Boiler Efficiency - an overview | ScienceDirect Topics

From Example 8.2, the existing boiler has an excess O 2 of 6% and an overall boiler thermal efficiency of about 78% (i.e., η s t d = 0.78). After the boiler tune-up, the excess O 2 is 3%. Using the monograph of Fig. 8.12, the new boiler efficiency can be determined from the flue gas temperature (343°C or 650°F) and the excess O 2 (3%).

Table Comparing Current Home Heating Costs for Oil, Gas

When servicing oil heating systems we often found that the efficiency of a dirty, poorly tuned oil boiler or furnace might be as low as 60% or even worse. But thorough cleaning and tuning of the same system would bring older equipment up to aroudn 78% efficient (a 30% reduction in heating costs) and on newer higher efficiency systems we could

Electric Boiler Efficiency Explained | Boiler Guide

Gas and oil boilers can't match electric boilers in terms of energy efficiency, as they very rarely achieve an efficiency above 93%. So, in terms of energy efficiency, the electric boiler is the outright leader but the ErP rating is much lower – which is why comparing electric …
