    Technically those are orders of magnitude. 2x or 3x efficiency compared to resistive heating is quite a bit. But in the scheme of getting actual heat into an actual home and real world energy costs it’s not a huge difference

      Order of magnitude is 10x, at least in the common usage of that expression.
