> there's a reason these got virtually phased out! Citation needed. In my country they sell very well nowadays so they don't look as they've been phased out at all. And for good reason IMHO: they are much more rustic than heat pumps and are likely going to live for much longer than the later with cheaper maintenance. Also, as heat can be stored pretty efficiently (and cheaply) compared to electricity, the day/night intermittency isn't so big of a deal.
