My internet connection is too bad for a better response, but,....
I think the 'perfect' size watermaker for a couple cruising a 'normal' size boat is 60 to 100 liters per hour.
Theres a Sea Recovery one thats 65 liters per hour that uses 12 volts at 22 amps per hour. Its not an automatic system. (Tellie, can you confirm/clarify this please?)
2 solar panels in the 3 hours of maximum tropical sun from 11am till 2pm gives me about 13 amps each hour. So run for 3 hours I only draw, say, 10 amps = 30 amps.
Run every second day would give 150 litres (you lose a few from the 65 LPH so I am assuming 50 litres per hour effective) = 75 liters per day.
washing/cooking= 40 liters per day; looooooong showers 35 liters/2 = 17.5 litres showers each per day.
Cost of unit *Professionally* installed aprox $7,500- $10,000(????)
Heh! I don't know how "other way around" you guys or we are but I like knowing my water source. I like that it is soft. I like it.I know it is like a lot of things. All it takes is money. I choose to spend some on a watermaker. Lucky me.
I think there are a lot of gender generalizations running around the forum.
