Heat Cascade Planner
Use exhaust HX (high-temp), jacket HX (mid-temp), and plate HX (low-grade) to reach ~80–85% total utilization. No wasted heat.

Heat Cascade Best Practices
- • Match high-temperature needs to exhaust heat first (drying, sterilization)
- • Use jacket water for space heating, greenhouses, and mid-temp processes
- • Capture low-grade heat for preheating, floor heating, or aquaculture
- • Consider thermal storage to balance supply/demand timing mismatches
- • Monitor actual vs design performance—real efficiency often differs
