How to fill the gas wall-hung boiler with water
The gas wall-mounted boiler is one of the important equipments for modern home heating. Correct water supply is a key step to ensure its normal operation. This article will introduce in detail the specific method of filling the gas wall-mounted boiler with water, and combine it with the hot topics and hot content on the entire network in the past 10 days to help users better understand and operate.
1. Steps to fill the gas wall-hung boiler with water
1.Check system pressure: First check the value of the wall-mounted boiler pressure gauge, usually the normal range is 1-1.5bar. If the pressure is lower than 0.5bar, water replenishment is required.
2.power off: To ensure safety, the power supply to the wall-mounted boiler must be turned off before filling the water.
3.Open the water replenishment valve: Find the water replenishment valve (usually a blue knob) under the wall-hung boiler, turn it slowly counterclockwise, and stop when you hear the sound of water flowing.
4.Observe the pressure gauge: During the water replenishment process, you need to continuously observe the pressure gauge. When the pressure reaches 1-1.5bar, immediately close the water replenishment valve clockwise.
5.Exhaust treatment: If there is air in the system, open the exhaust valve of the radiator to discharge the air until the water flow is stable.
6.Restart the boiler: After filling the water, restart the wall-hung boiler and check whether it is operating normally.
2. Precautions
1. Do not exceed the maximum pressure value (usually 2bar) when replenishing water, otherwise the safety valve may be triggered to release pressure.
2. If you need to replenish water frequently, there may be a water leakage problem in the system, and you need to contact a professional for repair.
3. When filling water in winter, pay attention to anti-freeze to avoid freezing of pipes.
