Onsen - ON-7L-DP30-ACT1L- HKIT, 7L Outdoor Propane Portable Tankless Water Heater 50K BTU SKU: ON-7L-DP30-ACT1L- HKIT

Instant hot water for outdoor and off-grid use.

The Onsen 7L Portable Tankless Water Heater delivers instant hot water on demand with increased heating power and flow capacity, making it well suited for camping, hunting camps, off-grid cabins, horse trailers, pet washing stations, and other outdoor applications. Designed to heat late spring and early fall inlet water temperatures (around 45°F / 7°C and warmer), the 7L offers greater heating capacity for cooler inlet water and is well suited for temporary outdoor installations.

Fueled by propane, the Onsen 7L provides 50,000 BTU/hr of heating power, runs on a standard 20 lb BBQ propane tank, and can provide up to 10 hours of hot water runtime (usage varies by temperature settings, inlet water temperature, and flow rate).

• 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
