Affordable and Convenient Hot Water for Your Campervan
The Advanced Overlands heater provides reliable hot water using either 12V DC or 230V AC power—ideal for campervans or marine hot water systems.
The 200W 12V element runs efficiently from your leisure battery and solar setup, making it perfect for off-grid use.
The 230V AC element delivers 1500W of heating power, ideal when connected to mains electricity or used with an inverter.
The Dual Element tank supports both power sources and is easily managed with a pre-wired LCD controller.
For solar setups, the 12V DC element can also be wired through an A30 controller for use as a solar dump.
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 10L 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.
