I think the OP is asking in the context of losing access to or intentionally not buying Russian gas.
So the question should be framed in the context of the timeframe being days not months. If you want to significantly reduce energy consumption instantly, turning the thermostat down is incredibly effective while you work on longer timescale things like insulation and alternate heating sources.
- ciccionamente 5y agoI was thinking exactly this.
- moonchrome 5y agoHow efficient are inverter ACs for heating if it's >0 outside ? Anyone has cost comparison that would ballpark it ?
- bluGill 5y agoDepends, some do a lot better than others, but in general until it is below freezing by a bit heat pumps are overall more efficient.
- hectormalot 5y agoThere is a great (German) database with heat pump performance. You can switch to English on the right top: https://www.waermepumpen-verbrauchsdatenbank.de/index.php?button=verbrauch https://www.waermepumpen-verbrauchsdatenbank.de/index.php?bu... There's quite some monthly data on Air/Water systems (extracting heat from outside air, into a central heating system). I suppose good Air/Air systems could be similar. Indeed above >0, or at least >5C it would be beneficial (even more so if you also have PV installed)
