New Energy Efficiency Standards Coming into Force in 2028
In a context where reducing energy consumption and operating costs has become a priority, the heating and hydronic circulation industry is evolving rapidly.
In fact, in the United States, the Department of Energy (DOE) has announced that new, more stringent energy efficiency standards and pump motor testing methods will come into effect as early as 2028.
These new requirements will have a direct impact on products currently available on the market—particularly those from Grundfos, a recognized leader in the field of circulation pumps.
Discontinuation of Certain Models
In order to comply with future regulations that will prohibit the manufacture of standard-efficiency pump motors, Grundfos has taken a proactive approach by announcing the immediate discontinuation of the very popular UPS15-58FC and UPS15-58FRC pump models.
Current inventory will therefore be sold through, after which these two pump models will be permanently retired.
Higher-Performance Replacement Solutions
The good news is that Grundfos already offers high-efficiency pumps to replace these models, with no changes to port-to-port dimensions—greatly simplifying the transition for both replacements and new projects.
Here are the two recommended replacement solutions:
UPSe15-58FC (92603106)
Equivalent pump with constant and proportional pressure modes, flanges oriented at 0° – replaces the UPS 15-58FC model (59896341)
UPSE1e-58FRC (92603107)
Equivalent pump with constant and proportional pressure modes, flanges oriented at 90° – replaces the UPS 15-58FRC model (59896343)
Why Switch to High-Efficiency Pumps?
Beyond regulatory compliance, these new generations of pumps offer several tangible benefits:
-
Significant reduction in electrical consumption
(UPS15-58 pumps consume between 60W and 87W, while UPSe 15-58 pumps consume between 3W and 38W) -
Improved hydraulic system control
-
Quieter operation
-
Automatic adaptation to the actual needs of the installation
Conclusion
The evolution of energy efficiency standards marks a major turning point for hydronic systems. New generations of pumps do more than simply circulate water: they actively optimize overall system performance while reducing energy consumption and operating costs.
The Grundfos UPSe 15-58 pumps perfectly embody this transition. With intelligent constant and proportional pressure modes, automatic adaptation to real system demands, and quieter operation, they provide a modern, reliable, and sustainable solution for residential and commercial projects.
