How dangerous is it if your boiler pressure is well high? |

if you're boiler manual says it's maximum pressure is at or below 3 bar then fair enough (virtually all boiler manuals are available online), but every boiler installation should have a pressure relief valve that's set to relieve pressure before it becomes dangerous anyway, so it's very unlikely to be at a dangerous level.
