Size the supply coil or heat-pipe bank to the hood exhaust flow, and confirm the make-up air temperature keeps cooks comfortable without over-cooling the space. Demand-based ventilation that follows cooking activity avoids throwing away recovered heat during quiet periods. Keep grease out of the recovery side with proper filtration and a cleanable coil, and respect the grease-duct code for any access and drainage. A smaller make-up air unit often results because pre-conditioning cuts the heating or cooling load.
