What does floor heating suppression mean? What does the owner need to do to test the water?

Floor heating is a kind of heating that many northern families will choose to install, but many people still don't know much about it. Then let's take a look at the meaning of floor heating suppression, what the owner needs to do in floor heating suppression testing, and how normal floor heating suppression is.

What does floor heating mean?

Many people don't know much about floor heating suppression, so let's see what floor heating suppression means.

Floor heating suppression is an inspection procedure for installing floor heating, because it can hardly be changed after backfilling, and there is no way to change it. Therefore, after installation, it is necessary to carry out inhibition test to avoid trouble caused by failure to subsequent use. If the pressing pressure is unqualified, it shows that there are problems such as water leakage and poor installation in the floor heating system. At this time, professionals should do a good job of investigation and repair.

Before the floor heating suppression inspection, we must always pay attention to the notice posted on the bulletin board of the community, because the community property will inform the owner of the time of the floor heating suppression inspection before the floor heating suppression inspection, and at the same time, someone must be at home on the day of the floor heating suppression inspection, especially the owner who has replaced the floor heating device.

During the floor heating inspection, if there is water leakage, it is necessary to close the valve passing through the house and take it to the heating company immediately, so that the other party can arrange staff to come to the house for maintenance. The filter at the inlet valve position should be kept clean, and the owner of the place where the inlet valve needs to be cleaned can be a professional of the residential property or heating company.

What does the floor heating need to do to suppress the test water?

Many owners don't know what floor heating needs to do to suppress water testing, so let's talk about what floor heating needs to do to suppress water testing.

1. Before floor heating pressure test, safe and effective fixing and maintenance measures shall be taken for pressure test pipes and components.

2. The pressure measured during floor heating suppression is not less than the system static pressure plus 0.28MPa, but not less than 0.28MPa.

3. If the floor heating is installed in winter, attention should be paid to the insulation of the floor heating pipeline during the suppression test to prevent icing.

4. After stabilizing the voltage 1h, make up the pressure to the specified test pressure value, and the pressure drop is less than O.05MPa within 15min, without leakage.

How much is the floor heating pressure drop normal?

Many friends still don't know how normal the floor heating pressure drop is. Then the following small series will tell you how normal the floor heating pressure drop is.

1, there will be pressure drop in the early stage of floor heating suppression, and it is normal to suppress the pressure drop within three pressures, because we need to inject water into the pipeline when suppressing floor heating, and the air in the pipeline will lead to pressure drop. However, after the floor heating is stable 1 hour, everyone will raise the water pressure to the specified pressure value, and the pressure drop within 10 minute cannot exceed 0.03mpa before it is qualified.

2. After the floor heating is installed, the construction personnel will check whether the pipeline leaks by means of overpressure floor heating. Everyone should pay attention when suppressing floor heating. The pressure test should be 1.5 times of the working pressure, and the pressure should not be higher than 0.6mpa or lower than 0.3mpa. If the floor heating is suppressed for too long or the pressure value is too large, the pipeline will be damaged.

3. Before the floor heating pipeline is pressed, we need to block the joints and valves of the water pipes with plugs; If the floor heating pipe is not properly connected, the pressure will drop and the test will be inaccurate. In the process of pressing, everyone should pay attention to observe whether there is water seepage in the pipeline, and if there is water seepage in the pipeline, it should be repaired in time.

4. After the installation and acceptance of the floor heating pipeline, it is forbidden to punch holes in the ground in the subsequent decoration project, because punching holes in the ground may damage the floor heating pipeline. When laying the floor on the ground, try not to lay the keel; Because laying keel will affect the heat dissipation effect of floor heating, you can consider laying tiles, laminate flooring and other floor decoration materials on the ground.
