My Boiler Pressure is Too High? A 24|7 Home Rescue Guide

We often say that a boiler’s pressure should be at around one bar, but this is only when your central heating is turned off and you are not running any hot water. When your boiler starts heating up water, the water expands (think of how steam takes up more space than water), which causes the pressure gauge to jump up.

Superheated Steam Water Tube Marine Boilers

Marine boilers produce high pressure superheated steam to drive the turbines. The steam is generated by the water tubes which connect the water drum to the steam drum. Water and steam circulate through the vertical banks of tubes; the inner ones supplying the top drum and the outer ones dropping steam and water back to the water drum.
