Heater Cost Calculator
Calculate what an electric heater costs to run per hour, day and month.
How it is calculated
Energy = watts × heaters × hours × thermostat on-time ÷ 1,000. Every electric resistance heater turns 1 kWh into 1 kWh of heat – “efficient” claims only change how that heat is delivered.
Results are estimates for planning, not bills or professional advice. For generator or inverter hookups use a changeover switch installed by a registered electrician with a certificate of compliance (CoC).
