Why It Matters

Pools lose heat through evaporation and constant ventilation of humid air. Recovery captures energy from that exhaust and slashes the heating bill.

Typical Energy Savings

Exhaust-air recovery combined with a pool heat pump can cut heating energy by 40 to 60 percent.

Recommended Technology

• Plate or rotary exchangers on pool hall ventilation
• Heat-pump desuperheater recovering compressor heat

What to Watch

• Corrosive, chlorine-laden air needs coated, cleanable surfaces
• Control humidity to protect the building fabric
