The governing relationship

Fuel units = useful heat ÷ efficiency ÷ energy per unit

What the result cannot decide

This is transparent planning arithmetic. It does not retrieve live tariffs, weather, equipment specifications, incentives, safety limits, code requirements or professional approvals.

Quick guide

How to use this calculator

  1. Choose the complete example closest to your situation.
  2. Replace every example value with compatible meter, bill, label or planning inputs.
  3. Review the detailed results and the model boundary before making a purchase or project decision.

Calculation method

Transparent energy calculation

Fuel units = useful heat ÷ efficiency ÷ energy per unit

Only the displayed values are used; no hidden tariff, weather profile, equipment curve or incentive is added.

Worked example

Three complete starting scenarios

Complete natural gas scenario.

Fuel units = useful heat ÷ efficiency ÷ energy per unit

Supported inputs

Precision and limits

No live assumptions

This is transparent planning arithmetic. It does not retrieve live tariffs, weather, equipment specifications, incentives, safety limits, code requirements or professional approvals.

Estimates remain scenarios

Actual consumption and cost can differ because of weather, occupancy, controls, maintenance, tariffs and equipment performance.

Safety and compliance

Electrical, fuel, pressure, combustion and installation decisions require applicable manufacturer information, codes and qualified professionals.
