Common questions
- Is over 100 l/hr enough for my boat?
- Work from crew and habits, not boat length. Frugal cruising is 10 to 15 litres per person per day; daily showers and a washing machine push past 30. Four people at 25 litres is 100 litres a day, which a system in this band makes in 1.0 hours or so.
- Should I buy more output than I need?
- Usually yes, within reason: a higher-output system spends less time running, which means less noise and less wear per litre. The catch is that on a conventional pump, higher output normally means higher draw, so check the Wh per litre rather than assuming bigger is kinder to the bank.
