Good Energy: Heat Pumps Excel in Winter Conditions
Air source heat pumps can effectively heat homes even in sub-zero temperatures. Good Energy addresses concerns about air source heat pump performance in winter, stating their heat pumps can maintain warmth in temperatures as low as -15°C due to the refrigerant's low boiling point. The original article from Good Energy explains that these systems draw in outside air, pass it over a refrigerant, and compress it to transfer heat, even when external temperatures are low.
With an average year-round efficiency (SCOP) of approximately 360%, the article emphasises that while seasonal performance varies, the majority of a heat pump's annual energy use aligns with traditional heating patterns between October and March. To maintain efficiency, Good Energy advises annual radiator bleeding, system pressure checks, regular filter cleaning, and steady, lower-temperature operation. Further instructions for these steps can be found here.
In conclusion, while cold weather performance remains a key consideration, air source heat pumps offer a viable heating solution, particularly when optimised with expert recommendations. Readers evaluating heat pump technology for their properties should consider these factors. To read a comparison of heat pump efficiency in summer versus winter, click here.
