I'm able to view the article by clicking the link [0] which goes to [1]. I don't know if this differs for you, or I could be missing something. As I acknowledged, the article is about COP versus temperature. I know don't enough about the state of the art to know whether the article is making a real contribution, or whether it's just some kind of marketing fluff dressed up in academic trappings. Much of the article is spent on repeating feel-good generalities, which is why I'm considering the latter. My main point is that the headline is completely unsupported by the original article. In order to compare heat pump efficiency to a gas boiler efficiency, you have to compare end to end gas->heat, like say a gas power plant powering a heat pump. Looking at the nameplate efficiencies of electricity->heat from a heat pump, and gas->heat of a boiler is fallacious, because electricity is a much more concentrated form of energy. I do believe these numbers have gotten pretty close, which is why such an article would be interesting, but this ain't it.
