No.
Warming causes changes in the composition of water. The water contains less oxygen and does not taste good. In addition, harmful nitrites may have been formed.
Hot water means water from a water heater (boiler) or from a hot water cylinder in combination with central heating. This water no longer has the quality of drinking water, even if it is cooled afterwards. Warming causes some changes: firstly, the amount of oxygen in the water decreases and nitrites, which are harmful to health, can be formed. The taste is altered and, in addition, some bacteria take advantage of the favourable temperature to grow, especially in parts of the circuit where the water is warm rather than really hot.
This risk is even higher in buildings where there is a combined system for central heating (radiators) and domestic hot water production. If the heat exchanger separating them is defective, the water from one circuit can come into contact with the water from the other circuit.
In addition, hot water accelerates corrosion. It dissolves more easily certain substances (copper, iron, nickel, zinc, …) of the inner walls of the water heaters and pipes and may therefore contain significant traces of these metals.
Tips
Always use cold tap water for drinking, cooking and even making hot drinks. If your kitchen is equipped with a mixer tap, make sure it is in the ‘cold water’ position and do not hesitate to let the water run for a short time in order to purge the tap.
