Preliminary Questions

  • How often do the dryers run (seasonal, hrs/day)?
  • Where is the intake and outlet (air and water)?
  • Where to locate a heat exchanger?
  • How much heat does the deep pool require?
  • How much energy does the deep pool require?
  • Will a heat exchanger be cost-effective?
  • Where is the water heated for the deep pool?
  • What is the cost per gallon-degree to heat water at that point?
