: : ++++ If the house is warm enough when the weather gets coldest, then the burner input is too large, the boiler can't get rid of the heat fast enough, so the water reaches the high limit temperature.
: Not sure if I am misinterpreting this but does that mean a "right sized" system would leave the house not warm enough on the coldest days?

The biggest problem that I have is finding someone in the Indianapolis area that is competent and can be trusted on residential boiler systems. Don't know where I can get a good recommendation do you?
Someone on this site might. Call some plumbing/heating supply houses, they might.
