Hi All, I'm trying to use Water Heater as simply HW TES - Hot Water Thermal Energy Storage, that is it has no internal sources.

With 1-Mixed every seems fine With 2-Stratified I've no Boiler energy consumption, Tank temperature progressively goes down, but as a miracle hot water radiator gives the requested heating rate output (please see attached screenshot).

With 2-Stratified I've no heating consumption at all, but Unmet Load Hours are under control (simple ABUPS check, confirmed by Mean -air Temperature analisys of the unique room space , see the scheme here).

I've no idea what is happening . It could be a tremendous bug ?

Did some of you already noticed this?

What do you think about?
