Hot-water values assume 60,000 L/year heated from 20°C to 45°C at 90% efficiency. The total adds the value of 3,000 L/year of distilled water, estimated using 19 L bottled-water reference prices, to that market's hot-water estimate. These are not current quotes or projected savings; check local prices and costs.
