Learn why pump efficiency is not only about wattage. This article compares 60 W and 100 W circulation pumps by electricity use, running time, flow, head, and real system performance.
Q:Can a 100 W pump be more efficient for the system than a 60 W pump?
A:A 100 W pump can be more efficient for the system than a 60 W pump if it provides the required flow and head and runs for fewer total hours. A 60 W pump running 24 hours uses 1.44 kWh/day, while a 100 W pump running 12 hours uses 1.2 kWh/day. The real comparison should include working point, running time, and system comfort.
AIKON CMS(L)25-6T1M-I can be used as a reference model for small heating, hot water, floor heating, and light HVAC circulation. Public product data lists this model with 55 / 70 / 100 W power options, max flow 3.3 m³/h, max head 6 m, and DN25 threaded connection. Final selection should be confirmed by actual flow, head, pipe length, system resistance, voltage, and operating schedule.
