Duoetto water heater

Designed specifically for the caravan, marine and RV market, it runs on mains power when available and automatically switches to 12V when not.

Drawing 4.6A at 240V (1000W) and 25A at 12V (300W), the compact, 430x220x230mm Duoetto is manufactured to IPX4 for protection against ingress of water. It features a stainless steel tank and high-density insulation, an outer case with service and inspection points, over-temperature and run-dry protection, combination brass pressure relief and non-return valve, and comes with male and female DC connectors. Where mains power is available, you can select within a 30-75°C temperature range.

It sells for $380, or $395 including postage within Australia, and there's a three-year warranty on the tank and 12 months on parts.
