Description
–
The ALPHA 15-55 HWR-T is a hot water recirculation pump that operates using a wireless temperature sensor that functions like an aquastat. The pump will activate via the programmable timer in addition to the measured return line temperature. The sensor keeps the water temperature within an optimal range that is calculated every 12 hours. Perfect for homes with multiple occupants and unpredictable hot water usage. This innovative design is built on the current Grundfos ALPHA platform, offering high energy savings, low noise levels and a quick installation.

The "learning" control is bad. Don't purchase.
The "learning" feature on this pump isn't effective. Review the "Control Functions" section in the IO manual if considering.
The Learn Time, Tstart, and Tstop are not adjustable. If these presets work in your application that's great but they didn't in mine and the pump doesn't run enough. It's maddening to have a pump that has sufficient power to get the job done and it's "smart" controls keep the pump from running enough.
I will not purchase this pump again.

Pump works well but........
The timer is inflexible and does not measure up to expectations.
Grundfos should provide a few drops of heat conducting grease for use with the temperature sensor.
Buy the pump, skip the timer. You can get a better one elsewhere.

I might buy again if temperature sensor issue is fixed
The actual pump works great, but the temperature sensor does not. The sensor was paired with the pump but the pump never came on. As a work around, I removed the battery from the sensor so that the pump operates for 5 minutes, shuts off for 15 minutes and runs again for 5 minutes. By doing this, the hot water circulates through the system.

Product Q&A
1 Question1 Question
Q: Greetings, I'm interested in purchasing this water pump for my laboratory's condensation setup, but I have several questions regarding its specifications and usage: Can this pump operate efficiently with chilled water at a working temperature of 50 F? Is this pump equipped with a variable frequency drive? If it is, could you please provide information about the flow rate range and the accuracy of this drive? Is implementing a water tank necessary before the pump's operation? I look forward to your response.
