Onsen - ON-10L-DP30-ACT1L- HKIT, 10L Outdoor Propane Portable Tankless Water Heater 75K BTU

SKU: ON-10L-DP30-ACT1L- HKIT

Instant hot water for outdoor and off-grid use.

The Onsen 10L Portable Tankless Water Heater delivers instant hot water on demand with higher heating power and flow capacity, making it well suited for off-grid cabins, hunting camps, horse stables, pet washing stations, outdoor wash-down areas, and other outdoor applications. Designed for heating spring, fall and winter inlet water temperatures (around 45°F / 7°C and colder), the 10L offers increased heating capacity for cooler inlet water and iswell suited for more demanding outdoor applications with higher hot water demand.

Fueled by propane, the Onsen 10L provides 75,000 BTU/hr of heating power, runs on a standard 20 lb BBQ propane tank, and can provide up to 6 hours of hot water runtime (usage varies by temperature settings, inlet water temperature, and flow rate).

  • Onsen 3.0 12V water pump (included): delivers 55 PSI water pressure and up to 3.0 GPM flow, with quiet operation and an automatic pressure switch that activates the pump when a tap or showerhead is opened
  • Accumulator 1.0 tank (included): smooths water pressure, reduces pump cycling, and minimizes plumbing noise
  • Water hose kit (included): three ½″ diameter hoses for connecting heater, pump, accumulator and water source

    Important notes
    • For outdoor use only. Not approved for indoor installation.
    • Water pressure: requires a pressurized water source of 10 PSI or more. A compatible pump system is required when drawing water from a lake or tank.
    • Water pump use: when using a pump, we recommend ½″ diameter hose from the water source to the pump and from the pump to the water heater. Ignition issues are often caused by incorrect hose diameter (e.g., 5/8″ or 3/4″).
