Understanding Your Wall-Mounted Boiler: Why Shower Water Isn't Heating

After installing a wall-mounted boiler at home, using hot water for showers becomes particularly convenient. However, if the boiler has no issues with its other functions but the water is not very hot during showering, what could be the reasons for this, and how can it be resolved?

Reasons for Inadequate Hot Water Supply from the Wall-Mounted Boiler

1. Low gas pressure in the home can lead to insufficient heating of the water.

2. If the supply pipes for the water are installed too long, any faults along the way can affect the heating efficiency.

3. A small diameter in the boiler's intake pipe may result in poor water circulation, causing the water to not heat properly.

4. The boiler has a controller that directly manages heat provision. A fault in this controller could lead to a lack of hot water.

5. The presence of scale and other impurities in the boiler's pipes can obstruct water circulation, preventing effective heat supply and resulting in lukewarm water.

How to Resolve the Issue of Inadequate Hot Water Supply from the Wall-Mounted Boiler

1. If unstable water pressure is the cause, check whether the boiler's water refill valve is properly tightened. If not, and if the household is located on a higher floor with lower water pressure, this may lead to hot water issues. Installing a booster pump can help resolve the problem.

2. Ensure that the temperature settings on the wall-mounted boiler are appropriate; exceeding the preset temperature could lead the boiler to cease heating. A recommended setting is around 45 degrees Celsius for optimal results.

3. If there is a significant buildup of scale inside the boiler, it may hinder hot water supply. Timely removal of impurities from the pipes is advisable, and professional assistance may be needed for cleaning.

In conclusion：if you find that the water for your showers is not sufficiently hot, it is crucial to identify the underlying reasons and address them accordingly.
