So... Where do we get 45 million plug-in heaters? And to replace a 20kW gas heater you'll need _slightly_ more than 1 1.5kW plug-in heater. Yes.. it's a component. Yes I'm sure it will be employed. Yes it will stress the electric grid (but there is much more flexibility available). But it's not the solution to the majority of gas heating, because there simply isn't the capacity to get the required amount of hardware in the available time.

Those gas heaters are usually overdimensioned by a few factors. Nobody needs to fill instantly fill a bathtubs with 60 degrees. My house came with an 14kW gas unit, but a 5kW heatpump is enough for cold winters. Naturally the unit will be running for longer, but that's an efficiency in itself (lower delta T). Assuming a conservative COP of 4, that comes down to 1.25kW primary electricity consumption. It's a no brainer.
