Improving Boiler Efficiency

Improving Boiler Efficiency. Your boiler probably accounts for the majority, if not all, of your heating fuel bill. If you tend to budget a fixed dollar amount for this fuel bill, you may be interested in knowing that most boiler systems are, at best, 85% efficient with an average efficiency of only 65% to 75%.

Efficiency is the percentage of output from the input. No boiler is 100% efficient, as the boiler itself requires some energy to operate, and even the most efficient condenser boiler will inevitably lose a bit of heat to the atmosphere. But at around 90% efficiency, most modern boilers do a pretty good job of getting close to perfect.
