Steam - Wikiped

Steam is water in the gas phase. It is commonly formed by boiling or evaporating water. 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.. The enthalpy of vaporization is the energy required to turn water into the gaseous form when it increases in volume by 1,700 times ...

Boiler pressure too high? Here’s why & how to reduce it .

Boiler pressure reading as high, only when the heating is on? A combi boiler pressure gauge reading over the 1.5 mark whilst the heating is in full operation, is likely normal due to the water demand being placed on the boiler so it’s likely nothing to worry about. In this instance, a reading between 1.5 – 2.5 bar can be considered normal.
