8) Internal Heat Recovery System
The SCWD compressor unit has a built-in heat recovery system which provides supplemental
domestic water heating at a significant operating cost savings. The heat recovery system operates
throughout the year to provide free hot water when operating in cooling mode and reduced cost hot
water when operating in the heating mode. The heat recovery system supplements hot water
production, but does not replace the standard storage water heater sized for the application.
The Heat Recovery System may be plumbed into an existing standard water heater as illustrated in
Figure 12b.

—Service Connections
Alternatively, the Heat Recovery System may be plumbed to the ETI Series GSTE storage water
heater as shown in Figures 12c and 12d. The Series GSTE storage water heaters are preferred
because the Heat Recovery System ports are designed to provide more efficient heat exchange
within the storage water heater.
