If the two coils are piped in series, the pressure drops are
cumulative. Pressure drop of connecting pipe must be
added.
If they are piped in parallel, a separate pump is
recommended for each coil. Otherwise, flow setters are
needed to regulate the flow through the two coils.
Ensure that in any case the pumps meet the load.
