Having this heat-pump-or-not dilemma currently. The "Niro EV 4 MY23" will be a 4 year lease but we'd have to pay the full price for the heat pump, so £900 over the 4 years (£18.75/mo). Considering we won't recoup anything in lower depreciation and we'd only benefit the minimal energy cost savings for a maximum of 4 years anyway, it seems stupid to get the heat pump from a purely cost perspective.
However, that's only one factor. Another factor is range. We currently have a MY20 4 trim with a heat pump so we'd be losing range in the winter. Lots of different calculations out there but it sounds as if ~10 miles lost over a ~200 mile trip is a decent estimate in 0-5 C weather. The new Niro has ~3 miles extra range supposedly, so call it ~7 miles lost overall. Our longest trip that we expect to complete in a single charge is ~215 miles, so this could make the difference...maybe? We'd likely only do this trip once a year in winter though so, again, it seems silly to get a heat pump just for that.
Yet another factor is time-to-heat. We'll be doing daily short trips so the lack of a heat pump will presumably mean the cabin will warm up more slowly? It'll surely mean more energy will be used for these trips also (but definitely not £18.75/mo worth of energy!). Maybe this can be mitigated with pre-conditioning but that assumes the car is plugged in each night (or that we remember to manually do it each morning).
I think on balance the heat pump is not worth it, but interested if anyone else decided differently?
