What causes inconsistency of water temperature?

If it has just been installed,

Adjust the "Cold/Hot Water Valve" under the mixer tap to regulate the mixed water flow, altering the ratio of hot and cold water to lower down the temperature.

If it has been in use for some time (more than 6 months)

If there haven't been any issues before but suddenly the water temperature fluctuates, there could be 4 possible reasons:

1. Excessive impurities in the water can cause blockages in the interior of the water heater or the outlet pipes.
2. The aging of internal parts in the water heater affects the heating efficiency.
3. The pipes are leaking.
4. The water pump is malfunctioning.
