    en.wikipedia.org/wiki/Superheated_water

    The energy required to heat water is significantly lower than that needed to vaporize it, for example for steam distillation [10] and the energy is easier to recycle using heat exchangers. The energy requirements can be calculated from steam tables. For example, to heat water from 25 °C to steam at 250 °C at 1 atm requires 2869 kJ/kg.

    en.wikipedia.org/wiki/Water_heating

    Heat from the space-heating boiler is transferred to the water heater vessel/container by means of a heat exchanger, and the boiler operates at a higher temperature than the potable hot water supply. Most potable water heaters in North America are completely separate from the space heating units, due to the popularity of HVAC / forced air ...

    Latent heat: Turning 0 °C (32 °F) ice to 0 °C (32 °F) water takes the same amount of energy as heating water from 0 °C (32 °F) to 80 °C (176 °F). Leidenfrost effect: Lower temperature boilers can sometimes vaporize water faster than higher temperature boilers.

    Superheating can occur when an undisturbed container of water is heated in a microwave oven. At the time the container is removed, the lack of nucleation sites prevents boiling, leaving the surface calm. However, once the water is disturbed, some of it violently flashes to steam, potentially spraying boiling water out of the container. [6]
