The design limits for the Regusol-X are based on the pressure drop through the heat exchanger, the pump capacity,
and the maximum output of the heat exchanger. The table below lists the maximum number of collectors allowed to
be used with each Regusol-X.

Using an external heat exchanger allows for either multiple or single tank configurations. As long as the storage is
sized correctly the tanks can be in any configuration.

* No more than three (3) OV 5-16 tube collectors are to be piped in series through the Regusol EL130 without a
booster pump.
** No more than two (2) OV 5-16 tube collectors are to be piped in series through the Regusol X without a booster
pump.
