3 Easy Ways to Reduce Boiler Pressure - wikiHow

Recognize that the pressure is high if the gauge reads higher than 3 bars or 45 psi. The pressure limits and ranges are different for each boiler depending on its size and type, but generally speaking, a pressure gauge should read between 1-2 bars or 15-30 psi.

Sealed system FAQ - DIYWiki - DIY FAQ

The pressure just goes on rising until it is very high, why? Sometimes a filling point control valve can become defective. This will let a trickle of water into the heating circuit so its pressure continues to rise. This continues until either the heating system and mains pressure are similar or the relief valve opens and begins dripping.

Expansion Tanks | Rite Engineering & Manufacturing Corp.

An expansion tank is required on all closed loop heating boiler systems. As a boiler heats the system water, the water will expand in volume. Water cannot be compressed but air can, so an expansion tank uses air (or an inert gas like nitrogen) that acts like a cushion or spring against this force. It is vital that the pressure in the system does not approach the boiler relief valve setting or

How dangerous is it if your boiler pressure is well high

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.
