Steam coming from boiler outlet

[marsaday]

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.

Its fine if you have a combi boiler every time you turn on your hot tap the boiler will fire up and steam will come out of the vent.
