The Onsen 10L Portable Tankless Water Heater is Onsen's most powerful portable water heater and can turn freezing water into instant hot water so you can enjoy a hot shower on all your outdoor adventures.
Ideal for heating spring / fall water temperatures below 45°F / 7°C, the Onsen 10L turns freezing water into instant hot water on demand and features an electronic ignition (no pilot light and no wasted gas) activated by water pressure and flow.
Designed for the ultimate portability and accessibility wherever you roam, Onsen is the only portable water heater on the market featuring a dual-ignition system with two convenient options to choose from when you're venturing outdoors. Get started with two "D" cell batteries or connect to a 12 volt power source.
Featuring a premium shower head, digital screen and included 12V battery clips, the Onsen 10L runs on a standard propane tank and is perfect for hunting camps, off-grid cabins, camping, boating, pet grooming, horse trailers, stables or simply rinsing off by the pool.
