Time Of Day<br />
This graph shows the cost required to generate the hot water to meet the demand shown in the first<br />
graph for various cooling and heating system types. Between 6:00 AM and 5:00 PM, the cooling demand<br />
exceeds the hot water demand. The PFY generates hot water from waste heat used to cool, making<br />
the hot water generation free. When the system is not recovering waste heat, it uses the efficiency of<br />
the CITY MULTI system to meet the hot water demand. An electric hot water heater or a gas hot water<br />
heater has to constantly use electricity and gas to meet the hot water demand.<br />

This graph shows that the daily cost of using <strong>Mitsubishi</strong> Electric's Hydronic Heat Exchanger PWFY<br />
is four times less than that of a gas hot water heater and ten times less than that of an electric hot<br />
water heater.
