Re: dose it mean?

Fardin,
It means that in its first year of operation, the system will not save you more money than its purchase, installation, parasitic and maintenance cost. Hopefully, however, your system will last more than one year and so probably in a subsequent year, the fuel cost savings will begin to outweigh the installation costs. Normally, life cycle savings investigations are performed over a 15 to 20 year period.
kind regards,
David

  Dear TRNSYS users

  Good day
  What dose it mean when the life cycles saving in Economic analysis are
totally minus for one-year investigation of water heater or cooling system?
   Dose it mean the system is not economical at all and the system will be
refused to build up?

  Regard and I wish you a merry Christmas
  Fardin
