Back when we had visitors I reconsidered the boiler set points and thought I was setting the boiler to perform more closely to typical conditions.
As it got colder this winter it appeared that the settings were keeping the boiler temperatures too low so that it was taking longer to get the house warm.
I went back to the original settings. This is the factory setting and it appears to be better than raising the maximum heat and lowering the outside temperature. Not intuitive to me but the proof is in a warm house with warm floors.
