as far as I can tell from the free accessible part: their analysis seem to only make sense if you assume that Covid magically went away and/or Covid death are reliably detected even if the person dies at home in a context where "ways through which covid can kill you" happen to also be what they base their analysis on... but at least personally I know of more cases of more serve Covid last winter then pretty much any time before, not very surprising given that Covid didn't disappear, still mutates but Germany had noticeable less steps to prevent Covid then before and this are all cases which didn't in anyway decrease their usage of heat (i.e. earned enough to be able to cope with increased heating bills) so idk. but from the parts which are not behind a paywall this looks like a very questionable analysis, which also happen to fit multiple political agendas very well, surely just coincidence but interesting anyway
