Smart circulation pump EPA ESN2/U25-4-180 (22 W)

This is a smart circulation pump that keeps water moving continuously in hot water and heating systems — in radiator and underfloor heating circuits. Its inverter-controlled motor adjusts speed to the system's demand, keeping consumption at around 22 W with no wasted electricity. A three-step button on the control panel allows speed to be selected by hand, while in auto mode the pump chooses its own operating mode. Its ability to handle hot water up to 110 °C allows installation directly in boiler rooms and heating circuits.

Advantages

Inverter-controlled motor — matches speed to system demand, with no wasted electricity
Low power draw (≈22 W) — keeps running costs minimal even in continuous operation
42 L/min (≈2.5 m³/h) flow and 4 m head — fully circulates small and medium circuits
Auto mode — the pump chooses its own operating mode, with no need to switch speeds by hand
Three-step speed button and indicator — a low setting for underfloor heating, a high one for radiator systems
Winding of solid copper wire — improves motor durability and extends service life
Textolite impeller — withstands temperatures up to 110 °C and system pressure without losing its shape
Thermal cut-out against overheating — the pump stops by itself if the motor gets too hot
DN25 connection diameter and 180 mm installation length — quick fitting to standard pipework without adapters

Application

Used to circulate water in radiator and underfloor heating circuits. In hot water supply networks it maintains a constant circulating flow so hot water arrives at the tap immediately; in closed circuits it distributes water evenly and delivers heat uniformly. Intended for smaller systems and homes with radiator heating.

Note on use

The pump must not be started dry — switch it on only after the system has been filled completely with water. Until the air has cleared from the system the pump runs with some noise, after which it continues running silently.
