Electric heating is 100% efficient from power point onwards
on 9 December 2016
Outputs as much energy as it takes in - electric heating is effectively 100% efficient from power point onwards. I find it enough to adequately heat a medium size living room (about 4m x 4m) in winter to around 21C, if left on for about a third of the day. Make of that what you will, but this is cheap to run and unobtrusive.
Main downside is the loud and regular clicking from the built in thermostat. You soon get used to it though.
