How does using an electric heater instead of waste heat from electrical appliances reduce the use of fossil fuels? Same transport mechanism, same source, same efficiency.
The only way to reduce electricity consumption is improved insulation.
I agree with you if you have a wood-burning stove.
If you use a standard electric heater, like a bar heater, I agree with you.
Heat pumps can out-perform heaters (they seem to have >100% “efficiency”) by working in a different way. Rather than spending 1kWh to heat a room, you spend 1kWh to move 4kWh of heat from outside into the room.
