A building may use air-to-air recovery for the bulk of the ventilation load and an air-to-water loop to serve a distant domestic-water or process load that the air stream cannot reach. Controls should coordinate the two so the water loop does not fight the air core; a simple priority rule keyed to outside-air temperature works well. In a laboratory or mixed-use building, for example, the air-to-air core trims ventilation load while the loop pre-heats service water, and the combined effect shortens payback versus either alone. Keep the loop insulated and the pump sized to design flow to protect efficiency.
