That's the situation where a heat pump is most efficient. I think you could reduce your hot water electricity cost by a factor of 3 by using heat-pumped hot water in the summer, instead of resistive heating. I guess the reason your system doesn't do that in summer is that it would require separate equipment.
With the assumption of outdoor temperature 30°C and water 60°C, the theoretical limit is a factor of about 10.
With so many people experiencing a cost-of-energy crisis at the moment in the UK, it's disappointing that these methods are rarely seen here. I've never seen a heat pump in a home in the UK.

If you were to invest the amount of money that a good crypto setup would cost, a heat-pump with an underground loop would be miles more efficient in the summer than an electric resistance.
Not sure I get where are you going here. There is no mechanical output of the miners, only heat.
> A miner cannot match the heating efficiency of a heat pump
My hot water comes from the heat pump in the winter, when heating kicks in, but the boiler relies on an electric resistance in summer, when the house is mostly in equilibrium with the outside.
