Heat pumps are good for relatively low grade heat production for heating homes and pools. They do not generate hot enough temperatures for efficient generation of electricity. You might be a able to run a small organic rankine cycle turbine with a refrigerant as the working but the efficiency would probably be <15% for electrical generation.
