I think it's better to allow the heatpump to run continuously and use a good t-stat to cycle the aux based on the indoor temp.
The better stats don't work based on a fixed differential.
...when the cop drops below 2 it's probably not worth while.
i agree that hp is better than elec heat but there is a time when running the hp its a waste of powe
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.
