Unfortunately heat pumps are not very good at producing power from small heat differences. In industrial plants, any waste heat stream that's below 100C is considered "low grade" and mostly used for heating office buildings etc.

Still the way a heat pump in a HVAC system works you turn a small temperature difference into larger difference through the "A" coil, essentially compressing the warm air to make it hot, but I guess this does not scale well.
