Reply to comment by RatherNott in Is wood cheaper than oil? by wholeWheatButterfly

Well aware thanks very much. What you are ignoring as that while yes they will make heat at -22 they do it very inefficiently. Plenty of charts out there that show this. Or just ask someone who has one how they work at that temp and you will get the same answer. Not all that great or maybe ok for supplemental.

That's true, but I would argue the efficiency with those latest units make them viable for most households in Vermont as the main source of heat for the majority of the winter/fall/spring, as the amount of days where it is truly cold enough to make a modern heat pump struggle are so few, one could easily switch to a back-up source of heat for those, yet still gain the efficiency gains for the rest of the year.

Not to sure about most as we have lots of older poor housing stock here. That's lots of poorly insulated homes and what comes with it. I do think they are better utilized in a newer home that is much better insulated however lots of people get these as a way to save cash in an older home or much larger area than they are rated for and become disappointed pretty quickly. Even with the rebates. At least we have not had the electric rates double like Mass and NH and have. Double the heat bill right there ouch.
