Maintaining the correct temperature of tap water is essential for several reasons:

Microbial Growth: Water temperatures that deviate from the optimal range of around 5 degrees Celsius can promote the growth of harmful microorganisms such as bacteria and viruses. This poses a risk to public health and can lead to waterborne illnesses.

Chemical Reactions: Extreme temperatures, whether too hot or too cold, can alter the chemical composition of water and compromise its safety and taste. Proper temperature control ensures that water remains safe for consumption and household use.

Plumbing Integrity: Fluctuations in water temperature can also affect the integrity of plumbing systems, potentially leading to leaks, corrosion, and other costly damage.
