How can I model an electric thermal storage system in E+. The system uses electric resistances to heat refractory bricks during the night and discharges the heat stored during the day, either to the heating water loop (hydronic system) or AHU (air system). I'm more interested in the first configuration where it functions alongside a boiler for example. Do I need to create an entirely new code for this? Any insight on where to start?

From your description, something like Steffes products? I don't think there's anything that specific in EnergyPlus (I would love to be proven wrong). Maybe a proxy solution using hot water storage, as shown here, could be a start. This would need calibrating to mimic solid storage, of course. The example illustrates a solar collector setup, but that's beside the point.

Hi Dennis, Yes, you are correct! I started looking at the hot water storage model you pointed and indeed it looks like it could be tweaked for solid storage. Thank you for this suggestion!

Good to hear Houssem! It would be great to inform readers (including myself) of your tweaked/calibrated solution - in due course. You would be providing an answer to your own question! There is certainly interest in modelling these technologies (and in exploring how to best to operate them under different tarif structures, climates, etc.). Best of luck.
