That's resistive heating, which is the most inefficient means of heating. Worse than natural gas or heating oil, and much worse than a heat pump.

Worse than a heat pump, yes, but very arguable whether NG is more efficient. Arguably, NG powering central electric power generation and then used for resistive would be overall more efficient. Central NG will be more efficient and also there’s substantially less opportunity for NG leakage if piping was reduced.
NG is definitely cheaper (at least in the US), but that’s not really related to efficiency or emissions cost.
