The ECU is connected to a water heater and an air conditioner, heat pump, or refrigeration compressor. A small pump circulates “cold” water from the bottom of the water heater tank through the heat exchanger within the ECU where it interacts with the hot refrigerant gas from the compressor via a heat exchanger.The resulting heated domestic water is then pumped back to the water heater. Reclaiming waste heat from high compressor discharge temperatures is a proven principle of energy recycling that produces abundant hot water safely and economically.
We offer a dual coil single pump model for when you have two AC or Heat Pump units located near each other, enabling easy compact installations with either or both units returning “free” heated water to the water heater.
