The Critical Role of Proper Temperature in Preventing Bacterial Growth in heaters

Filtered boiling water taps on and off the sink have changed offices permanently, providing instant access to boiling water for various purposes. However, beyond their convenience lies a critical aspect that significantly impacts safety: the storage temperature of the tap's heater.

Understanding the Danger

Water, particularly when stored inadequately, can become a breeding ground for harmful bacteria. Among these, Legionella pneumophila poses a significant threat. This bacterium can cause Legionnaires' disease, a severe form of pneumonia, when inhaled through contaminated water droplets.

The Ideal Storage Temperature

To prevent the growth and proliferation of dangerous bacteria like Legionella, maintaining the water in the heater at a temperature above 60 degrees Celsius (140 degrees Fahrenheit) is crucial. At this temperature or preferably higher, these harmful microorganisms cannot thrive or reproduce. Heaters from Hotspot Titanium store water at 99 degrees which makes it impossible for bacteria to grow.

Safety and Compliance

With some heaters, it is possible to set the storage temperature manually. Adhering to the recommended storage temperature not only ensures safety, but is also in line with regulations and guidelines established for water safety standards.

Impact on health and well-being

Buying a self-regulating system or maintaining the ideal storage temperature reduces the risk of water contamination and the possible spread of waterborne diseases. It protects users from the dangers of harmful bacteria and ensures their health and well-being.

Water Quality
Ensuring timely replacement of the water filter is crucial in maintaining the optimal performance and safety of boiling water taps. These filters play a vital role in purifying water, removing impurities, sediments, and potentially harmful contaminants. Therefore, maintaining a schedule for timely filter replacement is essential for both the functionality and safety of boiling water taps.

Filter replacement
The frequency of replacing a boiling water tap filter can vary based on usage and manufacturer recommendations. On average, a boiling water tap filter might require replacement every 6 months to 1 year or after approximately 1000 to 2000 litres of water usage and depending on water hardness. However, specific guidelines provided by the manufacturer for the particular model of the boiling water tap should be followed to ensure optimal performance and water quality.


In conclusion, the significance of the ideal storage temperature for water in a boiling water tap boiler cannot be overstated. To prevent the growth of dangerous bacteria like Legionella pneumophila and ensure water safety, maintaining the temperature above 60 degrees Celsius (140 degrees Fahrenheit) is imperative. Adherence to manufacturer guidelines and regulations is crucial to guaranteeing not only convenience but, more importantly, the safety and well-being of users. By upholding the correct storage temperature, users can enjoy the convenience of boiling water taps while safeguarding against potential health risks associated with contaminated water.

Remember, while the right heater temperature is crucial, regular maintenance, water filter change, and following manufacturer guidelines are equally essential for safe and optimal operation of boiling water tap systems.
