I don't think Slate has confirmed whether the Slate truck has a heat pump or resistive heater. Hope they somehow managed to include a heat pump for the $27K price.
I read somewhere that a heat pump had been confirmed. It seems like it would be a crucial part of an already small battery short range vehicle not losing too much range in adverse weather.
Hopefully it wil. Be a heat pump as it’s mainly just a valve on the AC reversing the coils. Should be minimal cost but when I reached out the response was negative. Maybe that will change.
