Boiler efficiency, in the simplest terms, represents the difference between the energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units can translate into substantial savings.

Therefore if we assume that the boiler, when operating, burns oil for 65% of the time, then the amount of oil used is 1.48 Litres per hour (= 2.27L X 0.65). As the current cost of oil, including taxes, is approx. €0.81 per Litre, the approximate average fuel cost of running an oil boiler is €1.20 per hour.
