Compact. Durable. Off-grid ready.
The monoBOIL is a high-quality hot water boiler developed by Tigerexped and Autoterm, designed and manufactured in Western Europe. Built specifically for mobile living, it delivers efficient hot water production in campervans, tiny homes, boats, and off-grid applications—powered directly from your 12V system.

With a stainless steel tank, monoBOIL uses a powerful electric heating cartridge made from a corrosion-resistant alloy. The heating element can be preset to switch off at your desired water temperature, up to 83°C / 181°F, providing more warm shower water than you’d expect from its compact size.

✅ Key Features

• Efficient Electric Heating
  Heats via 12V/300W onboard power or external AC (shore power/inverter).

• Premium Construction
  Made from marine-grade 316L stainless steel—saltwater-resistant, corrosion-proof, and ultra durable.

• Custom Temperature Control
  Preset the shut-off temperature using the included external TSR thermostat module.

• Rotatable & Flexible Mounting
  Install vertically, horizontally, or on a slope using the rotating stainless steel clamps.

• Safe for Winter Use
  Integrated safety valve prevents overpressure and allows for fast draining for winterizing.

• Thermal Protection Recommended
  Water can heat up to 83°C—use a thermal mixing valve or set a lower shut-off temperature to prevent scalding.

💧 Why SMALL is More Than Enough

The monoBOIL heats water far above shower temperature, allowing you to mix in cold water and extend the usable volume significantly. A 3L tank can provide much more warm water than its capacity implies.
