Check the listing for details. Pumpengruppen Set Two Mixed Heating Circuits Electronic Regulated Mixer Circuit. Color: Black, Width: see description, Condition: New, Made in Germany. Listed at 1609.36 USD. The ECOMIX ENH001 pump group is a ready-to-install, professional pump group for heating circuits such as underfloor heating, wall heating, radiators, etc. with built-in three-way brass mixer and an ESBE ARA561 electric servomotor. A Wilo Para 25/6 high-efficiency pump is installed. Forward and reverse can easily be reversed from right to left. In the upper area of the pump group there are flat-sealing shut-off valves (1" IT) with built-in thermometers (0-160°C). The well-thought-out thermal insulation made of EPP ensures an optimal climate inside the insulation so that no heat build-up occurs. If the pump group is installed individually, a wall bracket can be screwed to the shut-off valves (not included in delivery). Maintaining or replacing the circulation pump is very easy without having to drain the system.
