steam

Steam is water in the gas phase. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapour condenses.
Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion.

    Just seen a britony 11 multipoint water heater, its gas valve had jammed open, boiled the water and the resulting steam had blown several soldered joints and fired a section of pipe across the kitchen and filled the house with steam. Never seen anything like it in 30+ years of plumbing.

    Steam coming from boiler outlet

    What does a high level of steam indicate from the boiler vent ? It only happens when the hot water is running. It may just be due to the very cold weather. All is fine with the heating and hot water.
