Grundfos UPSe 15-58F is a high-efficiency cast iron ECM 115V circulator pump with integrated check valve, suitable for almost any hydronic (baseboard/radiator/fan coil), radiant floor heating and cooling application. This model is an improved version of Grundfos's flagship UPS15-58F model, boasting a significantly improved efficiency and (9) modes (3x constant speed/curve, 3x constant pressure and 3x proportional pressure) instead of (3) constant speeds.
One-button operation with (9) operating modes to choose from: (3) constant pressure curves (the head across each zone is constant), (3) proportional pressure curves (the head pressure is reduced at falling heat demand and conversely), and (3) constant curve
High-efficiency ECM motor uses up to 85% less electricity
Built-in removable check valve
Dry-run protection stops the circulator if water is not detected in the system
Automatic self-venting feature helps to prevent air locked circulator and eliminate unwanted noise
Suitable for up to pumping up to 50/50 glycol & water mix solution
Easy troubleshooting with colored LED warnings and alarm lights

While PexUniverse.com reserves the legal right set its own product pricing, some
manufacturers require internet retailers to display a price at or above
manufacturer's established MAP ("Minimum Advertised Price").
Since our price for this product is lower then MAP, the manufacturer does not allow
us to display our lowest price until you place the product in the shopping cart.
This allows us to continue offering our lowest prices while staying consistent with
product manufacturer's policy.
This process does not require you to purchase the product - it can be easily
removed from shopping cart if needed.
We understand that this is an inconvenience and are continually working with
manufacturers to educate them on how MAP affects our customers.
