A ventilating, cooling, and heat reclaiming system for use with cooking equipment such as commercial ranges and grills whereby grease laden exhaust air passes through a grease filter or extractor and then past a cooling coil through which water is circulated so as to improve grease removal and reclaim heat from exhaust air to heat outdoor supply air. The heated water from the coil is supplied to a further coil disposed in the path of outdoor supply air via a three way valve having two outlets and a mixing valve. The mixing valve varies temperature of water in the further coil to maintain constant the temperature of the supply air and water not supplied to the further coil is supplied to a hot water generator by the three way valve.
