Water heating is a thermodynamic process that uses an energy source to heat water above its initial temperature. When bubbling occurs below the surface, water is simmering. When the surface is in motion and steam is given off, water is boiling.
The loss of gases makes boiled water taste flat or insipid. This flatness can be overcome somewhat by aerating the water after boiling. Aerating water can be easy done by pouring it from one vessel into another and thus mixing air with it.
Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating.
Scalding is a serious concern with any water heating. Human skin burns quickly at high temperature, in less than 5 seconds at 60 °C (140 °F), but much slower at 53°C (127°F) — it takes a full minute for a second degree burn. Older people and children often receive serious scalds due to disabilities or slow reaction times.
