Julien,
  solar water heating systems with variable volume tanks are somewhat 
rare - typically a constant volume tank is used. However, Type39 should 
not be generating an "invalid floating point" error. Could you please 
send me your *.tpf and any other files that I might need in order to run 
your simulation?
Thanks in advance,
 David
