The Onsen 10L Portable Tankless Water Heater with 3.0 RV / Marine Diaphragm 12V Water Pump and 1.0L Accumulator Tank allows you to enjoy a hot shower outside anytime, anywhere.

Ideal for heating spring / fall water temperatures below 45°F, 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.

The 12V Water Pump supplies the necessary water pressure to your tankless water heater while the small 1.0L Accumulator Tank acts as a pressure buffer to allow for a quieter, smoother flow and give you better control of hot water temperatures.

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.

Bring the comfort of Onsen to all your outdoor adventures!

Please note that pump water hoses shown in image are not included.

works as advertised

Nice stream of hot water and amazingly quiet pump prefect for an offgrid cabin or on your camping trip. Have several fixtures attached inline and still enough psi to power the on demand shower attached in series to a rain barrel

Best water heater

This is a very good product , we used it for a 10 day hunting trip and worked 110% , shower has great pressure and easy to control the water temperature . Was easy to put together but wished I bought the brass quick connect hose connectors as I had to pick up some cheap plastic ones at hardware store and they leaked a little . Thanks again for getting mine to me before my hunt . Very good customer service.

Only tried it once so far

I ordered this system for my off grid cabin. I received it within days of my order. I set it up in my driveway to run off my garage hose so I didn't try the pump or accumulator. I turned on the water to the system and opened the shower valve. It started up and I had hot water in seconds. It was warm on full water flow but when I turned down the flow rate I could get it pretty hot with still a decent flow. I will set it up in the spring with the pump using a deep cycle battery. That will give it the real test for the full system.
