Just set and go!

Two ranges, 42 models, multiple control modes and an easier life – with zero call-backs! Our new ecocirc and ecocirc+ ranges offer a smarter choice in the residential circulators market by combining high efficiency, simplicity and reliability in a single cost effective package. Compact and easy to install, all models feature a unique “one turn control knob” to set up control modes and speed settings. An interchangeable plug connection, automatic airpurge and a multicolor LED come as standard. The full ecocirc range reaches an EEI level of ≤0.18.

An even smarter choice

Our ecocirc+ version takes energy savings, simplicity and control to a whole new level. Featuring a digital display and additional operating modes, like Night Mode and eAdapt, it automatically analyzes and adapts itself to the optimal settings, reducing power consumption by up to 80%. Bluetooth wireless technology allows you to stay in control from a mobile phone, tablet or laptop.

Robust, reliant and cost-efficient

The ecocirc and ecocirc+ ranges are precision engineered by Xylem, based on more than half a century of R&D expertise and real-life testing experience.

Our ambition in the HVAC sector is, quite simply, to give you a smarter choice of circulation pumps – easier-to-install units that just keep on running, delivering high efficiency and good value for money, day in and day out.

Cutting electric bills and CO₂ emissions

Studies show that 10–15% of the electricity consumption in domestic households is due to heating circulators. The ecocirc motor and hydraulics are carefully engineered to minimize this. All ecocirc pumps feature high-efficiency ECM motors that allow energy savings of up to 80% compared to conventional circulators. The EEI level, rated at ≤0.18, ensures a fast payback on investment.

1. Always safe

The built-in dry-run protection stops the pump and prevents damage if it runs without water.

2. High visibility

A larger, easier-to-read digital display facilitates quick viewing of the pump’s operating status, warnings and alarms (ecocirc+ range).

3. Connectivity

Bluetooth wireless technology for external control and monitoring via laptop, smartphone and tablet (ecocirc+ range).

4. Always hot and protected

The insulation shell keeps the temperature of the pumped liquid and surrounding environment at just the right level and provides protection during transportation.

5. Automatic air purge

The automatic air purge mode facilitates quick and immediate air venting for safe operation.

6. Best-in-class energy efficiency

The high efficiency ECM motor and optimized hydraulics keep your operational costs to a minimum. EEI level ≤ 0.18.

7. Economical operations

Night Mode and eAdapt operational modes ensure optimal comfort at the minimum cost (ecocirc+ range).

8. Quick and easy to install

Interchangeable plug for electrical connection. The female plug is also compatible with male plugs from circulators previously installed by third parties.

Ready, set, go

Simplicity is key for the new ecocirc range. Lightweight and easy to install, these robust circulators are all equipped with a convenient, multifunctional control knob to select functional modes and speed settings. You also get just the right level of display information to monitor the circulator’s status. This is ecocirc, a smarter choice.

Lowara-Ecocirc-Front.jpg

1. Constant pressure (1-2-3)

Recommended for underfloor heating.

2. Proportional pressure (A-B-C)

Recommended for thermostatic radiator valves.

3. Fixed speed (I-II-III)

Recommended for boiler feed, single-pipe heating systems or systems with hydraulic separators.

4. eAdapt

Automatic set-up of circulator performance to ensure minimum power consumption.

5. Automatic air purge

Facilitates quick and immediate air-venting for safe operation.

6. Digital display

The 3-digit display alternates automatically to show power consumption, head and flow rate.

7. Multicolor LED

Green: Circulator is working properly
Green (blinking): Automatic air-purge is running
Yellow: Night Mode function (ecocirc+ range)
Yellow (blinking): Stand-by
Red: Pump failure or dry run

8. Connectivity LED

Green: Bluetooth wireless technology to a remote interface.

9. Night Mode and Connectivity button

Night Mode – to be activated with one of the other functional modes – ensures minimal power consumption at night time. Use the Bluetooth wireless technology to switch to a remote interface and set up the circulator.
