Waterco Electrochlor ECO Mineral Salt Chlorinator

At a Glance

The Waterco Electrochlor ECO is a salt chlorinator in 2000, 2500 and 3000 sizes for pools up to 100,000 litres in a temperate climate. It makes chlorine from pool salt or Waterco Mineral Crystals, and it also runs your variable speed pump, a second pump, a valve actuator and a light or other gear. Waterco's website calls it the Electrochlor Mineral chlorinator.

Ideal for

• Pools up to 100,000 litres wanting hands off sanitising
• Pools with a Waterco variable speed pump that should change speed on a schedule
• Pools with in floor cleaning or a water feature that needs a second pump or valve actuator
• Owners who want WiFi control (WiFi versions)

Key Specs

• Electrochlor ECO 2000: 20 g/hr chlorine, pools up to 60,000 litres in a temperate climate (48,000 litres tropical), 105 W, 5.4A DC output
• Electrochlor ECO 2500: 25 g/hr chlorine, pools up to 80,000 litres in a temperate climate (60,000 litres tropical), 115 W, 5.8A DC output
• Electrochlor ECO 3000: 30 g/hr chlorine, pools up to 100,000 litres in a temperate climate (72,000 litres tropical), 130 W, 6.0A DC output
• Power: 170 to 264V, 47 to 64 Hz input, 10A maximum total current, 8A maximum for the pump outlet, 21V cell voltage, IP23
• Salinity range: 4,000 ppm minimum, 5,500 ppm optimum, 6,000 ppm maximum
• Salt: runs on ordinary pool salt, or Waterco Mineral Crystals. Waterco's rule of thumb is about 1 kg of salt per 1,000 litres to lift the level by 1,000 ppm, so 420 kg takes a 70,000 litre pool from nothing to 6,000 ppm. Use pure pool salt with no additives
• Cell: titanium electrodes in a clear UV stabilised acrylic housing so you can see the plates. 13 plate cell on the standard versions
• Control: easy to read display with pool temperature, variable speed pump compatibility, dual pump control, valve actuator control, a second general purpose outlet for lights or other gear, low chlorine mode (10%), built in alarms and a diagnostic menu
• Flow protection: detects no flow and slows a variable speed pump to recover, then switches the pump off if flow does not come back
• Versions: standard, WiFi, premium cell, and WiFi with premium cell. Premium cell versions carry a premium salt cell. Waterco lists its premium salt cells with a 4 year warranty against 3 years for a standard 13 plate cell, and does not publish more on the difference, so ask us if you want to know whether it matters for your pool. Waterco does not publish app details for the ECO WiFi, so ask us if the app features matter to you
• Sizes 1000 and 1500: not listed here as Waterco publishes no specs for them

Why We Like It

This is the one to buy if you want the chlorinator to run the whole equipment pad, not just make chlorine. The control side is what you are paying for over a Hydrochlor or Digichlor, so if you only want chlorine and a timer, save the money. Size by pool volume with a margin: the limits above are for a temperate climate, so if you are near one, go up a size. The WiFi version is worth it only if you will actually use the app.

Installation

The cell plumbs into the pool return line and the power pack mounts on a wall near the pump, with the supplied cabling between them. Fit it yourself, or use a pool installer or plumber. The power pack needs a licensed electrician to connect to a fixed supply.

Warranty & Support

3 year warranty on the power pack and 3 years on the salt cell, conditional on the install and use following Waterco's terms. Commercial installations are covered for 1 year. Waterco lists its premium salt cells at 4 years against 3 for a standard cell. DIY installing? Warranty applies when the install follows the supplied install guide. Questions?
