There are heat pumps now that use gas to do the supplemental heat. Those are the best possible option. They are equally efficient to a gas furnace when supplementing, and even cheaper when not.

Interesting. A close friend is an engineer who designs HVAC systems (industrial but regardless knowledgeable).
He's told me that the heat pump would pull more power on those days than an equivalent electric only system.
My heat pump definitely uses a lot of power when it's cold.
I wish I had access to the gas based supplemental heating for it. Economically that seems like the best option.
The argument is bullshit in totality. But... When the supplemental electric heating coils come on, it is less efficient ON THAT DAY, than the alternative electric options. But, like I said, in totality, it's more effective over a month, and certainly better over the course of a year. It's a matter of people with an agenda cherry picking the 9 days a year in which it is less efficient and pretending that the other 354 days don't count.
Uh... All I see when I Google that is old porn starring some guy named Mario Salieri
When I was looking at new heat pumps the hybrid ones were between 500 & 1000 more than the equivalent electric ones.
It's not a sperate unit, it just has a gas heater in place of the electric supplemental coils.
