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%.

Improve Your Boiler's Combustion Efficiency

Condensing boilers have the potential to reduce gas consumption for space heating by as much as 15%, providing they are carefully selected, monitored, controlled and maintained. A typical condensing boiler has a thermal efficiency of 92-95%, in comparison to non-condensing boilers which typically have efficiencies of around 85%.
