I agree that thinking is outdated, however...
The last time this topic came up, people with heat pumps said they needed to supplement their heating when having multiple days of -15F, some even said below +15F. Maybe newer heat pumps can work well enough down to these temps but the ones most people have already in their homes do not and require additional heating. There are many other factors to consider as well when determining cost-effectiveness, especially in houses with existing duct work, it's not as simple as one just being more efficient than the other. And anyone that gets caught up by that may be served well to apply a bit more critical thinking because heat pumps are not always the best solution.
Saving power for even a few extra months still saves money. You can have both a heat pump and a normal gas furnace. They aren't even that expensive. If you have a high heating bill, it could pay itself off in a few years.
Sure.... but there are a lot of variables to consider because heat pumps are not the most cost-effective solution for every situation. Too many people seem to think it is cut and dry and heat pumps are the best solution, but again, not always.
