How to put water in when the floor heating is not hot?
The floor heating system is an important equipment for home heating in winter, but sometimes the heating is not hot. One of the common reasons is that there is air or impurities in the pipes that are blocked, resulting in poor circulation of hot water. This article will introduce in detail the method of draining water when the floor heating is not hot, and provide structured data to help you solve the problem quickly.
1. Analysis of the reasons why the floor heating is not hot
Underfloor heating may be caused by many reasons. The following are common causes and solutions:
| Reason | Solution |
|---|---|
| There is air in the pipe | Exhaust air by draining water |
| clogged pipes | Clean pipes or replace filters |
| Insufficient water pressure | Check the water replenishment valve and refill the water pressure |
| Thermostat failure | Check or replace thermostat |
2. Specific steps for draining floor heating
If the floor heating is not hot because there is air in the pipes, you can drain the water and exhaust it through the following steps:
1.Turn off floor heating system: First, turn off the power supply or gas valve of the floor heating to ensure that the system is in a stopped state.
2.Preparation tools:Gather a hose, a bucket or basin, and a wrench.
3.Find the drain valve: There is usually a drain valve on the floor heating water distributor, which is located on the side or bottom of the water distributor.
4.Connecting hose: Connect one end of the hose to the drain valve and put the other end into the bucket to prevent water from flowing to the ground.
5.Open the drain valve: Use a wrench to slowly open the drain valve to allow water and air to drain out together. Observe whether the water flow becomes clear and there are no bubbles.
6.Close the drain valve: After the water drain is completed, close the drain valve and check whether there is any water leakage in the system.
7.Restart floor heating system: Turn on the power or gas valve and observe whether the floor heating returns to normal operation.
3. Precautions
1.Water release frequency: Floor heating systems usually need to drain water 1-2 times a year to ensure that there is no air and impurities in the pipes.
2.Water pressure check: After draining the water, check whether the system water pressure is within the normal range (usually 1-2 bar).
3.Avoid frequent operations: Be gentle when draining water to avoid damaging the valve by using excessive force.
4.Professional help: If the problem is not solved after self-operation, it is recommended to contact professional maintenance personnel.
4. Frequently Asked Questions
| question | Answer |
|---|---|
| The floor heating is still not hot after the water is turned on | It may be that the pipe is blocked or the thermostat is faulty, further inspection is required. |
| The water flow is very small when water is released | The filter may be clogged and needs to be cleaned or replaced. |
| Water pressure drops after draining water | It is necessary to replenish the water pressure to the normal range through the water replenishing valve. |
5. Summary
When the floor heating is not hot, draining the water to exhaust is a common solution. You can do it easily with the steps and notes provided in this article. If the problem is complex, it is recommended to seek professional help to ensure the system is functioning properly. Regular maintenance of the floor heating system can effectively extend its service life and improve the heating effect.
