Comments about Star S 21FX, 3-Speed Cast Iron Star Series Circulator, 1/12 HP:
I use this product to pump hot water from a outside wood burning boiler into an inside boiler to heat my home. The three speeds allow me to regulate the temperature of my home.
Bottom Line Yes, I would recommend this to a friend

The Wilo Star S21FX pumps are the best pumps I have ever used. they are quiet and powerful. The castings are heavy and the supplied gaskets are nice and thick. Having only 2 cap screws to change motor position is a real timesaver. The no-tools electrical connection is a real plus as well.
good multifunction pump
from Sudbury, ma
Good for pumping primary loop on small mod/con boiler on speed 3, as well as zoning fin tube baseboard with speed 1. Make your selection for radiant, cast iron, or steel panel based on your head loss calculation,etc.
By Keeping It Warm
Very well built. Easy to change orientation. Easy to wire up. Great pumping capacity. Very quiet operation.
Well built pump
Easy to install. With only 2 cap screws to remove to reposition motor it is a real timesaver. Quiet running and powerful.Nice thick gaskets supplied with unit. Easy, no tools electrical connections.
from cincinnati, oh
I use these pumps to replace the original one speed pumps used on my wood boiler. The 3 speed allows you to choose the water flow needed to provide heat for the home. In my case the lowest setting works fine and it uses less electricy.
Would buy again.
from Wartrace, TN
I installed this pump on my Hardy wood furnace. I have approximately 175 ft of 3/4 pipe with a 20 ft. rise straight up to my attic. It does the job as well as the expensive Taco I replaced.
