I have an S-model leaf (no heat pump). I've seen some instructions to insulate heater pipes to improve heater efficiency. But I can't tell if they are only for the 2011/2012 ceramic heater, or also for the later PTC (like my 2017 S). If it's an option for later Leaf S, then I'd like to do that this summer, as the car seemed much slower to warm-up than our ICE did last winter.
