This depends on the price you pay per kWh, the total wattage of your heating system, and the type of controllability you build in. When dimmed, our heaters run at a lower cost per kWh, offering targeted zonal heating to desired areas. This brings substantial energy savings compared to consistently heating a large space with an outdated gas-fired system all day.
For example, a 1.5kWh heater would cost 37p an hour to run at 100% power according to the UK energy price cap (October 2024). When dimmed at 50% using an energy saving controller, this would lead to energy savings of 18.5p per hour. Adding additional controls such as time lag switches ensure that the heaters will be in use only when needed for a set number of hours, saving substantially compared to a conventional heating system.
