What Effect Does Low Pressure Have on My Boiler?

Most people do not know that low pressure in a boiler can have a drastic effect on it's longevity, and many have concerns over whether low boiler pressure is dangerous. A boiler can lose pressure for multiple reasons, it can be due to a leak in the pressure relief valve, an issue in the expansion vessel, air in the system, or a leak in the heating pipework.
