with power range up to approx. 50 kW (radiator heating systems up to
approx. 500 m² living space, underfloor heating systems up to approx.
200 m² floor space). The power of the ecocirc
adjusted by applying phase trimming ("pulsing") to the supply voltage.

* The benchmark for the most efficient circulators is EEI ≤ 0.20
** Must not freeze. To avoid condensation the fluid temperature
must always be higher than the ambient temperature.
*** Performance of the pump will noticeably change when pumping
water/glycol mixtures with concentrations higher than 20%.
