No, not at all.
I am being told that a heat pump is most eff at 40-45 degree's and your chart seems to suport this with the balance point being at 30. So to me this means that if you live in a climate that has an avg below that during the winter you should not have a HP.
Systems can be set up so that the heat strips can work with the pump simultanteously. (Strips cycle on and off to maintain setpoint)
economic collapse is a certainty. debt based fiat currency monetary systems can never continue indefinitely because they require continuous creation of new debt to service the existing debt. in the absence of economical growth (which is always predicated on increased resource extraction rather than capital alone), this leads to massive inflation which destroys the currency.
your leaders can't fix this - they're corrupt and only exist to enrich themselves and their corporate friends.
