Wilo Star S 21 F 115V 3-Speed Cast Iron Star Series Circulator Pump
I purchased this glycol pump as part of the build your own, which included the manifolds pump, expansion tank, air separator and basic plumbing supplies. I was very happy with how everything arrived together and the install was straightforward just from looking at the pictures. The glycol pump makes it easy to charge the system, and took a lot of the guesswork out of setting it up. My garage now has toasty warm floors.
This is the second unit I’ve installed as the first one, installed two winters ago in another building is working so well. No problems, easy to install. Both systems are hydronic floor heat and these units work great. Just fyi…….going to electric now works out cheaper than the original propane costs. Like that it’s Canadian made.
I bought these to replace some wax actuators from my old system. Those were inconsistent (each moved a different amount) and had huge in rush power requirements. These have low power requirements and appear to be very consistent.
