With all being correct you should not see much change in pressure when the water heats up. From a cold start to 180f you may see a 5 psi change. Sounds like you may have a low air charge or too small of a tank. What type of radiation do you have? This makes a differance. What size boiler? What is the tank pressure? This must be checked with "0" water pressure. The above information would allow us to better assist you.
