Hi All,

I need to model a closed loop ground water well. The ground water well feeds water to heat pumps for both hot and chilled water. As this isn’t a traditional ground source heat pump, the heat/cold is coming from the well water rather than the earth, I have been trying to figure out which would be a more appropriate component to model this. My two options at the moment are - “GroundHeatExchanger:Pond” or “WaterHeater:Mixed”?

My question is due to the description of the “GroundHeatExchanger:Pond” component in the I/O reference as a ‘shallow’ pond. This implies that the water temperature around the pipes would vary much more than a well water system and would not provide the correct heat transfer.

The "WaterHeater:Mixed" would allow us to heat the water year round on a schedule to 15°C (or similar) and control the temperatures more.

Does anyone know of any other options or whether there are further considerations to take into account with these two objects?

Thank you in advance,

Raghu
