A practical and economical heat pump system stacks the evaporator, compressor, condenser, and expander to use heat from household wastewater more efficiently and effectively. A novel wastewater storage tank treats the wastewater to remove particulates while it supplies its warmest water to the evaporator to provide heat to the refrigerant in the heat pump unit. Heated water exiting the condenser is stored in a separate tank, such as an ordinary hot water heater. The system automatically ensures that the wastewater does not freeze in a substantial amount in the evaporator.
