[TRNSYS-users] Heat exchanger UA value

[David BRADLEY]

Martin,
   I would highly recommend that if at all possible you use Type534 from 
the TESS Storage Tank library in place of Type60. Type534 has an 
internal heat exchanger model that is far more robust than the one built 
in to Type60.
Kind regards,
  David
