Why is the water in the wall-mounted boiler not hot?

Recently, many users have encountered the problem of not getting hot water when using wall-mounted boilers in winter, which has become one of the hot topics on the Internet. Wall-mounted boilers are important equipment for home heating and hot water supply. Once they malfunction, they will directly affect the quality of life. This article will combine the popular discussions and expert suggestions on the Internet in the past 10 days to provide you with a detailed analysis of the reasons and solutions for the wall-mounted boiler water not being hot.

1. Common reasons why the water in wall-hung boilers is not hot

2. Detailed solutions

1. Check water pressure

The water pressure for normal operation of the wall-hung boiler should be between 1-2 bar. If the water pressure is too low, water can be replenished through the water replenishment valve; if the water pressure is too high, water can be released through the drain valve. After replenishing water, make sure to close the replenishing valve to avoid continued pressure rise.

2. Check gas supply

Make sure the gas valve is fully open and check whether the balance on the gas meter is sufficient. If liquefied gas is used, check whether the cylinder valve and pressure reducing valve are working properly. Recently, gas supply shortages have occurred in many places. It is recommended to contact the gas company to confirm the gas supply pressure.

3. Clean the heat exchanger

A clogged heat exchanger is a common cause of lukewarm water. It is recommended to have it professionally cleaned every 2-3 years. If there is obvious scale or carbon deposits on the surface of the heat exchanger, it needs to be dealt with immediately.

4. Check temperature settings

Make sure the temperature of the wall-mounted boiler is set in the appropriate range: domestic hot water is recommended to be 50-60°C, and heating water temperature is recommended to be 60-70°C. Some users report that even when the temperature is set to the highest setting, it still doesn't get hot, which often indicates another fault.

3. Recent user feedback on high-frequency issues

4. Preventive maintenance suggestions

1. Ask professionals to conduct a comprehensive inspection before the heating season every year

2. Clean the water inlet filter regularly (recommended once a month)

3. Keep the area around the boiler well ventilated

4. When not in use for a long time, the system should be drained of water.

5. Using a water softener can extend the life of your equipment

5. When does it require professional maintenance?

If the problem is not solved after trying the above methods, or if the following situations occur, please contact professional maintenance personnel immediately:

- The wall-mounted boiler displays a fault code

- Smell a gas leak

- The device makes unusual noises

- Frequent automatic flameout

According to maintenance data statistics from the entire network, about 65% of wall-hung boiler non-heating problems can be solved by users themselves, while the remaining 35% require professional handling. It is recommended to try simple troubleshooting first, and then seek professional help if it doesn't work.

Through the above analysis, I hope it can help you quickly find the reason why the water in the wall-mounted boiler is not hot and solve the problem. Heating in winter is important for the comfort of the whole family. If problems arise, they can be dealt with promptly so that they can survive the winter warmly.
