As evident in Figures 6 through 8, a condensing plant has higher efficiency than a traditional
boiler plant due to blending of low temperature return water from the SmartPlate.
The plant efficiencies can be further improved by utilizing dual return boilers such as AERCO
Benchmark. Instead of blending the low temperature SmartPlate water with high temperature
system return, it would be an efficiency gain to pipe the lower return to the Primary inlet (or
standard inlet, at the base) and piping the higher temperature return to the Secondary (or
higher) inlet. This will allow the boiler heat exchanger to condense more due to the low
temperature return of SmartPlate system. Such applications can have efficiency gains up to 6%
depending on the flow rate rations and return water temperature.
Refer to Figure 9 for a variation of Figure 4 but with Benchmark dual returns.
