        We installed 2 of those, and so far it is best pump for residential hydronic systems by far.

        Nothing really wrong about this pump except for two factors that are deal breakers for me. One, it really is loud. It is. I have my radiant pumps in a utility closet off the living room, and you can hear the thing whine all the time. I replaced them with the Grundfos Alpha, which are absolutely quiet. And two, the Grundfos are about thirty bucks cheaper.

        I wish I had just gone with Grundfos in the first place.

        Taco pumps are great, but with the new technologies, the smart pumps like the Alpha and Bumblebee save 70% or more on the electric bill--electric is the big negative about radiant because the electric to run several zones is quiet expensive. If you live in a tier'ed billing area like I do, where the more electric you use, the higher the cost, the smart pumps can cut your electric bill in half. Mine plummeted, and now I feel great having a radiant system that is truly efficient and green.

        It's a no brainer to get a smart pump. And if you care about noise and initial cost, you won't get a Bumblebee. Why are they more expensive anyway? I doubt they're made better.

        Big savings on electricity

              This little circulator is ideal if you need continuous flow hydronic heat. It can tell the temperature of the supply and return water and will optimize the flow rate to maintain a specified temperature drop. It will then settle on the least amount of power required to do the job. I'm using it to put heat behind tile in a walk in shower in VT. Approx 150 feet of 1/2 inch pex going to the second floor. The pump provides 6.2 gallons per minute at 10 watts. That's right, 10 watts!

              The installation instructions could be more clear (like make sure put the heat sensors on before you start the pump, and the little screw that holds the electrical cover on is too small for words, but other than that this little baby is perfect.

                          Seems to be a very efficient pump but VERY LOUD. An ECM motor certainly makes some rectifier noise, but these pumps are over the top loud, especially at anything other than the lowest speed. The GPM indicator is a gimmick at best as it is far from accurate. Watts indicator is pretty accurate.

                                Replaced an 'older style' circulator that worked fine heating my basement family room, office, and laundry area which was a single loop operating under control of a line voltage thermostat. I initially built the rooms and added this zone in the 70's. I merely swapped out the circulator and operate it in the Delta mode. I can barely hear it when it initially comes on but then it slows way down and is inaudible. I am delighted with my decision to make this purchase.

                                      Put two for separated zones with Weil Mclain Ultra S3 155. Pumps are a bit whiny at the full speed, but they quite down once return temp rises (I'm using then in delta T mode). Easy to install, wire and configure.

                                      Will by two more for additional zones later.

                                            this pump is very loud compared to similar horsepower pumps. i exchanged it for a grunfos alpha and am pleased.

                                                              Others here have complained about the noise. I guess if you had this installed in a living space you would barely hear it, but in a utility room it cannot be heard.

                                                              FYI pump will not spin in delta-T mode until the sensors are hooked up. Also, I had to take my pumps off the day after installation and install the included check valves - I was getting convection flow that was heating my house a couple of degrees with the pumps off - check valves fixed this.

                                                              While I had the pumps off after operating for a day, I noticed the black paint on the inside of the input housing was bubbling up but it has not detached yet. I am a little concerned about the paint coming off and sticking in the check valve.

                                                              The delta-T feature is great. Very low power consumption as the pumps are operating on the slowest speed now (it is late spring here in NJ). Am excited to see how they do in the winter months.
