> Are you aware not using the heater does not affect fuel efficiency in an ICE car? Heaters in ICE cars take the pull existing heat from the engine. It does in many hybrids, particularly those that can operate in EV mode at higher speeds. When heat is commanded, they often will idle under even under no load conditions just to maintain coolant temp. These are conditions which otherwise would use zero fuel. A fun party trick in my hybrid is that I can turn on and off my engine during the winter at a stop light by using the on/off switch for the climate controls. It’s instantaneous. |

Sadly the climate control pre-conditioning on the PiP only uses the battery (or mains, if left plugged in) to cool the interior before you set off, not to heat it. I guess this is because it doesn’t have reverse cycle AC, so can’t pump heat into the interior, only out of it. Far less useful in the UK than California.
So if you want heat, you have to run the engine.
