Sort of, but really we need both. Yes cheaper for most people. But as someone who lives in Minnesota, we definitely get below those temps. By code we require full backup resistive heaters for a heat pump at such a rating which increases the full cost and installation cost. Plus, it is much less efficient than a heat pump (though efficiency lowers as the temp gets colder due to defrost cycles).
