Dear all,<div><br></div><div>thank you for your responses and information, I am also new to esp-r as a student carrying out a project. </div><div><br></div><div>@Achim: The idea is to model a water tank in a lightweight building to enhance its thermal mass when it is needed. So the tank will be part of a room's construction directly thermally coupled to store more heat and the water shall be removed when extra thermal mass has no positive contribution.</div>
<div><br></div><div>@Jon Hand: the idea is to have the tank in the room to absorb excessive heat as it would have been cooled down during the night. </div><div><br></div><div>Best regards,</div><div><br></div><div>Panos</div>
