Spark Gap electricity-to-gas unit-cost ratio
Heat-pump graphic
Heat-pump and boiler cost comparison with over-time charts, bill-relevant cost comparison, tariff ranking and COP diagnostics
Solar hot water chart showing immersion input for the completed day, cumulative input since 5 April, modeled gas input, net input saved versus immersion, modeled CO2e avoided, input efficiency, and an off-grid garage solar surplus note explaining hot water use instead of curtailment.
Solar generation and payback chart showing daily generation, daily import savings, export earnings, total return including export income, remaining payback, forecast, and summary metrics.
