How to add water to a wall-hung boiler: Detailed operating instructions and precautions
As a common heating equipment in modern homes, wall-mounted boilers are inseparable from proper water pressure for their normal operation. If the water pressure is insufficient, the heating effect may be reduced or even equipment failure may occur. This article will introduce in detail the steps, precautions and FAQs for adding water to the wall-mounted boiler to help you complete the operation easily.
1. Preparations before adding water to the wall-hung boiler
1.Check water pressure gauge: Confirm whether the current water pressure is lower than the normal range (usually 1-1.5bar).
2.power off: To avoid potential safety hazards, turn off the power supply of the wall-hung boiler before adding water.
3.Preparation tools: Make sure you have the appropriate key or handle for the refill valve (some models require special tools).
| water pressure status | Operation suggestions |
|---|---|
| Below 0.5bar | Need to replenish water immediately |
| 0.5-1bar | It is recommended to replenish water to 1.5bar |
| higher than 2bar | Need to relieve pressure |
2. Detailed explanation of the steps for adding water to the wall-hung boiler
1.Find the refill valve: Usually located at the bottom of the wall-mounted boiler, labeled as "Fill Valve" or "Fill Valve".
2.Open the valve slowly: Rotate 90 degrees counterclockwise and observe the pressure gauge after hearing the sound of water flow.
3.Monitor water pressure: When the pointer reaches 1.5bar, immediately close the valve (turn clockwise).
4.Restart the boiler: Check whether normal operation resumes after powering on.
| steps | key action | Things to note |
|---|---|---|
| 1 | Positioning water replenishment valve | Reference manual illustration |
| 2 | open valve | Be gentle to avoid damage |
| 3 | Observe the pressure gauge | It is strictly prohibited to exceed 2bar |
3. Dealing with common problems after adding water
Problem 1: The pressure continues to drop after adding water
Possible reasons: The pipeline is leaking or the pressure relief valve is faulty. You need to contact a professional for repair.
Problem 2: The water replenishment valve cannot be closed
Emergency treatment: Close the main water inlet valve and call after-sales service.
| Fault phenomenon | Possible reasons | solution |
|---|---|---|
| No change in pressure gauge | Water replenishment valve clogged | Clean or replace valve |
| Abnormal noise after adding water | There is air in the system | Perform exhaust operation |
4. Professional maintenance suggestions
1. Check the water pressure system once a year before the heating season.
2. When not in use for a long time, the water stored in the pipeline should be drained.
3. It is recommended that professionals perform comprehensive maintenance every 3 years.
Through the above structured guidance, you can complete the water filling operation of the wall-mounted boiler safely and efficiently. In case of complicated situations, please contact the brand’s after-sales service first to avoid equipment damage caused by self-disassembly.
