The monoBOIL is a premium electric water heater designed for mobile applications, including campers, RVs, boats, and tiny houses. Providing a reliable hot water supply, it efficiently heats water up to 83°C, ensuring comfort wherever your adventures take you.
A perfect match with solar panels!
It operates from a 12/24V onboard battery, a 230/120V shore power connection, or a properly sized inverter.
monoBOIL comes in different sizes to suit your needs. Since it heats water up to 83°C, mixing with cold water significantly increases the available warm shower water.
Built for durability, the boiler boasts a saltwater-resistant 316L stainless steel body and a shockproof, impact-resistant housing for long-lasting performance. Its corrosion-resistant electric heating coil ensures reliable operation in any environment.
monoBOIL offers flexible installation on the floor, wall, or sloped surfaces. Its cylindrical shape allows rotation within the two mounting clamps, ensuring a practical fit in any vehicle.
If the system pressure is too high, a safety valve opens and prevents damage or leaks to the boiler and water system in the vehicle.
The safety valve has a lever that is used to empty the boiler to the outside via the drain hose (not included). This means you can quickly make your system winter-proof at this point.
The monoBOIL hot water boiler is compatible with 12V or 24V DC systems and can also run on 230V or 120V via an inverter or shore power.
Closed-cell polyurethane foam insulation for minimized heat loss.
The boiler automatically turns off when the target temperature is reached.
Built-in in the 120/230V versions, as an external module (TSR, included) in the 12/24V versions.
Each model integrates seamlessly into existing setups, works independently, and provides dependable hot water solutions tailored to specific needs.
The small 3-liter boiler provides a quick and reliable hot water source for campers, vans or boats where space is at a premium.
