PWFYWith Mitsubishi Electric Cooling and Heating’s variable refrigerant flow PWFY hydronic heat exchanger, a closed-circuit water heater available in two sizes and configurations, daily cost of hot water generation is four times less than with a gas heater and 10 times less than with an electric heater. Using waste heat from the cooling cycle, this exchanger can heat water to 115 F and cool water to 50 F in the HEX configuration. In the booster unit configuration, it works with a compressor to heat water to 160 F. Three operation modes provide a full temperature range based on outdoor ambient temperature, and circulation to prevent pipe freeze.
