Water Makers Australia Performance Double 140L · 12V feed
Nameplate-based estimate, not measured total draw. The total above adds the manufacturer's published high-pressure motor rating and feed-pump rating. It makes the system comparable without pretending that component nameplates are a power-meter result. It is shown so the system can be compared at all, and excluded from our best-and-worst-in-table claims until confirmed. Nameplate estimate: 1.5 kW high-pressure motor rating plus 110 W feed pump. This is not measured total running draw; the motor rating may describe shaft output rather than electrical input. How we source figures.
What you are actually buying
Drawn to this model’s own published specification: modular, 2 × SW30-2540 membranes, and a pump driven by an AC 240V motor.
What it costs to run
A four-person crew using 25 litres a head needs 100 litres a day. On this system that is:
This is an AC system, so it needs a generator, shore power or a large inverter. The Wh figure is what the generator has to cover.
Is it worth it?
At 11.5 watt-hours per litre it sits mid-table: 3.1 times the energy of the most efficient system we rank, and about 1.7 times less than the thirstiest. 1,150 Wh puts 100 litres in the tank.
Suits
- Filling tanks in a short window. At 140 nominal litres an hour, 100 litres takes 0.7 hours — the length of an engine run you were making anyway.
- Awkward spaces. The modules mount separately, so they fit around obstructions a single frame will not clear.
Look elsewhere if
- Boats without a generator or a large inverter. 1,610 W on 240 V is not something a modest inverter starts happily.
- Boats you cannot drill. This is an installed system: intake, seacock, brine discharge and a wiring run, quoted separately from the unit.
Worth pricing against it: Schenker Zen 100 makes 100 litres an hour at 4.0 Wh/L, so the same 100 litres costs 750 Wh less every day — for $1,809 more up front. See the Zen 100 →

Common questions
- How much power does the Water Makers Australia Performance Double 140L · 12V feed use?
- It draws 1,610 W and makes 140 nominal L/hr, which works out to 11.5 watt-hours per litre. Making 100 litres — four people at 25 litres a head — costs about 1,150 Wh.
- How long does the Performance Double 140L · 12V feed take to make a day's water?
- At its rated 140 nominal L/hr, 100 litres takes about 0.7 hours. Output falls in cold or silty water, so treat that as a best case rather than a promise for every anchorage.
- How much does the Water Makers Australia Performance Double 140L · 12V feed cost in Australia?
- Our indicative figure is $7,791, taken from European and US dealer listings and excluding freight, duty and installation. Australian dealer pricing is usually all-inclusive and reads higher. Ask a stockist for a landed AUD quote before you budget.
- Who sells the Water Makers Australia Performance Double 140L · 12V feed in Australia?
- 1 verified Australian business is listed as Water Makers Australia dealers or specialists, including Water Makers Australia. Each entry links to the manufacturer or company page that proves it.
- Is the Performance Double 140L · 12V feed efficient?
- It ranks 23 of 34 rated systems in our table on watt-hours per litre, where lower is better. The best in the table is 3.7 Wh/L. It uses a conventional high-pressure pump, which is the main reason it sits above the energy-recovery systems.
- Is the Water Makers Australia Performance Double 140L · 12V feed worth it?
- At 11.5 watt-hours per litre it sits mid-table: 3.1 times the energy of the most efficient system we rank, and about 1.7 times less than the thirstiest. 1,150 Wh puts 100 litres in the tank. It suits several cases: Filling tanks in a short window. At 140 nominal litres an hour, 100 litres takes 0.7 hours — the length of an engine run you were making anyway. Look elsewhere if: Boats without a generator or a large inverter. 1,610 W on 240 V is not something a modest inverter starts happily. We publish no opinion on build quality or reliability, because we have not tested it.
