What level of carbon saving is achievable with a hybrid heating system?

Combining your oil heating system with a renewable technology will significantly reduce your household’s carbon emissions. Assuming a household energy requirement for heating of 23,000 kilowatts per annum, a home with a condensing oil boiler running for 90 days and an air source heat pump, with a seasonal performance factor (SPF) of 2.5, running for 275 days, we calculate that the CO2 emissions would be 5,138. This is a 19% reduction compared to using a condensing oil boiler as the only heating source. An air source heat pump with a higher seasonal performance factor would result in even greater savings.
