英国家庭光伏余电：热水用热泵比浸入式分流器更划算
Surplus PV in UK homes: why the heat pump beats the immersion diverter for hot water
英国屋顶光伏余电的常见去处是浸入式分流器，但在改用空气源热泵的家庭中，同样1 kWh电力经热泵可产出数倍热量，而浸入式加热器只能产出1 kWh热量。英国“电气化供热”示范项目对291台空气源热泵的中期分析测得季节性性能系数中位数为2.80。按Ofgem 2026年10月至12月26.32 p/kWh的电价上限计算，余电供热泵约可省26.32 p，供浸入式加热器仅约省9.4 p。

In UK homes with heat pumps and solar panels, directing surplus solar electricity to the heat pump can deliver nearly three times the savings of traditional immersion diverters. Maximising savings depends on smart controls, export tariffs, battery priorities and efficient hot water scheduling.
