Heat pumps outperform gas even in coldest temperatures, finds Canadian researcher

Oct. 11, 2023 -A study, published in the journal Joule, examined the efficiency of air-source heat pumps in sub-zero scenarios down to minus 10 degrees Celsius — “mild cold climates” similar to the populated coastal regions of British Columbia.
