Use this chart to select the proper circulator for your BoilerMate

If a steel hydropneumatic tank is in place, AMTROL

recommends replacing it with a

properly sized EXTROL

or Radiant EXTROL

expansion tank. Otherwise, significant

heat transfer problems can occur by causing air to be trapped in the heat exchanger. If the boiler system has

an EXTROL

or Radiant EXTROL

expansion tank and the boiler temperatures are being changed, resize the

EXTROL

or Radiant EXTROL

expansion tank.
