Heating System Comparison Calculator
Compare lifetime cost of different heating systems.
Compare lifetime cost of gas boiler vs heat pump vs electric heating. See full ownership cost over typical 15-year lifespan.
What this tool does
Enter system A cost, system B cost, annual running cost A, annual running cost B, and lifespan. The tool shows lifetime cost of each.

Results are estimates for educational purposes only. They do not constitute financial advice. Consult a qualified professional before making financial decisions.
Heating system choice has long financial implications. Gas boiler 2,500-4,500 + 1,500/year running. Heat pump 8,000-15,000 + 800/year running. Electric 1,500 + 2,500/year running. Over 15 years, totals diverge significantly.
What the result means
Lifetime cost of each system. Cheaper option wins. Often heat pump cheapest long-term despite higher install. Gas competitive shorter-term. Electric typically most expensive.
A worked example
Try the defaults: system a install cost of 3,500, system a annual running of 1,500, system b install cost of 12,000, system b annual running of 800. The tool returns System B. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to System A Install Cost, System A Annual Running, System B Install Cost, System B Annual Running, and Lifespan. Two inputs usually tip the answer one way or the other. Identify which ones matter most by flipping each value past a round threshold and watching whether the winning option changes.
The formula behind this
Each lifetime = install + annual × years. Lower wins. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
Cost vs value in green choices
Sustainable options usually cost more upfront and less over time. This tool separates the two so the comparison is fair — looking at purchase price alone consistently makes the green option look worse than it is once lifetime costs are tallied.
What this doesn't capture
Carbon reduction, health benefits, and local air quality have real value the financial figure doesn't price. The calculation gives the money side honestly; for the full picture, note the non-financial benefits alongside.
Heating systems produce lifetime comparison based on the inputs provided.
