Wilo Star S 21 RFC circulator pump incorporates a cast iron housing, three speed motor (Low/Med/High) and a built-in, removable check valve. Wilo Star S 21 RFC is among the most popular and most versatile circulator pump models on the market. Pump’s performance parameters cover nearly all traditional heating applications – from radiant and baseboards, to fan coils and zoning and many others. 3 speeds allow to set up the circulator pump in a way, that matches the system’s requirements, while wet rotor design allows it to be virtually silent while operating.

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.
