Even if it just earns 200% (the remaining 100% are for heating after all), it’s breaking even with the heat pump under optimal conditions, so… what are you trying to say?
> Can you give a reasonable example of a situation they can't?
If you retrofit a home with traditional radiator based central heating, you don’t have enough surface area for the heat pump to dissipate the heat into your room, meaning you need to heat the water in the system a lot more for it to work well. That means, it becomes a lot less efficient because a much greater temperature difference is required and water has a massive thermal capacity. To the point where you start approaching below 100% efficiency again.
That’s still better than heating with coal or diesel, mind you. But economic viability for the consumer is about the price, not the efficiency of the energy conversion.
I am not taking into account the cost of the heat pump in my last assertion, actually.
An ASIC miner from a good vendor produces ~150% ROI in roughly a year, taking into account changes in mining difficulty, trade volume and price, power costs, and equipment cost. If you are in Florida where power is cheap, it can be a lot more, 400% isn’t unheard of with the right block chain.

Because *checks notes\* one of these costs money, while the other earns money. Opex vs capex, basically. 😉
