What should the pressure be on my boiler while running?

I have a 130k BTU boiler that heats a closed system (not steam) radiator system. When the boiler is cool, the pressure gauge reads 15 PSI - after the boiler runs for 20-30 minutes - the pressure rises up to 19-20 PSI - Is this normal? I understand that water expands when heated, and the job of the expansion tank is to compensate for this.
