Oxford study proves heat pumps triumph over fossil fuels in the cold::Published Monday in the scientific journal Joule, the research found that heat pumps are two to three times more efficient than their oil and gas counterparts, specifically in temperatures ranging from 10 C to -20 C.

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
