How a rural cottage replaced expensive oil heating with a heat pump, saving £1,240 annually and eliminating fossil fuel dependence.
Annual oil costs ranged from £1,800 (2020) to £3,200 (2022 peak), making budgeting impossible. Average 2023/24: £2,250 for 2,500 litres @ 90p/litre.
Minimum 500-litre deliveries (£450-£550) required twice yearly, creating cash flow challenges. Tank monitoring anxiety about running out before next delivery.
7.5 tonnes CO₂ emissions annually from oil heating. Homeowners wanted to reduce carbon footprint and align with net zero goals.
15-year-old boiler requiring increasing repairs (£320 in 2023, £180 in 2024). Oil tank showing minor corrosion, replacement estimated £1,500-£2,000 within 5 years.
Rural West Dorset location, 4 miles from nearest mains gas. Connection cost quoted at £18,000-£25,000 - economically unviable.
Rural cottage with cavity wall construction, loft insulation (200mm), double glazing throughout. Exposed location on hill required wind exposure adjustment. Total heat demand: 11.5kW @ -3°C design temperature.
Drained 400 litres remaining oil (sold back to supplier @ 70p/litre, £280 credit). Removed 1,200-litre steel tank, cut and disposed of responsibly. Cleared concrete base, restored garden area with topsoil and turf.
Existing radiator system was well-sized (installed 2015 during renovation). Flushed system thoroughly to remove sludge/deposits. Installed 300L unvented hot water cylinder replacing old vented tank. Added weather compensation controls and smart thermostat.
Positioned on north side of property (previously oil tank location), 25m from nearest neighbour. Concrete base 1.2m × 0.8m with anti-vibration pads. Refrigerant pipes run through external wall into utility room.
Existing consumer unit had capacity for heat pump circuit. Installed dedicated 32A MCB and 6mm² supply cable. Upgraded to smart meter (included free by energy supplier) for accurate monitoring.
Note: Savings increased to £1,360/year after switching to Octopus Cosy tariff (12p/kWh off-peak, 27p peak). Heat pump scheduled to run primarily during off-peak periods.
"Switching from oil to a heat pump was the best decision we've made for our home. We're saving over £1,200 per year - money we're now investing in other home improvements.
No more anxiety about oil deliveries, price fluctuations, or running out mid-winter. The heat pump just works quietly and efficiently. Our house is warmer and more comfortable than it ever was with oil, and we love knowing our heating is now powered by renewable electricity.
The installation was professional and completed in 5 days as promised. The team explained everything clearly and patiently answered all our questions. One year on, the system has performed flawlessly through summer and winter.
For anyone in rural Dorset still burning oil - make the switch. You'll never look back!"
