It depends what you mean by the alternative electric options. Electric resistance heating is 100% efficient and that's what my heatpump effectively is when it gets cold enough. It's not less efficient than wall mounted electric radiators even when it drops to -30C. You just lose the efficiency of a heatpump for that time.
Exactly - people somehow fail to understand that Heat Pumps, by necessity, are always more efficient than 100% of an equivalent electric solution.
