Resistive heaters still suck though because Heat pumps give you 200-400% efficiency. So heating wise, “100%” still less than maximally efficient.

(Not a violation of thermodynamics btw. Heat pumps use electricity to move heat energy that already exists, so the electric power in is often significantly smaller than the heat coming out of the device)

No he'll be criticizing your choice of Christmas string lights, or lack thereof.
