Does it make sense that an expansion tank be larger with a cold start boiler since the temp swings would be much larger and expansion greater than with a boiler that's always hot? My pressure gauge is only 3 or 4 lbs when it's cold but rises to the high teens when hot. The low number seems too low when cold and on the verge of needing more water to raise th epressure. I leave the makeup valve always closed. The expansion tank is good and there are no leaks. I have a Watts 30 expansion tank, would there be any advantage to upsizing to a 60?
