9 Application Considerations Closed Loop System Closed loop systems (both ground source and surface water) provide heat rejection and heat addition to maintain proper water source temperatures. Operating and maintenace cost are low because an auxillary fossil fuel boiler and cooling tower are not required to maintain the loop temperature.
10 Application Considerations Open Loop System Where an existing or proposed well can provide an ample supply of suitable quality water, ground water systems may be very efficient. (See Figure 7) Operation and benefits are similar to those for closed loop systems.
11 Source Side vs. Load Side Application Considerations Source vs. Load The model WPWD water-to-water system contains two water to refrig- erant heat exchangers. The two heat exchangers enable the system to be divided into a source and load separation.

17 Earth Coupled Application Ball valves should be installed in the supply and return lines for unit isolation. Flexible hoses may be used to connect the water supply and return lines to the water inlets and outlet s. These hoses reduce possible vibration between the unit and the rigid system.
