not hot. This situation can be solved by looking for a property.

1, the geothermal pipe is not cleaned.

The first reason why geothermal energy is not hot is that the floor heating pipeline is not cleaned and scale accumulates. When the floor heating equipment is used for a long time, calcium and magnesium ions in the floor heating pipe will combine to form scale and impurities. And the thermal conductivity of scale is very poor. In the process of heat exchange, the scale will increase from 0mm to 0.3mm, and the heat exchange rate will drop to 79%. That is to say, when the scale thickness reaches 0.3mm, 2 1% heat will not be converted normally, resulting in geothermal energy.

Therefore, users are advised to clean the floor heating pipes in time, and it is best to carry out professional cleaning on the later floor heating pipes every two years, and the cleaning time can be before, during and after heating.

2. There is air in the geothermal pipeline.

If the main pole of floor heating is hot and the return pole is not hot, it may be that there is air in the floor heating pipeline, causing air resistance, resulting in hot water not entering the loop and not circulating.

In this case, we need to check whether the backwater valve is open (I-shaped means open, X-shaped means closed); If the air in the geothermal pipeline causes air resistance, open the air valve to exhaust until hot water is released, or use the small valve on the water separator to adjust the circulation of each loop to make it circulate evenly, so as to achieve the ideal heating effect.

3, the system cycle is poor

The pressure difference between the supply and return water of the heating company is small, and the water flow is reduced, which leads to the geothermal heat is not hot. This situation can be solved by looking for a property.

4. Neighborhood conflicts are too great.

Maybe your neighbor or upstairs and downstairs installed a circulating pump on the pipeline, which caused too much water to flow to his house, and people nearby would naturally be implicated. If the residents can't solve it themselves, they can negotiate with their neighbors and property.

5, the water temperature is low

In order to achieve the ideal indoor temperature 18~22 degrees Celsius, the floor heating water supply temperature must reach above 45 degrees Celsius. You can measure the temperature of the water inlet pipe yourself, or you can find a professional. If you can't meet the standard, you can contact the property in your respective community.

6, the effective heat dissipation area is small

Floor heating is radiant heating, and heat is radiated from bottom to top. More ground coverage will affect heat dissipation. For example, in the bedroom, if you put a large floor-to-ceiling bed and wardrobe, the effective heat dissipation area is only 30-40%, which is 50% less than that in the room with furniture and legs. Therefore, too much ground coverage will also affect the heat dissipation effect of floor heating, which makes people mistakenly think that it is not hot. In order to make the floor heating play a better heat dissipation effect, it is best to choose furniture with legs instead of laying carpets on a large area.

7. Improper construction

In the installation of floor heating, some constructors, in order to save the floor heating pipes, expand the coil spacing when heating the coils, or the floor laid above the pipes is too thick, which will affect the heat dissipation efficiency of floor heating. It is troublesome to deal with this phenomenon. It is necessary to re-lay the floor heating pipe or reduce the floor thickness, which is a waste of time and causes great economic losses. Therefore, it is recommended that users must find a professional and formal company for installation.
