EnergyPlus can model Solar Collectors directly but not greywater heat recovery.
You will need to model the greywater heat recovery separately. I suggest modeling it as a DistrictHeating object with a Source Temperature Schedule that you will need to calculate yourself from your hot water assumptions, and then import into your model with a Schedule:File object. You will add this DistrictHeating object to your service hot water loop.
