  6. An old gas-boiler has an energy-efficiency of 65% and a new one 93% resulting in a 30% energy reduction and consequently a 30% CO2-reduction, if installing a wood-chips or pellets boiler the savings will be increased efficiency + cheaper fuel resulting in a total saving of 40–50% and a CO2-reduction of 100% (renewable energy), if installing an efficient heat-pump the savings and the reduction will both be around 80% (100% CO2 reduction if the electricity comes from renewable energy).
