Why does my Alpha boiler keep losing pressure?

Can a boiler lose pressure without a leak?
Boiler Losing Pressure, No Leak In 99% of cases, a boiler losing pressure means a leak — it’s as simple as that. Unless the dial sits at 0 even when topped up (which could be a sign of a faulty pressure gauge), there’s a leak somewhere – even if you can’t see it in the boiler or the heating system.
How often should you need to top up boiler pressure?
