Yes, heat pumps are more efficient. But they require lots more infrastructure. Not only is that going to be expensive and thus impopular. It will also be a delayed transition, and use up an incredible amount of resources. Not that we should do this instead of heat-pumps. We can do both. Heat-pumps in new houses and if possible when replacing old furnaces. For all the existing stuff, this could be a great stop-gap.
