The answer to this goes far beyond personal preferences and health and technology concerns.
Warm does not automatically mean better
The hot water from the tap has already been on a journey—usually through the boiler or heating system. Heavy metals such as copper or lead can enter the water in older systems.
These impurities pose a health risk that cold water usually does not. Cold water comes directly from the mains and is often fresher and cleaner. This choice will definitely affect the taste of tea or coffee.
Limescale, the enemy of the kettle
Hot water often contains more dissolved minerals, such as lime. This may be good for your bones but bad for your kettle. Limescale deposits build up more quickly and impair the appliance’s efficiency.
The result is higher energy consumption and more effort for cleaning. With cold water, you can extend the life of your kettle and save yourself a trip to the descaler.
Efficient and clever heating
Many people assume that hot water from the tap saves time and energy. But this is a fallacy. The energy losses on the way through the pipes negate the supposed advantage. A kettle heats water specifically and efficiently—directly where it is needed. This not only saves electricity but also money.
Therefore, cold water is the smarter choice—for your health, your wallet, and your kettle. It’s a small step in everyday life that has a big impact in the long term.
