@seirl_ @juicedpotato @B_helpdesk @Noahpinion @wtogami Heat pumps aren't cost effective in temperate climates when the heating requirements are limited. Then again you wouldn't be mining much in lieu of heat in that climate either.
@seirl_ @juicedpotato @B_helpdesk @Noahpinion @wtogami 在加热要求有限的温带气候中，热泵不具有成本效益。再说一次，在那种气候下，你也不会开采太多来代替热量。
