How dangerous is it if your boiler pressure is well high

Feb 02, 2010· By boiler pressure, I'm assuming you mean the pressure of the central heating system as a whole, and that the little key you're using is the filling loop from the mains. The key is for *increasing* pressure when, as tends to happen over time, it loses a little. If it loses too much, a safety cutout switches off the boiler, which can be annoying.

Why you can't use high-pressure steam boilers on low

Jun 23, 2014· Why you can't use high-pressure steam boilers on low-pressure steam systems. When the steam's velocity increases (which it surely will when it's at low pressure and aimed at such a little nozzle), the steam will pull the water from the boiler and send it vomiting into the system piping. That causes water hammer,
