Small Circulator Pumps with Automated Control

If you missed our last webinar, “Small Circulator Pumps with Automated Control,” you can now access a recording of it on YouTube. You can also view the presentation slides.

Thanks to all the presenters and to participants for their excellent questions, some of which are answered below.

Q&A

Q: Where does it make sense to deploy this type of pump?
A: They are recommended for end-of-life replacement for all small circulator pumps. For DHW applications, they are estimated to be cost-effective if operating more than 40 hours a week. For AHU, they are cost-effective if operating more than 10 hours a day or serving multiple heating coils.

Q: Will a future P100 recommend installing this technology?
A: Small circulator pumps with automated control will not be specified because P100 standards are performance-based and not prescriptive. However, the P100 currently requires that at least one GPG technology is included in new projects, and utilizing this pump could satisfy that requirement.

Q: Does internal pump programming accommodate on/off scheduling for periods when buildings are unoccupied?
A: Pump control does include nighttime setback. If connection to a BAS is not an option, the pump can be controlled through its own interface.
