> Using resistive heating (which is what this is) is not very efficient (even if it's a by-product).
If heat is a byproduct it is highly efficient to actually use it rather than waste it. Here the electricity would be used either way for the processing tasks. The system would be inefficient if it just ran busy wait to produce heat, but that's not the case.
> A better way to heat your home is to not waste power and use it instead to run an electric heat pump (which are over 100% efficient).
"100% efficient" makes no sense, let alone "over 100% efficient", you're talking about coefficient of performance (the device's energetic ROI). If you ignore what the system is actually doing, the eRadiator thing has infinite efficiency since you're not paying for any heating (aside from installation costs, which you also have to pay for a heat pump)
That's not how thermal efficiency works. And if you don't care for actual thermal efficiency, the energy taken from the wall plug is irrelevant if you're not paying for it.
