<p class="MsoNormal"><span style="color:#1F497D">To properly model steam systems in eQUEST I’ve added a process load that accounts for: make up water and the deaerator. The total energy impact can be significant (20-30%) depending on your system design.

<p class="MsoNormal"><span style="color:#1F497D">While we’re on the topic of steam systems in eQUEST. It would be nice if you could have a separate boiler system for the humidifier from the heating hot water system. We’ve been using heat recovery chillers and
condensing boilers for a lot of projects lately that generate 130F hot water with separate process steam boilers for humidification and/or sterilizers to be more energy efficient, which currently can’t be modeled in eQUEST.
