Hey Jeff
Thanks for the prompt response.

What I am actually trying to simulate is a PVT system to a
multizone building (2 zones) as you cans ee below.

i have tried running the system for a few days in the winter when heating
is required for the building and the PVT goes above 40C. The first picture
is for when the heating elements in the tank are off:

The second is with heating elements in the tank on:

In both cases, this does not show much effect on the temperature in the
building zones (sun zone and back zone:
With heating elements off:

with heating elements on:

Most probably this is because the building temp is initially at 20 (which
is also the setpoint) so there is not much heat load. What do you think?

Kind regards,
Hadi
