    100 ft. Closed loop, conventional boiler 1" pex. Had a taco 007, capacitor blew, want to upgrade. Thanks!

    Taco warranty sucks now, stay away from them.

    B&G NRF-22 is a decent step up from a 007 at about the same price. NRf-25 is one notch more with 3 speed option.

    Is that 100' one way or round trip? Did the 007 handle things OK (move enough heat) prior to konking out? How long did it last? What do you have for a boiler? 'Conventional' to me means pressurized & indoors.

    A Grundfos 15-58 3 speed is a very good circ and reasonable price - not sure though without looking exactly how pump curves compare & if you might benefit from a more capable one or not. 1" pex can present some head, plus whatever else is in the loop.

    Then I would agree with using a 15-58, or NRF-22. Both are a higher head circulator (than the 007) that should handle the 1" pex fine.
