ADVANCED Hybrid TRI water heater 20L Bluetooth

The Advanced Overlands Hybrid water heater offers three convenient heating options: 12V DC, 240V AC, or integration with your diesel heater—ideal for campervans or marine hot water systems year-round.

The 200W 12V element can run off your leisure battery and solar setup, making it perfect for off-grid use.

When connected to mains power, the 240V AC element delivers 1500W of heating power, making it a great option for campsites and marinas or most commonly from an inverter which are available here

The new designed internal tank now has a pass through to allow heating via 75mm ducting from your diesel heater. No extra heat exchanger or extra waterpipes/joints needed.

The Advanced Overlands hot water system heats water up to 75°C and maintains a consistent, comfortable shower temperature—perfect for multiple users in your motorhome or narrowboat.

The 20L insulated and pressurised tank connects easily to your existing water supply, featuring built-in tank connectors and requiring minimal power to maintain temperature. It’s compatible with all water pumps up to 45 PSI and includes ½” male BSP fittings, suitable for all standard plumbing connections. If you plan to use a pump with higher pressure than 45 PSI, please contact us for advice.
