Condensing vs traditional cast iron boiler? Heating Help

How did you account for the modulation rate of the condensing boiler over the fixed rate of the cast iron boiler? Cause the condensing boiler isn't firing at the same btu rate every day. When its 40 degrees outside the condensing boiler may only be firing at 40,000 btu/hr while your fixed rate cast iron boiler is firing to what it is..

Boiler Systems and Energy Savings | Weil-McLain

Boiler upgrade or replacement is just one way of increasing efficiency. Another way would be running multiple boilers vs. single boiler. Modulating boilers will also improve efficiency by running equipment at reduced loads and thus reducing cycling time (number of starts and stops). "Meter is on the building" - efficiency should not be
