I would like to ask a question, i am modelling a water to water heat pump in energyPlus and my heating plant loop has equal inlet and outlet temperature on the supply side. Additionally, the demand energy rate of this plant loop is zero. I would be greatly thankful for anyone can help or have any idea about what could be the problem.

Many thanks, Best regards,

@Qamar it's hard to say what's causing this without seeing the model. Can you upload the IDF and EPW files you're using to Dropbox, Google Drive, or something similar and share the URL for others to download them?

However, if there is no energy, then the supply and inlet temps will be equal. I'd look at your plant definitions and see why there is no load. For Air loops, I see this when the zone setpoint is high and the cooling is not needed.
