What is the correct temp setting for a hot water boiler

If you set your boiler operating temperature below that for extended periods the flue gasses will condense, form acidic deposits and eat the boiler. So one must spend energy to maintain temperatures higher than that. By this it means that your range of setting the boiler down when it gets warmer out is between say, 180 and 140. (Yawn.)

When using this type of control, the boiler's supply temperature decreases as the outdoor temperature rises, thus ensuring lower return water temperatures. The desired outcome is the matching of space heating needs with the heat delivered.
