If the two heat exchangers are piped in series, the
pressure drops are cumulative.
If they are operated in parallel, a separate pump is
recommended for each heat exchanger. Otherwise, flow
setters are needed to regulate the flow through the two
heat exchangers.
Ensure that in any case the pumps meet the load.
