Replacement suggestions for discontinued WILO circulating pump please

Hello folks, I have found lots of great answers in here, now I have a quick question.  I need to replace a WILO Stratos Eco 16FX circulating pump that has been running nicely for 14 years.  This pump runs the basement floor as well as the brazed plate heat exchanger that does the garage floor as well.  There are shut offs on both the inlet and outlet, so this is an easy replacement.

I’m looking at the WILO star S21 RFC4171560, looks like the same hp and is 3 speed which I actually prefer to the auto sensing on the dead one.  Anybody have a better suggestion, or had good luck with this one?

thank you,
Mark

Thats fine. A Grundfos 15-55 or a Taco 0015e will also work.

The 16 means 16’ head, Star 21 would be 21’. So a bit higher head. Probably not an issue.

Dont you want to stay with a high efficiency style? Plenty of 3 speed ECMs available without all the extra features
