the heat defaults to eco mode on the volt, you have to switch the climate to comfort for real heat.
He did have the heat in high gear. Still cold. (and she was in the back seat, so no butt warmer)
Talked to him yesterday, after getting back from signing papers. He said one thing being debated on the usual volt fora, was a 3 way valve in the heating system, Its supposed to isolate the engine coolant loop from the electric bit. Theory is that they are sticking, so you are dumping kw into warming the engine block along with the cabin.
