Lifetime Cost Calculator
Cumulative Cost Comparison
Shows how total costs accumulate over 20 years for heat pump vs gas boiler.
Typical 20-Year Costs
ASHP System: £10,000 installation + £1,200/year electricity = £34,000 total
Gas Boiler: £4,000 installation + £1,500/year gas = £34,000 total
With Carbon Tax: Gas boiler could cost +£3,000-5,000 more over 20 years
Break-Even Point: Typically 5-10 years depending on fuel costs and grants
Example: 8kW ASHP vs Gas Boiler (20 Years)
1
Heat pump installation: £10,000
2
Electricity costs (20 yrs @ 3% growth): £26,850
3
Maintenance & repairs: £4,000
4
Heat Pump Total: £40,850 vs Boiler £35,000
