This calculation assumes the Heated Anti-Fatigue Mat operates for 8 hours daily and the electricity rate is £0.30 per kWh. During the 8-hour operational period, we estimate that the electricity usage is 0.336 kWh for the initial half hour before the Heated Anti-Fatigue Mat reaches 60°C. Subsequently, the cycling mechanism triggers, and electricity usage drops to 0.206 kWh for the remaining seven and a half hours. Energy costs are therefore approximately £0.51 per day based on the following calculation: £0.30 * (0.336 * 0.5 + 0.206 * 7.5) = £0.51
