Why It Matters

District heating and utility plants move large heat flows. Capturing waste heat from generation and returning low-grade heat to the network improves fuel use and cuts emissions.

Typical Energy Savings

Reusing industrial or generation waste heat can raise effective system efficiency by 10 to 30 percent depending on the source.

Recommended Technology

• Large plate heat exchangers for network interfaces
• Heat pumps to upgrade low-grade recovered heat

What to Watch

• Temperature levels must match the network
• Seasonal storage can widen the benefit
