The article states “It can reportedly provide up to 100% heating output down to -13 F (-25 C) and operate “effectively” down to -22 F (-30 C).”

This does not really tell us much about the performance of the heat pump, we need to know how the actual metrics, including;

– Seasonal Energy Efficiency Ratio (SEER)
– Heating Seasonal Performance Factor (HSPF)
