Comparing electricity and kerosene prices
Before installing our ASHP, I wanted to know whether electricity would be more expensive than our old oil boiler. The Nottingham Energy Partnership site had a lot of useful data which helped me compare electricity with kerosene per kWh. What it revealed is that electricity has historically been about 3.8 times more expensive per kWh than kerosene (assuming 90% oil boiler efficiency)...which is just about the same as the advertised SCOP of our ASHP. So I'm expecting to pay about the same, or a bit more, with the ASHP than our old boiler. Hope these charts help with other people's decision making. For us, getting an ASHP was an environmental and not necessarily a cost-saving choice.
