At ökoform, their goal is to provide comfortable, well-heated working environments across the country for a fraction of the average heating costs of standard gas and electric heating options. For every fan heater removed from your office, you could be saving around £46.50 per week (based on October 2022 energy pricing £0.52kWh, 8 hour working day, five days a week). The average desk fan heater uses 2500 – 3000 watts. At just 260 watts, our desks are 90% cheaper to run.
