1) Recommended value for the most effective pumps: EEI ≤ 0.20
2) The flow rate and residual head depend on the connected heat pump or in case of hydraulic separation. See table 15 and the circulation pump diagram.
3) The flow rate and residual head depend on the connected heat pump and pipe dimensions ( chapter 5.2).
