Easy ECM – Easy to install. Easy to program.

The 0034e & 0034ePlus ECM High-Efficiency Circulators are high-performance, variable speed, wet-rotor circulators with high-efficiency ECM permanent magnet technology. Their variable speed performance curves are equivalent to the Taco 009, 0010, 0011, 0012, 0012 3-Speed, 0013, 0013 3-Speed & 0014. Ideal for large residential and light commercial hydronic heating, chilled water cooling and domestic hot water systems. The ECM technology reduces power consumption by up to 85% compared to equivalent AC permanent split capacitor circulators. The 0034e comes with an easy-to-use dial while the 0034ePlus has an intuitive digital user interface.
