Is there any detail on heat output efficiency. ( ie cost per hour on 2 kw )

Thanks for your enquiry.

The ACR Neo 3CE electric stove offers a 1 kW or 2 kW heat output with close to 100% efficiency, meaning almost all the electricity used is converted to heat. At the current UK average rate of around 25.7p per kWh, the cost to run at 2 kW is approximately 51p per hour (half that on the 1 kW setting).
