Common questions
- How efficient are Spectra watermakers?
- Across the 4 models we table, Spectra runs from 4.5 to 4.5 watt-hours per litre. All of them use energy recovery, which is why the whole range sits in the low band.
- What does a Spectra watermaker cost in Australia?
- Indicative pricing runs from $6,000 to $14,500, excluding freight, duty and installation. Australian dealer pricing is usually all-inclusive and reads higher, so treat these as a starting point and ask a stockist for a landed AUD figure.
