Here's the formula to calculate the cost to run an electric fire: Cost = Electricity used (kW) x Time (hours) x Unit rate (£ / kWh) Running a 1kW electric fire for 4 hours at a unit rate of £0. 30 per kWh would cost you £1. 20. The economic impact of fire needs to be considered in macro scale, the national impact of fire, and in micro scale, the cost of fire protection and its potential return of investment. The main deciding factor when working out your electricity consumption is the wattage of the heat setting you select. Most electric fireplaces. .
