Oxford study proves heat pumps triumph over fossil fuels in the cold

This is a most excellent place for technology news and articles.
Excellent. Now I know that there are different classes of heat pump. Mine is not for prolonged crazy-low temps, others are. Thank you.
Indeed, but yours is probably cheaper and more effective at cooling when it's hot and humid out.
For people up north, they will buy a "cold climate air source heat pump". In temperate regions, an "air source heat pump" will suffice, while down south you will buy an "A/C with a heating mode" (also called reversible A/C).
And it's not just about whether the coils can defrost. The whole machinery and refrigerant are different to optimize under those conditions. A cold climate heat pump has a setup that is more similar to a freezer than it is to an A/C.
Sorry about the downvotes. People need to re-learn internet etiquette.
This is the most informative answer yet. Thanks.
Thanks for spreading correct knowledge, as someone who works for a manufacturer of heat pumps it's refreshing
