Pros and Cons

Pros:

• True instant hot water—seconds from cold to steamy.

• Energy efficient—no wasted gas heating idle tanks.

• Bright digital readout for precise temp control.

• Lightweight for easy RV/truck install or transport.

• Safety features prevent accidents reliably.

Cons:

• Needs steady water flow (min 0.5 GPM) or it shuts off.

• Propane only—not electric or natural gas.

• Initial lighting takes practice in wind.

• Louder fan/burner noise than tank models.

Detailed Review

I’ve run this heater through dozens of camping weekends, RV trips, and cabin stays, powering showers for 2-4 people daily. Hookup is straightforward: connect propane regulator to tank, water hose to inlet (garden hose thread), outlet to included showerhead or faucet. Prime with water, turn knobs, press ignite—flames whoosh, display lights up.

Heating Performance: From 50°F groundwater, it hits 110°F in 3-5 seconds at 1.8 GPM—plenty hot for showers. Digital temp holds steady (±2°F); adjust up for winter (max 122°F). Heated a 10-minute family shower no problem; flow drops gracefully if overloaded.

Portability Test: At 18 lbs, one person carries it easily. Mounted on RV exterior with brackets (not included); carry handles shine for tailgating. 20lb tank gave 50 hours over two weeks—impressive efficiency. Shower wand’s 360° swivel reaches everywhere.

Safety and Display: Overheat shut-off kicked in once (kinked hose)—smart save. Display shows “88” error for low flow, guiding fixes. Low-water cutoff prevents dry-firing. Fan cools unit post-use; stainless holds up to rain splashes.

Real-World Use: Camped in 40°F mornings—delivered toasty rinses. RV boondocking: ran off fresh tank for days. Cabin kitchen: instant hot for dishes. Noise like a loud hairdryer—fine outdoors. Winter tip: insulate inlet hose. Minor propane smell at startup (ventilate). After 100+ hours, no leaks or rust; clean burner yearly.

Pro move: Use filter on water inlet for sediment-free life.
